Customer Ratings & Reviews

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.
