Making sure your car is tuned up properly and the oxygen sensor is functioning can greatly increase your miles per gallon. The tune up is about a 4% increase in mpg, while the oxygen sensor can increase your mpg 40%! The sensor is usually a pain, but worth it in the long run. Besides, if you have smog requirements in your state, you will have to replace the sensor anyways to pass.
Properly inflating tires saves gas and tire wear and tear. These are shoes for your vehicle and you should treat them as well as you would your own feet. There are some who say this can't make a huge difference, but you try driving with flattened tires and see how well it works.
Following the speed limit will keep you from getting a ticket and running out of gas as much. Decreasing your speed to 55 on freeways can save gas and keep you out of trouble too!
Here are some other tips that will save gas as well:
- Don't accelerate hard
- Remove excess stuff from car
- Run more than one errand at a time
- Avoid idling for long periods of time
- Change your air filter
- Carpool
