Major draw back I have with Red Line oils is their lack of ACEA ratings (I've learned not to trust API since it switched from being a specification watchdog to a public relations arm of the industry); although I'll give Red Line credit for admitting it, unlike other brands such as RP, who have gotten caught more than once playing games with what ratings they hold...............
