Customer Ratings & Reviews

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

I have been using this for sometime now. It definitely makes your throttle more responsive. I recommend using it.

Got a late invitation to ride motorcycles to Sturgis South Dakota for the bike rally. Had one week to get oil changed and get everything together to go. Ordered oil change kit and transmission oil, got it in a few days in time to change. My brother and myself met up with a group and rode 4300 miles round trip including the rides we did while in Sturgis. Will be ordering another oil change kit soon, since I’m close again to my 5000 mile schedule. Thanks for the quick shipping and great oil!

I use this for my cammed Harley M8, product works great!

Sometimes 93 octane is always available. I know using this protects my engine.

Works well and adds a little crisper rev to the engine

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!!
