I have Gas

Would putting a lil of 100 octane just be a waste of money. With the Cobb Access...I always use 93...Just Curious...

Thanks

Unless you have a tune that would take advantage of the higher octane, I would say a waste of money. Besides, what's just a little bit going to do besides maybe clean your injectors a little bit and raise your overall tank to like 95 octane.

hey cleaning your injectors isnt a bad thing

extra knock threashold is worth it to me :) but really depends on what you are trying to do.

I usually toss in a 2 or so gallons before I go run auto-x... the extra knock protection and tiny little bit of timing advance I could get from it helps when the intercooler can burn your hand off after a run.
