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

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

Awesome stuff. Could tell a difference.

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

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 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 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.

I purchase the octane boost for when I arrived my Victory Cross Roads in high altitude to assist with power and when I'm out on the road such as the trip from California to Oklahoma. octane boost works very well

Our bikes require minimum 91 octane fuel. I got stuck with having to use 89 octane fuel once, bike started to ping. Got home, added the boost, it quickly eliminated the ping and restored performance. I look forward to trying it on 91 octane fuel to see how it dose.

Good to have on a trip when you can not find 93 octane gas Works good no kinks or pings when used

Run this octane boost in My 2012 Harley Tri-glide for last 2 years, love it!!! My Tri-Glide loves it, too!!!

The octane boost helps my new Ultra run great! The individual size bottles are easy to carry in the saddle bags, just pour it in when I fill up.

I love this stuff! I've used it for all my HD motorcycles and it is AWESOME!

I ran this in my bike for the last ride of the season,full tank and alot of riding. The bike seemed to have a little more kick to it on the throttle and the bike ran smooth.I will be using this in my bike for now on. Great product
