I recently posted a thread bout my gas milege that i only get like 215-225 per tank. So I was wondering at what mileage do i have to change my fuel filter? and will that help me save some gas? what else there is that i can do to save some gas cuz this thing is killin me...i got 45k on my 95 max automatic....please HELP....

 

Here is what I did, and I am getting 320-350 mile per tank:

1. Changed the spark plugs with the factory NGK's
2. Changed the PCV valve
3. Changed the fuel filter
4. Changed the Throttle Position Sensor
5. Had the tranny flushed

All but #4 are considered to be part of the 60K mile service, but if you are having problems now, it would not hurt to do this. Make sure that you are running name brand gas as well. My TPS sensor made a real difference in the shift points, making it easier to save gas.

I have also seen a number of posts concerning the throttle body cleaning, but I do know if it is worth it for me yet.

By the way, I have 74K on an Auto 95 GXE

 

A dirty/clogged fuel filter will restrict the amount of gas the engine receives so it should not use more gas but a dirty air filter will restrict air flow which will cause your engine to use more gas than required. The above mentioned tune will help out also. If you suspect their dirty, use injector cleaner cause if their dirty they will also waste gas.

 

just a thought.
