Fueling at single hose pumps means getting a hose full of regular gas before the 91 Octane fuel comes out. Adding Octane booster to my 6-gallon tank makes sure I'm getting full Octane or even a bit more into the fuel tank. I put it in every other tank full, and I do believe the engine runs smoother with better throttle response. I'll continue using it and the Cetane booster for my diesel pickup.

I could not run ethanol-free gasoline without octane boost. Thank you!!

I have only used this product In my older Atv. The bike is a 2003 and was idling rough and had poor proformance when cold. The 1st tank of fuel i seen an incredible improvement in the bike idling and driving . Bike doesn't even need the choke when first starting the bike. Totally amazed !

My bike requires high-octane fuel, which I can't always find in rural areas, so I grabbed a bottle of this for those times I can't get what the bike needs. Haven't used it yet, but it's good to know I have it when the only thing I can find is 87 or 89 octane. I haven't gone wrong with any other AMSOIL product, so I'm counting on this in a pinch.

Premium fuel isn't always available at fuel stops, knowing that adding the octane boost to a lower octane gas makes my Harley run smooth

Used it on my 2007 Harley Davidson Street Glide. Seemed to work well.

Whenever you're ordering oil for next oil change, give this little guy a try. Good combo to boost 87 ethanol free to 91, instead of mixing gas levels to achieve perfect octane

AMSOIL Motorcycle Octane Boost it works..........

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
