great for my hd.

It work's

use this in my DD2 go kart but don't see the difference

On several occasions I have had to refuel with lower octane gasoline and then ride through mountains. The pinging was especially bad and my bike basically lost acceleration. One of my friends suggested your octane boost. I tried and performance back where it should be if not better. I actually believe it is better. Now, I always travel with a bottle on my bike. Great product.

This octane boost is fantastic. My 2013 Road Glide Ultra runs so much smoother, quieter, and more powerfully that it seems to be an entirely different motorcycle. With 91 octane being the highest available in my area, this octane boost has proven to be a wonderful solution to the ping pang ting tang that had made my rides less enjoyable. Thanks Amsoil!

Not just those times when you feel the engine sputtering from bad fuel, but also when going on long trips & knowing there may not be Premium available.

Put the stuff in my tank, and it woke the bike up. Runs like a million bucks.

Use mostly when I stop for gas at unknown stations. It works!!

I only run ethanol free gas in my Harley, problem is though that the only ethanol free gas that I have acess to only comes in 87 octane. Buy using this product, I know that I'm getting enough octane to prevent pre-detonation.

All your products i've been using Amsoil for going on 17 years and my motorcycle and always shifts good and always runs good I never have any problems it runs cooler a number one product as far as I'm concerned

Really helped stop engine ping during low rpm acceleration.

I tour extensively throughout North America on a Harley-Davidson CVO Ultra Classic. The 110 cu. in. engine has been modified to improve its performance, primarily to increase mid range torque, essential for the fully loaded / two up riding that's my norm. My route preference is always far off the beaten path, as far from the interstates as possible. Quite often, I wont find the premium gas that my bike needs or the octane of the purchased fuel is questionable. AMSOIL Motorcycle Octane Boost solves the problem. Simple, pour one into tank, motor is happy again, we ride on!. I don't leave home without it, beats all the others out there!

I bought a bottle of this and used it in my BMW motorcycle recently this year. Honestly you really can't say much using only one bottle so I don't know what to say. Unless you had some kind of testing equipment and did an actual test on whatever you were using it in I don't know if you would notice much. It's kinda like taking supplements unless you do it for awhile and then quit you may notice the difference but it is very subtle.

I use this product on my motorcycle and pick up and like this product better than anything else

Awesome stuff. Could tell a difference.

Used several bottles of this product and noticed no difference in how the bike ran.

Love this product in my Harley!! Run aftermarket parts with a Dyno tune and my buck love the additive

I live in Las Vegas and work in California and their fuel there sucks. Tons of watered down fuel from all companies. I use the octane boost while I'm there and it extends my mileage. I ride a Goldwing and I'd get terrible fuel mileage, but 1 bottle of boost and I'd get about 25 more miles to the tank.

I've used this product mainly just to see if there was any noticeable improvement in performance.. It did make a difference but with the price of Premium gas which my bike requires, there wasn't enough to add it very often.

I use this Octane Boost every time I fill up my Road Glide. The very first time I used it, 5 years ago, I could immediately notice the increase power from my Screaming Eagle engine. Never fails to give me superior performance.
