I've had it with this horrible Gas Mileage! Idea's?

[climbcovey]

Im averaging 14.5mpg, partially attributed to my driving style. One improvement I made was putting a k&n air filter on. milage went up to about 16-17 mpg.

Yea I have that K&N filter.

My girlfreidn took the VX to Tahoe today and said she got 210 miles to the tank.

Funny thing she said is she stopped at almost 1/8 tank to fill up, and the tank only took 11 gallons! Arent our tanks 22 Gallons? this could be the sign of something.

How about the fuel filter? I know a friend with a civic who had never changed the fuel filter and suddenly got 2-3 mpg more when he changed it. If you've never had it changed, then I'd say it is overdue.

that would be 19 mpg. how do you figure your gas mileage? shawn

[Numba1goalie]

Yea it would be 19 MPG if I had a 11 Gallon tank. But we have what i now know to be a 22.5 gallon fuel capacity.

275 miles to the tank last week. 22.5 fuel capacity.

275/22.5=12.22

here is a list of thing I am going to fix or replace.

*Fuel Filter
*o2 Sensor
*infalte tires to 39 PSI
*Clean EGR Valve and Tube
*Replace Intake Gasket
*Check Brake Calipers for possible drag

I know we have a 22.5 gallon tank. But if you does not take 22.5 gallons at the time you fill it then you do not use the 22.5. If you drove 200 miles and it took 10 gallons to fill it up, you would divide 200 by 10 and get 20 mpg. The only time the 22.5 comes into play is if it takes 22.5 gallons when you fill it up. You are figuring your fuel mileage wrong. You need to go buy the amount of fuel you put in, not the capacity of the tank. And it sounds like your fuel gauge is wrong. shawn

I am not figuring my milage from what my girlfreind says. Shes a woman after all. They are not to be trusted right.

I am going off my experiment from last week, the week before, and since June when I bought it.

I have somewhat of an update however. Since i put my K&N filter is I had been having a problem at startup with the engine reving up and down real bad. I would imagine that somehow, the engine might of been asking for more gas too along the highway if it was reading stuff right from the MAF sensor guessing thats what was wrong.

Well i unplugged the battery for a good 15 minutes or so to reset the computer and walla, no more angry reving, and from the looks of it, I may pull of 300 miles to the tank this time around? I will let you all know when I get to the bottom of my tank.
