ls1 really bad gas milage help
LOL... I get about 160 miles per tank right now and takes 12.7 gallons to fill it up. Getting about 12.5 MPG. I don't run it to the bottom. This is all around town driving and I do have somewhat of a heavy foot and the car isn't stock. I don't beat on it all the time though... get about the same mileage however I drive. Yeah, I'm still running RICH which is a MAF/O2 issue..
It's a MYTH... if you run out of gas , you dont have to take it to a shop to have the injectors primed. Fill er up and go.
But it's not good on the fuel pump to run it low. Since it's a submerged pump, the fuel actually keeps the pump cool. So running it low all the time, will most likely shorten the life out of it. It will NOT kill it instantly or anything like that..

Don't worry how many miles you get on a tank of gas. Fill it up,set trip meter to 0,drive till it shows 1/2 tank, fill up with gas and check mileage. That will tell you how many miles per gallon you are getting. I get 21-23 mpg runing around and 31 mpg on a trip.
You dont have to check at half a tank. Just reset the trip meter the next time you get gas. While the gas is pumping just reach in and press the button w/the key in the on possision. Now the next time after that, that you get gas, divide the milage by how many gallons you just pumped in. That willl tell you what your actual milage is.
