Tried 88, can't really say if I saw a difference at all or not.
i really didn't think 87 => 89 would make that much of a difference, but for only $0.10 more a gallon... i thought why not try it at least once to see?
i've been lucky to have a non-finicky dct which just got smoother as i put more miles on it, but switching to 89... i was looking at my tach and saw the rpm's changing when my car shifted... but this time, i couldn't feel it shift. now with the miles i put on it, it already shifted smooth; but if you paid attention you could feel the shifts.
89 in the tank, i just couldn't feel the shift / made the vehicle that much smoother. i'm impressed. as long as gas keeps falling in price, i'll go with 89 for the time being. using 87 wasn't BAD, but i like the difference i see with a tank of midgrade 89.
