1. Use cruise control
Cruise control can save you as much as 4 MPGs by preventing constant acceleration and breaking that waste gas. Use it on a highway whenever possible to stay at a constant speed.
2. Turn off your A/C
If you don’t absolutely have to use it, then don’t. You will see better gas mileage with no A/C and windows up (use a fan) or windows down (if you car is aerodynamic). If you have a larger car like an SUV, using A/C at highways speeds may yield better gas savings.
3. Don’t idle
There is no need to warm up your car by idling, even in cold weather. The engine will warm up as you drive off slowly and accelerate smoothly—avoid rough acceleration to save even more MPGs.
4. Travel at the speed limit
Your car will go through more gas at speeds above 60 mph.
5. Clean out your trunk
Small weight adjustment won’t matter much, but if you can remove 100 pounds or more from your car, you will save at least 1 MPG.
6. Keep it tuned-up
Don’t skip oil changes and regular car checkups. Some parts fail slowly over time, causing inefficient gas consumption. Catching them early means long-term savings.
7. Change the air filter
Check with your owner’s manual for recommended intervals and be sure to replace your engine air filter frequently enough to prevent clogs.
8. Check the tire pressure
Tire pressure may rise or drop depending on the outside temperature. Check it frequently and make sure your tires always have the right amount of air for optimal performance.
9. Buy the right gas
The most expensive fuel is not always the best for your car. Get the fuel recommended for your make and model to maximize its efficiency.
10. Don’t overfill your tank
Put in only as much gas as your tank is designed for—don’t try to squeeze in a few extra drops after the nozzle stops pumping. And don’t forget to twist that gas cap tightly, so that gas doesn’t evaporate.
