Will changing the fuel filter in my car better my gas mileage?

Not really, unless it Actually clogged. Don%26#039;t throw parts at it. Just do regular matence on it and keep plenty of air in the tires and use the AC conservativly, Keep windows up at highway speeds, drive like a grandma. Drive so you use the brakes the least. 55mph is about the most efficient crusing speed. Thats about all you can do for gas milage.





Unless you go extreem and put smooth hubcaps, belly pans (or air dams) and wheel skirts to improve arodymanics. Also for some cars, upgrading the ignition may help, but costs a lot.|||Yes, but you need to also change the oil and the air filter. If you have a big car, you will always get bad gas milage.|||It couldn%26#039;t hurt. You should change all filters on a periodic basis to keep your car running the best it can.
