Its almost time for me to change my oil and I'm wondering what you guys think about royal purple 5w30. I picked up 12 quarts from part source, it was on sale for 10.99/L so I couldn't resist. I read that mobil1 30 weight oils are too thin for M3's. I'm currently using BMW's 5W30 synthetic oil. Is anyone currently using RP 5w30?
