Octane Boost additive?
The highest octane gasoline I can find where I live is 91. Is adding Octane Booster harmful and is it even worth it or a waste of money? My biggest concern would be causing any damage to the motor.
I searched the forums but found nothing on this topic so my apologies if this has already come up...

87, 89, 93, and 100 which is racing gas and cost 6 dollars a gallon. I think adding octane booster is a waste of money. If your car runs on it with out knocks or stalling, then it should be fine. Higher octanes have detergents. Just dont use the cheap off brand gasoline. Use BP, Texaco, Shell, Chevron or Exon. They are all reputable. I stick with BP because Amoco fuel is rated #1. Atleast, thats what they say.

this is what led to my question. Chevrolet says to always use premium unleaded due to the high compression ratio which would lead one to think octane booster would give you a few more horsepower...

Octane surpresses igniton or detonation.
You want a higher octane fuel with higher compression to supress the tendency to pre-detonate.
You will not make extra horsepower with extra octane unless your car is tuned to advance the timing with that extra octane.

Don't use it. You don't need it. Stick with what you're using - 91 octane. Anything more and you're simply needlessly throwing (wasting) money into the pockets of the already rich gas companies.

So presumably the results should be comparable to real 89 octane at sea level.
