Best oil I’ve ever raced dirt track with. Last long time and does not break down. Hardly any wear on engine bearings over complete season.

Although I haven't been using this oil very long and I cant climb inside my engine to witness its performance, I have seen a recent video surface where an unbiased guy tests all the name brand oils on several fronts. Amsoil was #1 It beat out all the oils I had used in the past. I want nothing but the best for my 2013 5.0 it gives me a great piece of mind to know I'm using the best. Thank you Amsoil

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 Dominator in all my boats from pleasure boats at 7,000 RPMs and race boat turning 10,000 RPMs spraying Nitrous. Since I started using Dominator 2 Stoke Oil I have not had any (not 1) engine failure. I believe in this product and would not consider anything else.

Run in all my equipment and buggies. Cr500 in high Rev sand buggy, will not seize even with known air leak... should have seized but never did... amazing

I have 700 twin Polaris that I run on asphalt running 10.90 & 121 mp. Have been using dominator 15 years no problems at grand bend drag way . Ont Canada

I run this product in my race car that is powered by a 494 rotax snow mobile motor I never worry about problems evem in the heat of Florida or the severe stress running at Daytona Speedwlay. I have never had a problem and the motor always looks like new at rebuild time. Thanks Amsoil for a great product.

I use Dominator in everything from my chainsaw to my KTM 250sx. It helps engine stand up to the abuse of long races.

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.

My son races a Yamaha YZ 85 weekly. With a competitors oil I would change pistons every 6 weeks. With Amsoil Dominator 2 stroke oil I am on the oriiginal piston. Just two sets of rings.

Best two stroke oil product I have ever used on my race bikes!!!! Highly recommended!!

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.

Been racing motocross for 12 years and have been using amsoil dominator from the beginning and refuse to run anything else. We've had nothing but great performance and reliability with our bikes.
