Used this in a bike that had sat for years. Drained the tank the best I could, added fresh gas and the Octane boost, bike runs great and has great power

Incredible product that helps with the engine knocking in my HD 114 M8 motor. I use it at every other fill up. Amsoil quality for sure.

I tried, and the results were great !!!

The Motorcycle Octane Boost works great in itself. The problem lies with the adhesive used on the seal of the bottles. It doesn’t do a good job of keeping the fluid in the bottles. The ones I’ve ordered always have had a few that have leaked. AMSOIL as a company is great and they stand behind their products. When I brought the above issue to their attention, they more than made up for it. I was not expecting that. Above and beyond customer service!

I never settle for less than the best!

Great stuff and perfect sized bottle for for bike.

Will be buying again

AMSOIL always has everything thing I need and fast delivery

When traveling in areas where 93 octane is not available, adding this to your tank gives you confidence and peace of mind you will get quality performance and reliabity out if each tank of gas!

I’ve used this on road trips when a higher octane is not available at some stations. My Indian Appreciates the Boost!

I use the octane boost in my 2019 HD Roadglide. I upgraded my motor with a stage IV kit & improves the performance exceptionally by using regularly. Also is great for road trips when you fuel multiple times, you never know the quality of premium fuel on the road. My wife has a 2019 Spyder, which we use the octane boost in too.

Even though it's a Harley, getting more miles per gallon is always a plus

Getting more miles out of a gallon

super , good boost

I run this in my first tank of fuel after the winter storage each year and it runs like it has fresh gas in it from the pump after sitting all winter no hesitation or sputter any more

Been using Motorcycle octane booster for many years in my Harleys. Always ran more robust.

I always worry about getting good octane from the pumps for my bike and this really helps it run smooth. Great stuff.

It does what it is meant for, efficent

I just put a high-end remanufactured engine in my Mustang. This product rocks!!!

I use this to help raise the octane level in my bored and stroked H-D. Due to the poor fuel quality at some locations in my state, my bike used to suffer from detonation and at times poor throttle response. Since starting to use this additive, our bike seems to run smoother and stronger. I do recommend it.
