Royal purple changing interval

[DorBink]

Hi
For everyone using royal purple how often are you changing your oil? I was at a conference and the royal purple rep there said I should be able to get 10000 miles using royal purple. he's never owned a wrx so I'd like to know what guys are really getting.

Currently I'm using valvo and changing around every 3000 miles.

Thanks!

A lot of those long distance between oil change oils seem like a great deal but I dont think they consider turbo model cars to much. I know turbo's like fresh clean oil, not sure Id want 10,000 mile oil feeding my turbo. I go 4K on mobil one. Just over the 3,750 recommended change interval.

Pull samples and do analyses to see how long you can go, unless you are under warranty. If under warranty, follow the book.

Thanks for the replies. I think I'll stick with what I'm doing. I agree with the turbo comment I don't believe the guy was considering turbos etc. Thanks guys
