The US Department of Energy offers 3 tips for improving fuel efficiency through car maintenance.
- Keep your engine properly tuned – this can improve your gas mileage by an average of 4%, or about 13 cents per gallon.
- Keep tires properly inflated – this can improve your gas mileage by up to 3.3%, or about 10 cents per gallon.
- Use the recommended grade of motor oil – this can improve your gas mileage by 1-2%, or about 3-7 cents per gallon.
While this may not seem like a lot of money, consider this: together, these three tips can save you about 30 cents per gallon. If you drive 10,000 miles a year (the US average) and use 400 gallons of gas, this would $120 per year on gas (not to mention the hundreds you would have to spend on repairs if you break your car).
