KlotzHigher Octane Booster Fuel Treatment – 1 Gallon KL-628

I run this in mt 2022 maverick x3 turbo RR. There are times when you just can't find premium out on the trails and my tune requires 93 minimum. I also like it keeps fuel from going bad and the fuel mileage has gone up. I can tell it's raised octane because I can see that there is no timing being taken away when running it but when using regular 93 it will start to cut timing at certain loads and boost. One negative is it sucks to be behind me on the trail it gives off a soapy racing fuel smell that's not great. Trust me I love race fuel but this stuff will really start to bug you. And there must be an upper lube in it because you will feel like you have oil on your face after riding behind someone running it. Overall great product.

I’m really impressed with how well this product cleaned the pistons in my engine. After using it, the performance improvement was noticeable. The engine runs smoother, and I feel like it’s more efficient now. The application process was simple, and it delivered results as promised. Highly recommend for anyone looking to maintain engine cleanliness and performance.

I have been running Klotz octane booster in my high performance Harley Davidson 131 engine for several years now. I only use it on occasion. I add 3-4 ounces to a full tank of 93 Octane. When I use it I get better throttle response and the engine runs much smoother at all speeds but most noticeably at high speeds on the interstate. I recommend this product.

Works great!

I’d heard from a very respectful publication about this product, that it’s one of the few products that really boost the octane. I live in a state where the gas (methanol blend) is unbearable to a carbureted engine. I’ve purchased 100 octane fuel and have tried multiple high octane gas stations, 91 octane is what most gas stations have. I’ve read that the additional octane in higher octane fuel is often achieved by adding, what, you guessed it, more of the additives, not more gas. The gas here just seems to burn with my classic car like it has a lot of empty calories. It also starts to boil very easily, once heat soak hits the engine bay it’s over with. I’d heard from people that using a lower octane fuel won’t have as much additives that they add to today’s gasoline such as butane. I tried using the 87 octane alone in my classic car and detonation occurs after the engine has been running at operating temperature for a while (gas starts to boil aggressively at very low temperatures). I’d also read that Klotz also helps counter the above mentioned side effects of today’s E10-E15 gasoline. Klotz seemed like the perfect solution. So I decided to fill the tank at 2 ounces per gallon with Klotz and 87 octane fuel as suggested 16 ounces when I’ve got the tank 1/2 full, and then the last 6 ounces to top off my 11 gallon tank. I really expected no change, another one of those hopeless experiments I thought. I could tell when the last of the higher octane pump gas had consumed itself out of the carburetor float bowl and the new mixture started coming in, I noticed a definite, significant difference in the combustion, it reacted to the throttle much better, it felt like a longer burn time, like what my engine has been asking for, like gas is supposed to feel like! It also quieted down the engine (as well as electric fuel pump) as a bonus. My next thought was I wish I had a 30 gallon drum of this stuff! I just have to be careful putting it in my tank because it will eat the paint if spilled (I just use a funnel) It doesn’t cut everything out from the side effects of the E10 gas, I don’t think anything can but it has made driving my classic car enjoyable again and that’s enough.

I have a 440 Mopar big block in my Plymouth Duster. It has 11.5 to 1 compression and 210 psi cranking pressure. When I first got it running I ran 93 octane pump gas. I heard a little bit of ping when I rolled into the throttle and it dieseled a few times when I shut it off. I tried Turbo 108 octane booster from the auto parts store and the only way I could get it to stop the ping was to mix it at high concentrations and it was not cheap. I did some research online and discovered that the Turbo 108 and other brands the parts stores sell only raise the octane by points of a number. That means they raise it like .1 so the 93 octane becomes 93.1 unless you dump a lot of it into the tank. The Klotz and other premium boosters raise it by whole numbers. Anyway I mix the Klotz 1 ounce to a gallon and it works perfectly. At $52 a gallon, each ounce of the Klotz is only about 41 cents so it only adds 41 cents to a gallon of fuel. I've been running my car hard for two years now and have had zero failures. No ping and no dieseling when I shut it off. Also worth noting, the pump gas I run has 10% ethanol in it. I have had no alcohol related problems with the fuel system and I store it all winter without draining the fuel. I frequently remove the fuel bowls for jet changes and the carb is spotless inside. I highly recommend the Klotz octane booster.

It sure makes my motorcycle run better. It seems to keep the injectors cleaner as well.

after mixing product car was knocking and set engine light, good price but not for the running issue, remember you get what you pay for
