We use and recommend High Performance Lubricants that are custom blended for us. We are not chemist or engineers but we do know how to run our dyno’s and run track tests, and that is where everything ultimately needs to be tested.
The tests began as a result of looking for a good break-in oil. We found one as it sealed the engine quickly, had more vacuum and consistently showed a 5-8 hp gain in a 1200hp 8000 rpm engine.*
We saw the same results with 5w30 race oil that has a slightly higher film strength and lubricity.
Our testing now shifted to the track. We used what an engine that I consider to be harder to adequately lubricate, a 632 Wet Sump. We tested two crankshafts and two different configured oil pans. We got the best results I have seen to date. This makes me feel confident in using and recommending the product that has been blended for Reher-Morrison.~ David Reher
*We now use this break-in oil in all of our engine builds.
