Predict my fuel economy. 530 mile road trip coming up
Hey folks I have a 530 mile or so road trip coming up. Im driving to Fairfield CA from San Diego CA
I've done this trip on my 2 other cars.
On my 1998 Buick Regal GS with a 3.8 Supercharged V6 and some mods I did a personal best of 31.85 MPG. The EPA rating for this car on the freeway is 25MPG.
On my 1999 Chevrolt C2500 Pickup with a 6.5 TurboDiesel bone stock I did a personal best of 21.36 MPG. The EPA rating for this truck is 17 MPG Highway
So now I'm going to try this out with my Corvette. My current stat is 16.68 MPG 18.6% below EPA combined rating. The EPA freeway rating for the C5 is 25 mpg,16 city and 20.5 combined Heres my current gaslog
My car has a 6 Speed with Shorty headers and an intake and dynoed at 331 horsepower to the wheels. I intend on going 69 MPH most of the trip. Im going to behave and resist the temptation of going WOT because Im a stat freak and I want to bring my stats up..
Its always fun seeing how high you can go over the EPA rating. So on my Regal I did 6 MPG better then the EPA rating and on my C2500 I did 4 MPG better then the EPA rating.
So predict my MPG for this trip . Like I said Im going to stay at 69 MPH and at that speed the engine is spinning around 1500 RPM or so
