What is the best octane booster

[YVES1M]

Hi guy's, what brand of octane booster do you suggest for my baby? I live in montreal and the best gas is petro canada 94..

Thanks

Do you have E85 there?

Most octane boosters do very little. When they say they bump up the octane one or two points... then actually mean 0.1 or 0.2 octane points. NOT 1 or 2 octane points.

Go to your local speed shop and order yourself some higher octane gas or they will tell you what works best for what you're trying to achieve.

Truth . . . should be a crime to misrepresent a product like that.

Don't put that trash in your BMW.

Many people experience the opposite, I run it everyday and no problems yet.

Its not that they are experiencing the opposite, its just that it hasn't happened yet. The entire gas system isn't built to withstand that much corrosive ethanol, the seals in the pump and such will degrade over time and eventually fail. It just may take a very long time, but it will eventually happen.

Torco Accelerator is a race fuel concentrate. That is the only thing I would trust to bump up the octane...

Terry at BMS uses NOS octane booster with MMT which apparently is good enough to raise the octane from 91 to 93 in Cali. Cant say ive used it though. Only stuff he recommends...
