Customer Ratings & Reviews

Makes my twin cam run great

Helps the fluid operation of the engine as it moves through the gears. Always helps the gasoline that is put in the tank.

Good

Can't say i notice much of a change, but can't hurt either.. price is on point..

Haven’t had this product really long enough to give a good review but will definitely make a future one after using this product for a while

The best product i had ever used.

My motorcycle seems to like it alot. It runs much better.

First time to use it and I noticed an immediate difference in the horsepower on my XR200. I poured half the bottle directly into my fuel tank. No engine pings or knocks. The bike bike actually ran cooler!

Really helps when you're surrounded by Low Quality Gas Station's.

2017 street glide 91 octane and one bottle this bike comes to life

I've been riding high end BMW and KTM motorcycles for over 20 years. They require good fuel and that's hard to get in California. I keep these one shot bottles with me when riding, that way wherever I'm at I just add this to the fill-up. Amsoil makes the best products

Good

Awesome Octane booster

Could tell a difference run great

Use it regularly in the bike Wow what a difference No comparison to premium fuel

No pings and nothing but smooth running V-Twin engines with this stuff! Highly recommend.

I spend summers roaming rural Alaska on my BMW GS. There's no such thing as premium fuel in the remote ares. I always carry Amsoil octane boost.

I like to ride my Indian Challenger out in the back roads and some of the gas stations have a poor grade of fuel. This booster helps get the octane up so it doesn't knock.

Use it for my Son’s 2-stroke dirt bike. Noticeable power improvement. Great product!

Helps on those hot days on the Harley to stop the pinging
