Fantastic oil, and the best I have used to date (including M1, PP, Syntec, RP, Amsoil, etc...).
Application is an older inline-6 BMW that was mainly a weekend canyon carver & occasionally saw the track. Not as good of a long-drain oil as Amsoil, but definitely made the engine. 10k miles should be no problem for Redline.
Will be going back to German Castrol or M1 5w40 TDT in the BMW until the DINAN turbo is installed later this year, at which point I'll be going back to Redline.
