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.

Noticable power gains. And keeps carbs and fuel system running great

I use this in atv's and in my truck while hauling trailers. Gives you a bit more bang when you need it.

Eliminates spark knock with my trifecta tune

I just started using it. But the P.I cleaner is the best.

DOMINATOR Octane Boost works very good I like.

Generator runs so smooth starts up in one pull even when it’s 20° in the snow and high altitude. Thanks Amber for an excellent product.

Put this is my 1995 Yamaha kodiak 400 it has been running a little rough not it’s smooth as can be. Thanks Amsoil!!

This will help your engine unleash the beast that lives within

DAMM GOOD WITH THE GAS

I saw this on the Engine Masters show, sponsored by Amsoil and tried this in a high performance 502 cu. in. engine that runs on pump gas. Don't know if it really increases the octane number but it makes a notable difference in engine performance. Starts quicker, idles (big cam), runs much smoother, and stopped the dieseling completely. Just getting the engine to idle at 7500 feet altitude is worth the the cost.

I have an nguage reading alcohol content and it didn't change any percentage read through the vehicles computer readings. It is possible 1 bottle wasn't enough for the 36 gallon tank on my vehicle. I'll test this theory at a later time.

Gives me the edge on my buddies that won’t use it. Love it in my summit 850

I have been using AMSOIL products for about 40 years. They have always had superb lubrication products for whatever your application is. Recently I was introduced to the Octane Boost. I have my 2019 Mustang tuned to a bottle added to almost every other tank. Man what a difference. Thanks AMSOIL.
