i hate oxygenated fuels, in NJ we have then from oct. 1 to april 30
next year NJ will not have them, or so i've heard
the first day i put the crap gas(oxygenated} in, i couldn't chirp my tire.
i have a 318 with 350 rear diff.
when the computer adjusted i was fine.
this took a couple of days
then i was leaving lines in excess of 120 feet!
