To fuel or not to fuel that is the question???

Drag racers, heavy or light tank? Or as JonB says, does the year matter? How much weight is a full tank?

Jet fuel is about 6lb/gal. Gas is probably a little less.

6.17 pounds per gallon @ 60 degrees fahrenheit

A full tank might cost you a tenth over a low tank.

Low tank, unless you are having major traction problems. If you are, the extra weight, placed over the axle might actually help you gain traction. You lose time though. I prefer empty. Race teams rack their brains to figure out how to lose OUNCES! They sure don't add a 15 gallon fuel tank over the wheels to help them stick!
