Best octane booster
I have been using Klotz octane booster for a few years now. It does exactly what it says. I put 16 ozs into my gas tank after each fill up. With this ratio I get 93 octane. This works very well for my modified turbo car. The only thing that I do not like is the spout. No matter how you angle it for a pour, you will get runoff on the container. This only happens with the gallon cans.

Good booster. I add 16 oz. to 8 gal to get 96octane and I can set my advance to 38 total only $6 instead of $20 for 2 gal. of race gas.

Octane Booster
Just recently added to my fuel. It was recommended by a friend. I believe it will improve performance in my antique car.
