: Amsoil Series 2000 0W-30.....11.4 : Royal Purple 5W-30...........10.5 : Amsoil XL-7500 5W-30..........9.0 : Amsoil 5W-30................>11.0 : Royal Purple 10W-30..........10.5 : Royal Purple 10W-30..........10.5 : Amsoil XL7500 10W-30..........9.0 : Amsoil 10W-30...............>11.0 : Royal Purple 10W-40..........13.0 : Amsoil 10W-40...............>12.0 : Royal Purple 20W-50..........10.5 : Amsoil 20W-50...............>12.0 : Amsoil Series 2000 20W-50...>11.0 (1) The testing of 5w-30, 10w-30, 20w50 of the Amsoil outperformed RP with quite a number, but how it ended up with a marginal number in overall test?
(2) Amsoil's 10w40 outperformed RP's 10w-40 in every test, but how RP's number in overtest kicked Amsoil's ass? (3) Do you have any test data of RP's RACING SERIES? Wonder the RACING SERIES would have some comparable numbers with Amsoil's SERIES 2000???? Erick
