As for the 89 octane I honestly have no clue, every car ive seen is either regular (87) or premium (91), however I have heard the same idea that the higher octane will clean out your engine/tank and mainly because it will burn a little bit cleaner/hotter. Anyone else have some feedback on this?
Its pretty much the same one i have more or less
for the gas, i seem to get around 27-28 city & highway if i'm not WOT it all the time compared to my 24 on 87. but it does feel like the throttle response is better and i don't have that sputtering when im engine braking in 3rd or 2nd
