How to Improve Gas Mileage
You can improve your car's gas mileage through a mix of maintenance and smart driving habits. The biggest gains come from how you drive, but regular upkeep also plays a key role.
Maintenance Tips That Work
Keep your tires inflated to the right pressure. Under-inflated tires create extra drag and force your engine to work harder. Proper inflation can improve gas mileage by up to 3.3%. You can check tire pressure at most gas stations for free.
Use the correct motor oil grade. Switching to the manufacturer's recommended oil can improve efficiency by 1-2%. Look for oil labeled "Energy Conserving" on the bottle for extra friction-reducing benefits.
Replace clogged air filters. A dirty air filter forces your engine to work harder and use more fuel. This is one of the easiest checks you can do yourself: just pop your hood and look at the filter. If it looks gray or caked with dirt, replace it.
Replace worn spark plugs. Old, fouled spark plugs cause your engine to run less efficiently. Regular replacement keeps your engine firing properly.
Driving Habits Make the Biggest Difference
Drive smoothly and steadily. Aggressive driving cuts gas mileage by 33% at highway speeds and 5% in town. Avoid rapid acceleration and hard braking. Instead, anticipate traffic and maintain steady speeds.
Use cruise control on highways. Holding a constant speed saves fuel compared to speeding up and slowing down repeatedly.
Turn off your engine when idling. Letting your car run while waiting wastes gas for zero benefit. If you're stopped for more than a few seconds, shut the engine off.
Reduce weight and drag. Remove roof racks and cargo carriers when not needed. A loaded roof rack can cut fuel economy by around 5%.
