Gumout 800001706 Octane Booster - 10 oz.

It works great.

Octane booster works good. It's difficult to get it all out of the bottle though when your gas cap is in your bumper behind the license plate.

Great value

Works great, solved my jeep engine knocking and smoothed out the performance.

Good

Works great for using 87gas, mmt additive and TINY bit of synthetic 2cycle outboard oil, runs EXCELLENT, although unit cost of all that might be close to using 92_94_gas, oh well.

Gracias

This really helps my old Toyota Camry run better. For the past couple of years it's been knocking a lot with regular gas, thus increasing oil consumption in my old engine. With this product it's increased performance and almost eliminated oil consumption all together as the engine rarely misfires upon acceleration. I also noticed a huge increase in performance in my old Camry. I recommend this to anyone who has a gas car new or old.
