10W-40 Racing to Maximize Horsepower
DOMINATOR is formulated with proprietary friction modifiers to reduce energy lost to friction. It delivers maximum horsepower and cooler engine temperatures, promoting
improved lap times and longer-lasting components.
- Delivers maximum horsepower and cooler engine temperatures, promoting improved lap times and longer-lasting components. When everything is going south on those last laps, the driver with AMSOIL keeps it full throttle not worrying about the temp gauge while the competition’s engines go into thermal runaway.
EXCELLENT ALL-TEMPERATURE PERFORMANCE
- Low pour point offers excellent startup protection and provides less drag when the oil has not reached operating temperature.
- Maintains superior film strength in extreme heat.
- Thermally stable synthetic chemistry resists the effects of intense heat common to racing engines to provide reliable protection for the duration of the race.
See the product data sheet for full details.
If you are racing to win AMSOIL Dominator is KEY. If you are performing engine tests you want the engine to squeeze out all the power possible w/o added drag. The differences per Gail Banks is in the magnafluxing tests after the run! It’s that visible and drastic.
Commercial Availability

racing oils offered only to NASCAR* teams. DOMINATOR Synthetic Racing Oil is already formulated to a high level of performance.

The same DOMINATOR Synthetic Racing Oil that is used in the engines of AMSOIL corporately sponsored racers, including Bryce Menzies and Brad Lovell, all these blokes – is now available to everyone.

- Asphalt late model
- GM* crate late model
- Dirt late model
- Marine

Alternate 10W-40 for street rods and classics
If the car is not strictly for track use you might find our Z-ROD 10W-40 product the better choice. Especially great for cars that spend a good amount of time in storage as it excels in the rust and corrosion department. It’s a high ZDDP oil designed for 10,000 miles or 2-years.
AMSOIL’s Racing Oil Line Reviews
Great racing oil
By JAMES, a Verified Buyer on May 24, 2024
This is the oil I use in my high compression 565 big block chevy for track days. This is definitely the oil to go with if you want to protect your race car while you beat on it going down the track.
Proof is in the pudding
By LARRY, a Verified Buyer from Texas on May 17, 2024
Recently made some changes to my 532ci. BBF and was going to replace the rod bearings while having it apart. After 3 seasons of 200’ mud drag racing, the bearings still looked new. Ended up putting them back in and looking forward to another race season, thanks to Amsoil Dominator Racing oil!
Great for racecar (Ralliart 2010)
By BRET, a Verified Buyer on April 12, 2024
Great oil. No issues been using it for 7 + years. Perfect for how the engine is built to have good oil pressure at idle.
Great for built engines!
By TRAVIS, a Verified Buyer on December 20, 2023
This is all I’ll use! When you have thousands dumped into a high horsepower build with with very tight specs and tolerances, I come to AMSOIL for my oil needs. The high content of phosphorous and zinc also help protect the investment. Oil is crucial to any build, no sense in going with anything but the best!

Keeping my race car running high RPMs with confidence. I have been using 15-50 for 2 years since engine rebuild. No pinging, oil pressure holding strong.
