Royal Purple (Molybdenum Disulfide)
As an Amsoil Dealer, I am partial to their product. But you have never heard me disc RP. I even told Mr.Hemi that RP may be better suited for a supercharger application than Amsoil. RP has always been performance oriented.
Another reason I don't disc RP is because RP is rarely mentioned in Amsoil comparison tests. That should tell you somthing. Amsoil seems to have the advantage in long term applications but RP seems better suited for extreme high-performance usage.
When it comes to apples vs apples, I do downgrade Castrol Syntec due to its partial conventional molecular makeup. Better than dino brands, but way down the totempole on the synthetic list.
How about it Motohead, has your company done any comparisons? Good or bad, Lets hear it.
