Default RE: Still gettin ****ty mpg, next fix: Spark plugs

ORIGINAL: Lizardbreath

If you are getting 11 MPG that means you have a heavy food and something wrong with your car. My car gets 17MPG and it's a cobra and I romp on it only every once in a while. I would do the following:

1. Change out plugs (IF it has been more than 25k miles)
2. Change oil
3. Change fuel filter
4. SEAFOAM
Well, if i have time, ill buy some plugs thursday, and toss em in. I drive the car normally, dont floor it, and drive the speed limit. I havent revved it once this tank.
