I supposed the only way to accurately measure it, is to calculate the number of gallons at the gas pump delivered, divided by the # of miles traveled. Say from a FULL tank to the low fuel light on. Repeat a couple of times to check precision.
If anyone is traveling soon, please post results.

I have a 1999 Corvette. I have used my own calculations, data from the car's computer, and yes I have gotten 33 mpg. My Vette has a Vararam air intake and a B&B exhaust with 4" tips. You need to take into account that a light weight car, a lot of air in, a lot of air out, with high horsepower. The car breathes well.
