Klotz Higher Octane Booster Fuel Treatment – 1 Gallon KL-628

Great product. Only product that works in my car fully modified turbo modified Hyundai turbo. As soon as you put your foot down you feel the difference big time

I use this to boost ethanol free 90 octane gas and it is also a stabilizer.Works great, my small engines always start right up.

I’ve used it for years. Can’t say I get more power but it smells so good. I use it in everything. Great treatment for stabilizing fuel.

US premium fuel just meets the minimum fuel octane for my KTM. I bought this for peace of mind to make sure thefuel met and exceeded the standard. The bike runs cooler and the fuel is stabilized in case of storage. I use 2.5 ounces per gallon. I believe the bike runs more smoothly, and if I had tested it probably has more power.

I have a couple of high compression muscle cars.This is the real thing Tetra Ethyl Lead!Just follow the simple instructions of the container.May need to run a few trial runs to get the appropriate ratio for your application, but that should be expected.

This is the most cost effective way to make HP gains on a tuned car. Saves me a lot of money of race fuel.

Used this Octane Booster in my KTM enduro and turbo Harley with awesome results. Good cheap insurance to avoid detonation and added lube.Works much better than VP Fuels Octanium which formed soot on the plugs and caused slight misfire.
