Simple Ways to Improve Your Car’s Fuel Economy: Essential Tips to Boost MPG and Save Fuel

Fuel economy — often expressed as miles per gallon (MPG) — measures how far a vehicle travels on a given amount of fuel and directly affects operating costs and environmental impact. This article explains practical, evidence-based ways to improve your car’s fuel economy through driving habits, routine maintenance, diagnostics, tire care and simple lifestyle changes so you can reduce fuel consumption and increase MPG. Poor fuel economy usually stems from avoidable causes such as aggressive driving, mechanical inefficiencies, underinflated tires or clogged fuel system components; correcting these offers measurable savings and improved engine efficiency. Below you will find focused guidance on the most effective driving habits to save fuel, the maintenance tasks that typically yield the biggest MPG gains, how to diagnose and fix persistent fuel-consumption problems, tire-related steps that have direct numeric impacts, and a concise top-10 checklist for immediate action. Throughout the guide we reference relevant services such as Air Filter Replacement, Oil Change, Tune-Ups, Fuel Injection Cleaning, Wheel Alignment and Diagnostics to help you decide when to DIY and when to seek professional help.

What Are the Most Effective Driving Habits to Improve Fuel Economy?

Driving habits are behavioral choices that directly influence instantaneous fuel consumption and long-term MPG. Smooth acceleration, consistent speed, reduced idling and minimizing unnecessary weight reduce fuel demands by lowering peak fuel flow, cutting rolling resistance and limiting aerodynamic drag, which together improve engine efficiency and overall fuel economy. Adopting modest speed limits on highways and anticipating traffic reduces fuel bursts during acceleration and prevents inefficient braking cycles, delivering steady MPG improvements. The following practical habits are simple to adopt and can generate quantifiable savings when applied consistently.

Smooth, anticipatory driving saves fuel in everyday conditions:

• Drive with gradual acceleration and gentle braking to reduce fuel spikes and maintain momentum.
• Use cruise control on steady highway stretches to hold an efficient speed and avoid speed oscillation.
• Anticipate traffic by scanning ahead and easing off the throttle to limit stop-start cycles.

These habits reduce instantaneous engine load and create conditions where maintenance and tire care improvements compound to a higher overall MPG.

How Does Smooth Acceleration and Gentle Braking Save Fuel?

Smooth acceleration and gentle braking save fuel by reducing sudden demands on the engine and minimizing energy lost as heat during braking. When you accelerate gradually you avoid high fuel injection rates and large throttle openings, which lowers the rate of fuel consumption per mile; similarly, smooth braking preserves kinetic energy that would otherwise be wasted and require re-acceleration. In city driving the difference between aggressive and smooth driving can be several percent of fuel use per trip, and over time those small percentages compound into meaningful savings. Practically, maintain steady throttle input, anticipate signals and slowdowns, and allow following distances that prevent frequent braking.

These techniques naturally lead to reduced wear on drivetrain components and better tire life, which ties directly into maintenance routines covered below.

Why Should You Minimize Engine Idling for Better MPG?

Engine idling consumes fuel without producing distance, so minimizing idle time directly reduces fuel consumption and improves average MPG. Modern engines require minimal warm-up time and restarting the engine for short waits typically uses less fuel than prolonged idling; exceptions include safety or extreme-weather scenarios where cabin conditions are critical. For common situations like pickups, drive-throughs or waiting in a stationary vehicle, turning the engine off when safe and legal saves fuel immediately and reduces unnecessary emissions. Tracking and reducing idle minutes per week yields cumulative fuel savings and supports cleaner engine operation.

Reducing idling also shortens intervals between routine maintenance events because lower cumulative engine-on hours reduce component wear and thermal stress, connecting behavior to service outcomes discussed later.

How Can Optimal Gear Usage Enhance Your Car’s Fuel Efficiency?

Using the correct gear and keeping engine RPM in an efficient range lowers fuel consumption by reducing internal friction and pumping losses. For manual transmissions, shift up earlier to keep RPMs moderate during steady cruising and avoid lugging the engine at excessively low revs; for automatics, gentle throttle inputs and using overdrive gears where safe helps the transmission select lower engine speeds. Cruise control is useful on steady, flat roads to maintain efficient speeds. Overall, staying within the manufacturer-recommended RPM band for your engine reduces fuel flow per mile and improves long-term MPG.

Efficient gear usage complements maintenance such as timely oil changes and tune-ups, because a well-serviced engine meets its efficiency potential more readily when operated in the right RPM window.

What Role Does Reducing Vehicle Weight and Drag Play in Fuel Economy?

Reducing vehicle weight and aerodynamic drag cuts the energy the engine must supply to move the car, leading to measurable MPG gains. Extra cargo, roof racks and unnecessary equipment increase rolling resistance and frontal area; as a broad rule of thumb, removing about 100 lbs (about 45 kg) of excess weight can improve fuel economy by about 1–2% depending on vehicle and driving conditions. Likewise, roof racks and external carriers increase drag at higher speeds and can reduce highway MPG notably. Regular decluttering, removing permanent roof attachments when unused and storing heavy items only when needed are simple, effective steps to preserve fuel economy.

Combined with steady driving habits, lower weight and reduced drag create compounding fuel savings that show up on both short and long trips.

Which Car Maintenance Tasks Most Improve Fuel Economy?

Maintenance tasks are mechanical interventions that restore or preserve engine and drivetrain efficiency; targeted services can produce measurable MPG improvements by addressing friction, air/fuel mixture, ignition timing and rolling resistance. Regular oil changes reduce internal friction, clean air filters restore optimal airflow to the combustion chamber, spark plug replacement improves ignition efficiency, fuel injection cleaning restores correct spray patterns, and wheel alignment reduces rolling resistance caused by uneven tire wear. Below is a comparison that summarizes these maintenance tasks, their typical MPG impact and recommended service frequency to guide prioritization.

The table below compares common maintenance tasks and their expected contributions to fuel economy.

How Does Regular Oil Change Boost Your Car’s MPG?

Regular oil changes reduce engine friction, keep moving parts lubricated and help maintain optimal engine temperature, all of which support efficient combustion and reduce fuel consumption. Using the manufacturer-recommended oil grade also matters because lower-viscosity, approved oils reduce parasitic losses while preserving protection; choosing the correct oil can yield small but consistent MPG improvements, often estimated around 1–2% versus degraded or incorrect oil types. Monitoring oil condition and adhering to scheduled changes prevents increased friction that raises fuel consumption and accelerates component wear.

Keeping oil fresh also supports sensor longevity and reduces the chance of secondary faults that can negatively affect fuel trims and emissions, linking routine maintenance to diagnostic outcomes covered next.

Why Is Air Filter Replacement Crucial for Fuel Efficiency?

A clean air filter enables correct air-fuel mixture and efficient combustion; a clogged or dirty air filter restricts airflow, can cause rich running conditions and reduce MPG while hampering acceleration. Symptoms of a restrictive air filter include reduced throttle response and slightly higher fuel use, and replacing a badly clogged filter can restore a percent or more in MPG depending on condition. Regular inspection and timely Air Filter Replacement ensure the engine breathes cleanly and efficiently, directly impacting fuel consumption.

Air filter checks are simple DIY steps for many drivers, and scheduling replacements during service visits prevents prolonged periods of inefficient combustion and higher fuel consumption.

How Do Spark Plugs and Fuel Injection Cleaning Affect Fuel Consumption?

Spark plugs and fuel injectors are critical meronyms of the combustion system: spark plugs provide reliable ignition and injectors meter fuel precisely; wear or deposits hinder both functions and lead to incomplete combustion or wasted fuel. Worn plugs can cause misfires and poor combustion efficiency, while gummed injectors produce uneven spray patterns that change mixture and burn less cleanly, both increasing fuel consumption. Services such as Tune-Ups and Fuel Injection Cleaning restore ignition timing and spray quality, improving MPG and drivability.Recognizing symptoms such as rough idle, reduced acceleration and a drop in fuel economy helps prioritize Tune-Ups or injector cleaning before inefficiencies compound.

What Benefits Does Wheel Alignment Provide for Fuel Economy?

Wheel alignment corrects camber, toe and caster angles so tires make even contact with the road, reducing rolling resistance and preventing uneven tire wear that forces the engine to work harder. Misalignment often presents as pulling to one side or irregular tire wear patterns, and correcting alignment restores optimal tire contact and can recover a small but measurable MPG improvement. Scheduling Wheel Alignment when tires are replaced, or if you notice pulling or vibration, preserves tire life and contributes to better fuel economy over the tire’s lifetime.Alignment works together with correct tire pressure and rotation to ensure the lowest feasible rolling resistance, which is discussed further in the tire care section.

How Can You Diagnose and Fix Causes of Poor Fuel Consumption?

Diagnosing poor fuel consumption means identifying whether the cause is behavioral, mechanical or electronic and applying targeted corrective actions; effective diagnostics combine symptom mapping, onboard scanner data and component testing to pinpoint root causes. Common causes include faulty oxygen sensors or mass air flow sensors that skew fuel trims, clogged injectors, worn spark plugs, a dirty air filter, or transmission problems that keep the engine in inefficient gears. A structured diagnostic approach prevents unnecessary parts replacement and leads to the best MPG recovery for cost spent.

If simple checks do not resolve the issue, professional Diagnostics service is the recommended next step to identify hidden electronic or mechanical faults affecting MPG.

Below is a diagnostic findings table that maps common issues to symptoms and likely fuel impact or corrective action.

What Are Common Mechanical Issues That Reduce Fuel Economy?

Common mechanical issues that reduce fuel economy include worn spark plugs, clogged fuel filters, restricted air flow, faulty oxygen sensors and transmission inefficiencies; each produces characteristic symptoms such as misfires, loss of power, rough idle or error lights. These faults affect either the air-fuel ratio, combustion completeness or driveline efficiency, which directly increases fuel consumption. Quick DIY checks include inspecting air filters, verifying tire pressure and looking for visible fluid leaks; however, many sensor faults need an OBD-II scan to identify stored codes and live-data anomalies.

When symptoms point to mechanical or sensor faults, addressing the root cause through targeted maintenance or professional service typically restores MPG to near-original levels.

How Can Engine Diagnostics Identify Fuel Efficiency Problems?

Engine diagnostics use tools like OBD-II scanners to read fault codes, monitor live sensor data such as fuel trims, oxygen sensor voltages and mass air flow readings, and perform system checks to identify anomalies that affect MPG. By comparing live parameters against expected values, a technician can locate a lean or rich condition, detect misfires, or find a sensor that reports out-of-range values; diagnostics also reveal drivability issues such as transmission slip or EGR faults that increase consumption. Professional Diagnostics services provide a structured workflow—scan, test, confirm and repair—that leads to targeted repairs rather than guesswork.

A proper diagnostic session reduces unnecessary parts replacement, identifies the quickest path to MPG recovery and supplies data to verify post-repair improvements.

When Should You Seek Professional Help for Fuel Economy Issues?

Seek professional help when the check engine light is illuminated, MPG drops significantly without behavioral change, or when DIY checks (tire pressure, oil level, air filter) do not restore expected economy; these are red flags that sensors or driveline components may be failing. Professional Diagnostics service can interpret error codes, run live-data tests and recommend corrective actions such as Fuel Injection Cleaning, Tune-Ups or more involved repairs. The cost-benefit rationale is clear: targeted diagnostics avoid replacing non-faulty parts and deliver verifiable MPG gains that often offset the service cost.

Complete Diagnostics allow you to quantify improvements after repairs, making it easier to prioritize interventions that deliver the best return on fuel-cost savings.

How Does Tire Care Impact Your Car’s Fuel Efficiency?

Tire care — covering correct tire pressure, rotation and alignment — directly affects rolling resistance and therefore MPG. Proper inflation reduces the contact patch rolling resistance while rotation and alignment ensure even wear and preserve tire performance; these actions together maintain the lowest effective energy loss per mile. Small PSI changes have measurable effects on fuel consumption, and regular checks avoid gradual pressures losses that quietly erode MPG. Below is a focused table to clarify tire-related attributes and their effect on fuel economy.

Tire care attributes and their expected impacts:

How Often Should You Check Tire Pressure for Optimal MPG?

Check tire pressure at least once a month and before any long journey to maintain optimal MPG, since temperature changes and slow leaks reduce PSI over time and alter rolling resistance. Cold weather reduces tire pressure and can noticeably cut MPG if not corrected; conversely, overinflation harms grip and increases uneven wear, so follow manufacturer-recommended PSI on the vehicle placard. Use a reliable gauge and check pressures when tires are cold for accurate readings; topping up lost PSI is a simple action that produces an immediate improvement in rolling resistance and economy.

Regular monthly checks complement scheduled tire rotations and wheel alignment to sustain consistent, fuel-efficient tire performance.

What Is the Effect of Underinflated Tires on Fuel Consumption?

Underinflated tires increase rolling resistance because more tire surface deforms and rubs against the road, causing the engine to work harder and consume more fuel. As a rough guide, losing 1 PSI can reduce fuel efficiency by around 0.2% depending on vehicle and tire; larger underinflation across tires can add up to a few percent loss in MPG, which is meaningful over months of driving. Underinflation also speeds tire wear and can compromise safety, so correcting pressure is both economical and prudent.

Keeping tires at correct PSI is a low-cost preventive measure that preserves fuel economy and prolongs tire life.

How Does Wheel Alignment and Tire Rotation Improve Fuel Economy?

Wheel alignment and tire rotation maintain even tread wear and optimum tire-road contact, which reduces irregular rolling resistance and prevents the engine from compensating for drag caused by misalignment. Typical rotation intervals (as recommended by manufacturers) redistribute wear and extend tire life, while alignment corrects steering pull and vibration that otherwise increases fuel consumption. When alignment issues are corrected, drivers often notice better steering and incremental MPG improvements that accumulate over the tire lifespan.

Pairing regular rotation with alignment checks when you notice symptoms (pulling or uneven wear) ensures tires contribute positively to overall vehicle efficiency.

What Simple Lifestyle Changes Can Help You Save Fuel Daily?

Small lifestyle adjustments reduce unnecessary driving and fuel use without mechanical changes; consolidating errands, choosing efficient routes, moderating speeds and limiting heavy accessory use all contribute to lower fuel consumption. Planning trips so multiple tasks are completed in a single outing reduces cold starts and short-trip inefficiencies, while using navigation apps to avoid peak congestion reduces stop-start fuel waste. These changes are behaviorally straightforward and can produce immediate reductions in weekly fuel consumption.

The following three changes are easy to adopt and yield frequent savings:

• Consolidate errands into one trip to reduce cold starts and multiple short journeys.
• Drive at moderate speeds and avoid frequent rapid acceleration to lower fuel demand.
• Limit use of heavy accessories and avoid roof racks when not needed to reduce drag and weight.

Adopting these habits makes mechanical investments such as Tune-Ups and wheel alignment more effective because the vehicle is being used in an efficient manner that allows those improvements to show up as real MPG gains.

How Does Driving at Moderate Speeds Improve Fuel Economy?

Driving at moderate speeds keeps the engine in a more efficient section of its fuel curve because aerodynamic drag rises exponentially with speed; generally, most cars achieve optimal highway MPG in a band slightly below legal highway maxima where the engine does not fight excessive air resistance. High-speed driving increases fuel flow notably, so maintaining moderate speeds and smoothing acceleration reduces fuel use per mile. Where safe, using cruise control on steady stretches can stabilize speed and avoid inefficient speed variations.

Stable, moderate-speed driving also reduces wear and heat stress on the engine, which supports longer-term efficiency and fewer maintenance-related MPG drops.

Why Should You Avoid Excessive Use of Air Conditioning?

Air conditioning increases engine load and therefore fuel consumption, particularly in city driving or stop-start traffic; at lower speeds, opening windows may be more efficient, while at higher highway speeds the aerodynamic penalty of open windows can outweigh AC use. Use AC sparingly and consider recirculation modes to cool faster; pre-cooling the cabin while plugged into a charger for EVs or before departure in hybrid contexts also reduces on-road AC demand where applicable. Balancing AC and window use based on speed and comfort needs optimizes fuel use without sacrificing passenger comfort.

Thoughtful AC use benefits fuel economy modestly but consistently, especially when paired with other measures such as reduced weight and smooth driving.

How Can Planning Trips and Reducing Engine Warm-Up Time Save Fuel?

Planning trips to combine errands and avoid multiple short cold starts cuts fuel waste because short, cold trips consume disproportionately more fuel before the engine and catalytic systems reach optimal temperature. Modern engines require very little idle warm-up; rather, driving gently for the first few minutes warms the engine efficiently while minimizing idling. Using apps for route planning and traffic avoidance reduces time spent in congested, low-efficiency driving conditions and lowers total fuel consumed for routine tasks.

These planning habits reduce both immediate fuel use and cumulative maintenance demands linked to frequent cold starts.

What Local Factors Affect Fuel Economy for Ann Arbor Drivers?

Local driving patterns, climate and road types in Ann Arbor influence fuel economy in predictable ways and localized interventions can help mitigate their effects. Stop-and-go commuter traffic during peak hours, cold winters that lower tire pressure and city driving with many short trips all reduce MPG compared with steady highway travel. Seasonal checks — especially tire pressure adjustments in colder months — and route planning that avoids rush-hour corridors help Ann Arbor drivers protect fuel economy. For persistent or complex issues, local professional services can provide convenient options to restore and verify MPG improvements.

How Do Ann Arbor’s Driving Conditions Influence Fuel Efficiency?

Ann Arbor’s mix of urban commuting, campus-area congestion and occasional congested arterials increases stop-start driving that raises fuel consumption relative to steady cruising. Seasonal temperature swings reduce tire pressures in cold months and slightly increase fuel use until corrected; winter driving may also increase idling times for defrosting and cabin heating, further affecting MPG. Planning driving times to avoid peak congestion and paying attention to tire PSI during seasonal shifts are practical local steps to limit these impacts.

Local drivers who combine behavior changes with routine maintenance protect their MPG against these predictable local influences.

What Common Vehicle Issues in Ann Arbor Impact Fuel Economy?

Local vehicle issues often mirror general patterns—dirty air filters from dusty conditions, clogged injectors from frequent short trips, worn spark plugs and occasional sensor faults contribute to higher fuel consumption. Drivers may notice rough idles, reduced acceleration, or a drop in MPG after seasonal transitions; these symptoms usually map to services such as Air Filter Replacement, Fuel Injection Cleaning or Tune-Ups. Proactive checks and early servicing reduce the likelihood of prolonged inefficiency.

When these symptoms appear, timely servicing by a local shop avoids the compounding fuel costs that follow deferred maintenance.

These tips work best when combined: behavior changes amplify the effect of mechanical services, and professional Diagnostics can identify which interventions will yield the greatest MPG returns for your vehicle.

Tip 1: Maintain Correct Tire Pressure Regularly

Maintaining tire pressure is a straightforward habit with immediate effect: check tires at least monthly and fill to the vehicle manufacturer’s recommended PSI. Correct pressure reduces rolling resistance and uneven wear, improving fuel economy and safety simultaneously. Use a reliable gauge and keep a small compressor or visit a gas station as needed to maintain pressures. Monthly checks pair well with scheduled tire rotations to extend tire life and sustain MPG gains.

Regular tire care is low-cost and high-impact, making it a first-line action for any driver seeking improved fuel economy.

The Impact of Tire Pressure on Rolling Resistance and Fuel Consumption

Tire pressure influences several key vehicle characteristics. This article focuses on assessing the effect of varying tire pressure on both rolling resistance and fuel consumption. Measurements were conducted using four distinct tire pressure settings. The impact of changes in tire pressure on rolling resistance was evaluated during driving tests. To measure rolling resistance during these tests, a specific measurement methodology was developed, and a device for measuring rolling resistance was constructed. The measurement of the effect of tire pressure changes on fuel consumption was carried out using a vehicle dynamometer. The results indicated a linear relationship between tire pressure and rolling resistance. These findings highlight the significance of maintaining the correct tire pressure with respect to fuel consumption.

Assessing the Impact of the change in the tire pressure on the rolling resistance and fuel consumption, F Synák, 2020

Tip 2: Schedule Regular Oil Changes and Filter Replacements

Regular Oil Change and filter replacements keep engine internals lubricated and clean, lowering friction and helping combustion systems perform efficiently; following the owner’s maintenance schedule is the best practice. Using the correct grade of oil reduces parasitic losses and supports optimal fuel use, while replacing filters prevents restrictive flow conditions. Routine servicing prevents cascading faults that might otherwise reduce MPG and increase repair costs.

Combining scheduled oil and filter care with periodic tune-ups preserves engine efficiency and supports long-term fuel savings.

Tip 3: Drive Smoothly with Controlled Acceleration and Braking

Practicing smooth acceleration and gentle braking maintains vehicle momentum and limits high fuel-flow events that occur with aggressive driving. Techniques include anticipating stops, maintaining safe following distances, and easing onto the throttle after intersections. These methods reduce the frequency and severity of fuel-intensive accelerations, improving average trip MPG. Over time, smooth driving also reduces wear on brakes, tires and drivetrain components.

Smooth driving habits magnify the benefits of mechanical maintenance and tire care by creating conditions where the vehicle operates in its most efficient state.

The Impact of Driving Behavior on Fuel Economy (Miles Per Gallon)

The results indicate that utilizing log(gas mpg + 1) as the response variable, rather than gas mpg directly, enhances model performance. This suggests that the distribution of gas mpg is skewed, necessitating a transformation for a better data fit. The study further revealed that driving behavior exerts a significant influence on fuel economy, with aggressive driving patterns correlating with reduced MPG.

Driving Behavior Improvement and Driver Recognition Based on Real-Time Driving Information, K Nie, 2013

Tip 4: Replace Worn Spark Plugs and Clean Fuel Injectors

Worn spark plugs and clogged injectors degrade combustion efficiency and increase fuel consumption; regular Tune-Ups and Fuel Injection Cleaning restore ignition and spray quality. Signs to watch for include rough idling, poor acceleration and increased fuel use; addressing these issues typically returns several percent of lost MPG. Professional Tune-Ups are an efficient way to replace key meronyms like spark plugs and filters and ensure the fuel system operates optimally.

Timely replacement and cleaning prevent inefficient combustion and preserve long-term engine performance.

Tip 5: Keep Your Car Light and Remove Excess Weight

Removing unnecessary weight and external load reduces the power required to accelerate and maintain speed, translating directly into better MPG. Declutter the trunk, remove heavy seasonal items and uninstall roof racks when not in use to reduce drag and weight penalties. Small, consistent changes to vehicle load can add up across months of driving. The practice both lowers fuel consumption and simplifies vehicle handling.

Weight reduction is an immediate, cost-free step any driver can take before or in parallel with servicing.

Tip 6: Use Recommended Engine Oil Grades for Efficiency

Using manufacturer-recommended oil grades ensures the engine runs with minimal friction and proper protection; selecting approved low-viscosity oils where specified can modestly improve MPG. Check the owner manual for correct grades and consider oil changes at qualified service intervals to maintain optimal viscosity and cleanliness. Proper oil reduces wear and engine drag while preserving fuel economy over time.

The right oil supports all other efficiency measures by keeping the engine componentry operating smoothly.

Tip 7: Avoid Excessive Idling and Plan Efficient Routes

Minimize idle time and plan trips to avoid multiple short cold starts; combine errands and use route planning to cut unnecessary miles. Modern engines warm faster while being driven gently, so idle warm-ups are seldom necessary beyond immediate safety needs. Efficient routing reduces time in congested, low-efficiency driving and lowers cumulative fuel consumption.

Planning combined with driving technique reduces both fuel use and maintenance stress on the vehicle.

Tip 8: Ensure Proper Wheel Alignment and Tire Rotation

Regular Wheel Alignment and tire rotation prevent uneven wear and maintain a consistent rolling resistance, safeguarding fuel economy and tire lifespan. Rotate tires per manufacturer guidance and check alignment if you notice pulling, vibration or uneven tread patterns. Properly maintained tires help the engine operate under lower load conditions and preserve MPG.

Pairing alignment services with tire pressure checks provides a durable base for efficient driving.

Tip 9: Limit Use of Air Conditioning and Roof Racks

Manage AC use sensibly and remove roof racks when not needed to reduce the two main sources of accessory-related fuel drag: mechanical load and aerodynamic resistance. At low speeds, opening windows may be more efficient, while at high speeds AC may be preferable; remove roof-mounted carriers when idle to avoid constant drag. These small changes reduce unnecessary fuel draw.

Balancing comfort and efficiency leads to steady, small savings that add up over many trips.

Tip 10: Get Professional Diagnostics for Fuel Economy Issues

When simple measures fail to restore MPG, book professional Diagnostics to identify sensor faults, fuel delivery issues or transmission problems that cannot be seen by eye. Diagnostics reveal precise fault codes and live-data anomalies and point to targeted services like Fuel Injection Cleaning, Tune-Ups or Oil Change that will restore efficiency. Complete Auto Service of Ann Arbor highlights Diagnostics as a practical next step and pairs it with convenience features such as same-day service, loaner cars, online scheduling, financing options (SNAP) and a 2-year/24,000-mile guarantee to support lasting repairs.

A focused diagnostic session ensures you invest only in the services that will deliver verified MPG improvements.

Tire Pressure Management for Fuel Consumption Reduction

The potential impact of active tire pressure management on fuel consumption reduction in passenger vehicles has been investigated. The analysis was performed using a model that relates rolling resistance to tire pressure. Rolling resistance was therefore used to recalculate the coast-down coefficients as functions of tire pressure. This allowed fuel consumption simulations to be performed.

Potential impact of active tire pressure management on fuel consumption reduction in passenger vehicles, S d’Ambrosio, 2019
