Let me see some math 250 miles per tank vs. 400 miles. That is a differance of 150 miles per tank. Now I am not sure of you tank size but it is what a 15 gal or 20 gal? On a 15 gal tank 93 octane gives you a boost of 10 miles per gallon. On a 20 gal tank that is a boost of 7.5 MPG.

250 miles/15 gal = 16.6 mpg
400 miles/15 gal = 26.6 mpg

250 mi / 20 gal = 12.5 mpg
400 mi / 20 gal = 20 mpg

Impressive numbers. I didn't use a calculater so correct me where I am wrong.

Cheers,
RJ


RJ I am sorry but the problem here is you did not use Georga addition..
I agree it is voodoo gas milage if you don't calculate it exactly on every tank.. Guessing don't get it.
