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.
Off the bat I will say that this oil is the best dang oil I have ever used in my High HP engines. It is the only oil that doesn't get beat to death by the engine. Also, having said that, it is the only oil that quieted the valve train too!! Its like a smooth sewing machine. My hot rod gets this oil ONLY, NO ACCEPTIONS. It runs smooth as silk and I have no issues AT ALL! AMSOIL certainly knows fluids on all levels. In my High Performance 1972 Monte Carlo (completely rebuilt by me and my life long friend, known as the "Magical Maestro Car Gnome") has all AMSOIL product in the vehicle, gear oil, transmission fluid and of course the 15W50. I am completely amazed how well their fluids works. Once I run out of bearing grease, I will begin to use that too, among more of their other wonderful products. It may cost a tad more, but I rest easy knowing my vehicles are well protected with this wonder fluid. So its well worth it and it lasts longer! if you have a heavy hitter, High HP vehicle like me, then this stuff is it! Don't even wait another second, just order it for your beast in the garage. YOU WILL BE PLEASED!
Yours truly,
Dan

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.
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!
Always have been using this oil for the Subaru since I bought it! Great product!
Bottom Line
Yes, I would recommend this to a friend.
