Ive changed every regular maintenance thing. Oil/Oil filter, Pcv valve, air filter...and im still getting bad gas mileage.
Im getting anywhere from 240-300 miles on 17 gallons, depending on when, and where i drive.
Do you all think maybe O2 sensors could be bad?
Any other thing that could be stunting my mpgs?

 

You did'nt mention spark plugs or wires there either. How's you rtire pressure?

I just found out about this site:http://www.trackyourgasmileage.com/

Looks promising!

i thought the ranger tanks were 15 gallons?

 

16.5 on reg cabs
19.5 on ext cabs.

 

I really depends on if you drive the crap out of it or not. If you spend more time in the high RPM's naturally you use a bit more gas. Weather also has a bit to do with it because a cold engine dumps more fuel

 

winter gas blend...everyones gas mileage falls...wait til summer then watch it get to about 20-24

 

I've put over 20 gallons of gas into my 95 Ranger Extra Cab before. More than once! Now..........don't know if the pump was accurate or not, but I did it at different stations too.

well first off, you cant go by total number of miles to a tank for MPG calculations, it is completely inacurate. You need to know the number of miles driven over the number of gallons of gas used, so fill the tank, reset the trip meter, drive, when you fill the tank again divide the number of miles you went by how many gallons you had to put in. Do this for a few tanks and when you have an idea of what you are actually getting for MPG then you can wonder if it is bad or good.

 

thats not good. I can get 400-450 miles out of a full tank (or at least when the Check Gage light come one.) and I havent replaced a thing yet. only mechanical change is a K&N Filter with the airbox mod.
