What maintenance can improve gas mileage?

Answer 1

Rotate your tires every 3,000 miles. Change the oil at that time as well. Another area to look at for improvements on gas mileage is also your air intake sensor and air filter. If your air intake sensor is dirty, it will cause your engine to change the ratio of your air to fuel mixture. I've wiped my sensor off with just a q-tip and removed what seemed to look like soot from it. It helps. Change the airfilter when you notice the sensor getting dirty. If the sensor looks real dirty, you might need to replace it. On older vehicles, I've used the sea foam product in a full tank of gas. It blows the carbs out of the engine, which makes it run more efficiently and adds life to your engine. Other things you can look at just to improve overall gas mileage: make sure you're not carrying around that extra bag of dog food you didn't haul in the night before; run your AC in moderation (put it on the mid setting instead of running it on high, then turning completely off once you're comfortable); don't drive with all the windows down to compensate for not using the AC (this causes quite an air drag on your car and you'll use more fuel to just go forward!) . Driving anything over 65 mph burns more gas (so they say), but good luck staying at that speed on the interstates where 75 mph is the speed limit and those around you are doing 90!
