I've been using this oil in my rx8 for a few years now and it is great for premixing with fuel and in the oil injection system. Rotaries need fresh two cycle oil and this stuff works

I have used other higher priced synthetics and this Dominator from Amsoil burns cleaner, gives great protection and costs less! Been running in cr500af for past couple months, will buy again.

I have heard of Amsoil a long time. This is the first time I have used it. Seems like really good stuff without breaking the bank. I bought a 1 year membership and bought a bunch of supplies for the start of desert season.

I live in fl where it is hot in the summer. Oil breakdown is paramount on my harley's engine life! With the viscosity and proven quality of Amsoil 60 wt oil it has served me and my ultra classic bike like no other! Oil changes every 20k makes it well worth the couple $$ more for Amsoil than cheap competitor oils. Make it your own choice like i did for everything from weedeaters to my truck!

I use the dominator pre mix oil in my 2015 Ktm 250 xcw. I mix it at 50:1 with 91 octane pump gas. Have had no problems with it and bike runs great at all temperature ranges. I race hare scrambles and enduros as a B rider so I am putting it through it's paces and it has performed great!

I have used several other racing oils and have had issues with all of them. Maxima Castor 927 came out of solution when the temperatures dropped. Klotz required regular remixing. I started using Dominator after my last piston change. That was 2 years ago. I haven't bought a piston since. It mixes easily. It stays in solution. The red color makes identifying the fuels easy, especially when the tags fall off the cans...

Used in a 2017 YZ125 ..... piston wasn't changed until after 30+ hours and it looked like new. Something must be working, I'm guessing the DOMINATOR 2 stroke oil

Great 2 stroke oil. Burns clean and keeps my bike running strong. Going on 105 hours on the motor with no issues. Run it in everything 2 stroke I own

Have tried other oils and had loading issues along with fouling plugs. I switched to the Dominator 1.5 years ago and have not fouled a plug since.
Reviewed by Motomom:
We as a family use this in all our 2 stroke toys. My boys race a KTM 50 pro senior & a YZ 85. They run great on this & it's honestly our favorite that we've tried in them. The only thing is the KTM does smoke & we do mix it to the ratio called for.

I use Dominator 2 stroke oil in my dirt bike because that's what the previous owner used at it works great. I've hade no issues and have kept used because of that!
Reviewed by Jones Racing:
This oil is the best that we have found to use in our 2013 KX 100. While doing our tear down on the bike, there were no scuff marks on the piston, like we have seen with other cheap oils. Would recommend this product to anyone looking to improve the quality of your 2 strokes.
Reviewed by Mc:
I am a landscape contractor and run a lot of 2 cycle equipment. I switched to this oil because it costs less than half that of name brand synthetic mixes and it works just as good if not better. I buy it by the gallon which is more practical than the single use bottles. No smoking or fouling of any kind

I love this 2 stroke oil. I've used oil that would settle on the bottom of the tank and you have to do the front brake shake. This stuff mixes and stays mixed. It smokes just enough and has minimal sludge on the pipe. I disassembled my top end after 60hrs and it looked good. Gonna check it again at 100hrs and do a top end if needed.

Dominator is the ONLY oil that we use in our 2 stroke MX race bikes. I maintain a fleet of 6-8 2 stroke MX bikes that our family races. Piston and ring life is longer, oil burns cleaner, less pipe "spooge", fewer fouled plugs and it is my belief that this oil does not break down as quickly when left mixed with fuel in a tank or fuel jug for a period of time.

Never had an engine failure related to lubrication deficiency and we've been using Amsoil Dominator for a long time. It's the only two stroke oil that gets used in our race bikes. It's hard to argue with proven results.
