According to the United States Environmental Protection Agency guide on steps to follow to reduce pollution from vehicles and engines, getting regular tune-ups, following a strict maintenance schedule, and using recommended motor oils are just some of the practices that help with eco-friendly performance.

The following maintenance practices are also recommended for achieving these objectives:

Air Filter Replacement

The air filter is crucial in maintaining the engine's air intake system. A clean air filter ensures that the engine receives an adequate supply of clean air, which is vital for efficient combustion. It is recommended that the air filter be inspected every 12,000 to 15,000 miles and replaced if it appears dirty or clogged. 

Regular Oil Changes

Engine oil lubricates moving parts, reduces friction, and helps dissipate heat. Over time, oil degrades and becomes contaminated, leading to increased engine wear and reduced efficiency. It is advisable to follow the manufacturer's recommended oil change intervals, typically every 5,000 to 7,500 miles, depending on the type of oil used. High-quality, low-viscosity synthetic oils can enhance engine efficiency and reduce emissions.

Tire Maintenance

Proper tire maintenance is critical for minimizing rolling resistance and maximizing fuel efficiency. This includes maintaining the correct tire pressure, which should be checked monthly. Under-inflated tires can decrease fuel efficiency by up to 3.3%. Regular tire rotation and alignment also ensure even tire wear and optimal vehicle handling.

Spark Plug Inspection and Replacement

Spark plugs are integral to the ignition system, and their condition directly affects engine performance and emissions. Worn or fouled spark plugs can lead to misfires, increased fuel consumption, and higher emissions. To maintain efficient combustion, it is recommended that spark plugs be inspected from 30,000 to 100,000 miles and replaced as needed.

Fuel System Cleaning

Deposits can accumulate in the fuel system over time, affecting injector performance and fuel atomization. Periodic cleaning of the fuel injectors and using fuel additives can help maintain optimal fuel flow and combustion efficiency. This practice can lead to improved power output and reduced emissions.

Exhaust System Maintenance

The exhaust system, including the catalytic converter, plays a vital role in reducing harmful emissions.

Environmental Conditions as an Overlooked Factor in Efficiency

Eco-friendly modifications and smart driving habits play vital roles in improving fuel efficiency—but seasonal environmental conditions, particularly cold weather, can significantly undermine those efforts.

According to the U.S. Department of Energy in their guide about Fuel Economy in Cold Weather, low temperatures can significantly impact vehicle efficiency, with conventional gasoline cars experiencing a 10% to 20% fuel economy loss in city driving and up to 33% on short trips. 

Hybrid vehicles are even more affected, with fuel economy dropping between 20% and 40% in city conditions and as much as 45% on short drives. Electric vehicles (EVs) see the most severe declines, with overall fuel economy falling by 39% in mixed city and highway driving, primarily due to the increased energy demand for cabin heating.

On the other hand, hot weather presents a more complex picture. While summer conditions can actually improve fuel economy in some ways—engines reach optimum operating temperature faster, warm air reduces aerodynamic drag, and summer gasoline blends contain slightly more energy—these benefits can be quickly offset by heavy use of air conditioning (A/C).

Another guide by the U.S. Department of Energy about Fuel Economy in Hot Weather, running the A/C in very hot conditions can reduce fuel economy by more than 25%, especially on short trips. For hybrids and EVs, the percentage reduction in efficiency can be even higher, as climate control systems drain more energy relative to total power demand.

Rolling down windows as an alternative to using A/C can help at lower speeds, but at highway speeds, it increases aerodynamic drag and reduces fuel efficiency. A practical workaround is to vent the sunroof or open windows briefly at the start of a trip to let hot air escape—lessening the load on the A/C without significantly impacting aerodynamics.

In both hot and cold conditions, strategic preconditioning of the cabin climate—such as pre-cooling an EV while it’s still plugged in or avoiding A/C use while idling—can help preserve fuel or battery efficiency. Parking in shaded areas, using a sunshade, and managing climate control settings wisely are small, actionable steps that can yield measurable efficiency gains across all vehicle types.
