lt1 - ls1 mpg differneces and why?
So I couldn't be more pleased with 20 city and 30 highway in the Pontiac. Only mods are a throttle body airfoil and synthetic oil. I do like to use a Ethanol Treatment. That darn Ethanol robs us of 10% power and 10% fuel economy. If you doubt it look online at Pure-Gas.com and find a station selling Ethanol-free gas. Give that a spin and you will see what I mean.
I dread the day we're all forced to use E-15.
350's back in the day got 12-15 a gallon so I am not going to complain about my Lt1's gas mileage I am going to get in it, lay rubber and enjoy the price of admission!
