Does anybody use a higher octane then 91

i try to run 93 if i can, but i fill up with whatever premium is there.

 

[Davisgtp]

do you see a difference

 

[Bio248]

i dont really scan often enough to tell a difference, but im sure ill notice when i switch to e85 since that is an octane of about 105.

93 here. That's all I use though, so couldnt compare it to 89 or 91.

93...unless I go to the track then it's 100

I always used 93 until I dropped major pulley size then had to use 93+ octane booster (that was in my 05). I did run 87 ONCE in my 07 and I got a misfire code plug 3 I went to clear the code and tried to start my car and it wouldnt. So I ended up changing them that night at autozone!!! lol. Im not saying the 87 did it.But I hadent had a problem but also ran 93 with 10% ethonl in it sooooo not sure if it was the gas or just needed new plugs!!! But if I was you I would run 93 as much as I could.
