I did a little research and found that 1 gallon of gas weighs 6 pounds (750 g).

Running with a 1/4 tank of fuel is roughly 4.25 gallons which weighs 25.5 pounds.



Steve: have you been factoring this in CarTest?

Right!! Full tank of gas 18.5 gallons * 6 lbs - 111 lbs
1/8th tank of gas * 6 lbs - 13.9 lbs

Coupled with any weight reduction, rear trunk mat/carpet, ps seat, spare/jack/tools, and you can see how this freemod is bad-a$$!

I always try to do it where I go to the track with 1/4 tank, but it always works against me

Cartest has driver weight and fuel weight separate from the curb weight of the vehicle. Default settings are 160lb driver and 30lb fuel + curb weight I believe.

So do you think they already factored in a 1/4 tank of fuel with the 30 pound setting?
