Customer Ratings & Reviews

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.

I ride an Indian Pursuit motorcycle. Anyone owning an Indian can tell you that the engine rattles and pings awful without the highest octane available. Many other motorcycles need this as well. This does the trick!

GREAT PRODUCT THE PRICE IS TOO HIGH .

Ran it in a tank and have been impressed, no knocks pings, seems to run smoothly and quieter

Recommend using a few times a year. Works great!

Makes my 07 Harley run better

The only additive I have ever used where I can tell a difference in the smoothness and performance of the engine 114 powered HD Road Glide I use in every fill up!

Use this when making long Road Trips on the Bike, like Going to Sturgis SD. Even though you stop at Neme Brand Gas Stations you never know what your getting and this stuff is like performance in a bottle for fuel problems and performance

Great products

Placed in bike and felt a smooth bike. I do not hammer my machine, however this definitely improved throttle response. I am a believer!

Runs better no engine noise

Does help engine run smoother and better fuel economy per tank

helps a bunch and is noticeable . increase in throttle response and pull

Noticed the difference right away on my 2 stroke.

I bought a box of the stuff and took it on a 5,000 mile motorcycle trip over 2 weeks with four other riders. We have "Gas Mileage" wars . . . comparison of fuel used tank to tank with miles varying from 150 to 230 in our Harley Davidsons. I was sneaky about it . . . . snuck it into my tank when no one was looking. Comparisons of fuel efficiency were inconclusive. Not enough to write about. There was one place in the Nevada desert near Area 51 where they only had 87 Octane and it was expensive. We each bought about 2 gallons, enough ensure that we make it to Cedar City. I opened a bottle and shared it with everyone except on that turned it down. None of us (even the guy that turned it down) commented about any issues with the gas. So I don't know. I feel sure that there are lab experiments that will show a difference.
