I use this in my antique 1969 BSA Rocket 3 high performance Café Race motorcycle. It helps a lot!

I use this product in an engine without hardened valve seats. all upside no downside. easier starts, better acceleration. very happy with this product.

Use this in a ATV. Great results!

IN PULLING TRACTORS

I use this product always in my snowmobile

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 use this in my harley trike help with pickup and on take off and while i pull my dog trailer helps alot

There is a substantial difference for almost two fuel fill ups once applied.

Put it my explorer every 2 fill ups

Use in Audi 2018 Q5. Really helps. FYI, use with PI every now and again. Note: I live in Boulder Co. at this altitude this product seem to really help performance.

I use this in a 16 Focus ST when I can't get 100 octane for track days. Seems to work just fine.

like the product. does whats its sapose to. will keep purchasing

I use this product in my Harley, ATV, Snowmobile. I can tell the difference in power.

Noticed a better throttle response in my sleds and dirt bikes. Great stuff

Extremely Impressive,Buy One Twice A Year.Which I Could Catch A Break On The Expensive Shipping & Handling.

Very good product. I use it exclusively in my snow machines. They run top notch with the added octane boost.

I use this octane booster in my 02 wrx and it works wonders. I always buy a case and keep them on hand. This is a life saver if you have pumps that have only 89-90 octane ratings.

I use Dominater Octane Boost every 2-3 tanks of regular 87 octane gas. My 65 SS Impala runs noticeably better with it.

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.
