I USE IT IN MY GAS.

I use this in my 33 ford street rod with a high compression V8. Since the car sits a lot over winter I use non-ethanol fuel in my local area. Most of this product is around 90 octane and pings if a octane booster is not added. The Amsoil product works great to solve that problem.

402 cuin Mopar Performance crate engine 460 hp 10:1 compression. Amsoil Octane Booster allows me to run 93 pump gas. Prior to Octane Booster I had to really expensive racing fuel.

Works well

I bring a bottle along when snowmobiling in areas with questionable fuel or when regular is all that's available.

You don’t always get 93 so I use this once a month

Great alternative to the gas station boosts and it's Amsoil. What's not to like.

We don't have many bugs other than their poop here in AZ, but we get nasty rain dirt and hard water stains from sprinklers. This stuff is a little more time consuming to use, but it works great. Try a can and you will not go back to the other window stuff.

i like it make my bike run cool and stop it from pining

My minivan runs faster.

No pinging at all. Engine runs nice and smooth.

Use in Shelby GT350. Can definitely feel a difference when added to a full tank of premium.

I have a tune on my Turbo S that increases my boost by 4 lbs, i ride at elevations at 8000 to 12000ft. this product is suposed to keep the engine running cooler and eliminate any chance of pre detonation. it makes 15 gallons with one bottle. No overheating or pre detonation issues at altitude.

Works well. I feel the difference.

Bought 1 bottle to give it a shot and see what would happen. Did feel, hear, and notice a difference. Will be buying more in the future.

I have been using the Amsoil Dominator Octane Boost product for the past year in my custom 70' Mustang with a 402R Roush performance engine based upon my mechanic's recommendation and I have been extremely satisfied with its performance. Definitely has eliminated the valve knocking sound as well as dieseling experienced with regular pump gas. I believe it has also slightly improved gas mileage, but I am not so interested in that as I am in power output. I do notice some improvement in engine output and the car seems to just run better overall. Highly recommend the product and will keep on using it!

My mustang was pinging on pump gas. I add a bottle of this at each fill up and no more pinging.

I use Dominator in all my engines. MC, Mustang, trucks etc. It does make a performance difference.

I have my 2019 Mustang tuned to this octane additive. A small HP boost on the Dyno.

Works wonders!! Great for cars that use premium gas, if you tend to pump regular gas mostly in them, good to add this to get rid of pinging on those really hot days.
