I'm not really sure of the performance increase by use, but I like what I read about what it is supposed to do and I trust Amsoil to deliver.

Reviewed by Phil from Canada:
I own a high performance snowmobile, so I'm always cautious when i fill up at the pumps as I want 100% premium fuel. Not always the case at gas stations in northern Ontario. Fuel quality seems below the said standard. So I always carry a bottle or two in my tunnel bag to use to bring up the standard that I am always looking for. Cheers

I used to use the 104 Octane Boost/Lead substitute.
After hardened exhaust valve seats in a 10:1
compression 340 small block, I use this instead.
No ping with advanced timing.
Reviewed by Self proclaimed Amsoil fanboy:
The octane boost is self-explainatory if you are running high comp ratio. This product also has lead substitute if you have older car without hardened seats for modern unleaded gas. Also, this is in a carrier of diesel fuel which I can't confirm for sure but, I suspect it suppresses the vapor lock problems of modern gas.

I have a 70 Chevelle with a HiPo SBC. Engine has 10.25/1 compression and a mild cam. I used to have to blend race gas with 92 octane to keep it from pinging/dieseling. Race gas is $10/gal. 1 bottle of Dominator treats 15 gal of 92 and no more problems for a lot less $$$.

I use Dominater Octane Boost every 2-3 tanks of regular 87 octane gas. My 65 SS Impala runs noticeably better with it.
Reviewed by Lipster:
I have used Amsoil products for over 20 years and have always been happy with the results. My recent purchase of Octane Boost has proved to be no exception.
I used it in my 2003 Harley Lowrider this weekend and honestly, the result was something that made me not want to bring the bike home. Smooth application of power especially at low RPM and just taking off. Engine ran noticeably cooler and it may sound crazy but the exhaust note was slightly different. There was more........growl to it than before. That I noticed but did not expect.
On the highway and climbing hills the increased performance was quite evident.
Now, it was not an engine overhaul, and nothing magic, but for a noticeable improvement in overall performance give Dominator Octane Boost a try. I am certain you will like the feel.

I use the octane boost when I want a little more performance in whatever vehicle I choose. I use it in my supercharged truck in case I can't find the minimum 93 octane it is dyno tuned for. I use it in my Screaming Eagle Stage 3+ Harley Davidson Ultra Classic Electra Glide, which is also dyno tuned for 93 octane, when it can't be found in a Smokey Mountains podunk town. I also use it in my Acura TSX on occasion. Awesome stuff!

Pump gas can sometimes leave more to be desired. I run 93 octane in my vehicle to get the cleanest burn that I can (despite what some articles might say). I used this product to run with the Amsoil Performance Improver P.I. fuel system cleaner to optimize my results. I have had an increase in my fuel milage as compared to before treatment (my fuel milage wasn't bad before and is now better). I recommend this product by itself or with Performance Improver P.I..

I often use Amsoil Octane Boost products while driving though certain Sates that have heavier Alcohol content in their gasoline. It greatly reduces pinging and adds power responses. I also will use the Octane Boost in the mountains for the basically the same reasons. It's a huge improvement in performance.

Living in Washington State, I don't ride my 2014 BMW R1200RT-LC year round so I leave it in the garage hooked up to a Battery Tender, and the gas tank filled with Pure Gas AND 3 oz. of Amsoil's Gasoline Stabilizer. Every summer when I start up my bike there is little hesitation, and the engine settles down to a steady idle. Riding that first tank shows no problems or misses in any RPM range, though I don't get the full mileage of 300 miles, but with the very next tank of gas things are back to normal.

I trust Amsoil products, after using them for so many years. Our gasoline gets delivered by barge and then trucked to us. It's always got visible crud in it and I have to put it through a filter first. As soon as I get my gasoline, I filter it and add Amsoil Gasoline Stabilizer. While others in the area have had numerous problems with 'bad gas,' my gasoline has never let me down. It gets used in my Stihl saws, Echo yard equipment, my Polaris Ranger, my portable Honda generator, my Ariens wood splitter, etc. Never a problem.

I recommend AMSOIL p.I. cleaner to anyone to clean the engine combustion chamber and fuel injectors or carburetor of a gasoline engine. I've used this exact product on a recommended vehicle maintenance schedule for many years. There is a very noticeable difference to prevent engine from knocking by cleaning the carbon from the combustion chamber. I use this in a Ford truck, Pontiac car and a Kawasaki motorcycle. Highly recommended above any product of its kind is AMSOIL p.I.

Before I started using this product (P.I.) my 2006 Toyota Tacome was getting about 19 - 20 MPG. When I use this product it moves easily to 20-22 MPH. It must be doing something good. However, I must admit to using exclusively Amsoil Signature oil.

Re: OWNER
DOMINATOR Octane Boost is designed for off-road & racing application and therefore not recommended for use in vehicles equipped with catalytic converters.
To increase performance of a catalytic converter equipped vehicle, we recommend AMSOIL PI - Performance Improver fuel additive to clean combustion chambers, intake valves and fuel injectors.
