Mazdaspeed6 2.3L DI Turbo Oil Recommendation

[shpankey]

I've been ecstatic with the Red Line 5w30. Turbo spools noticeably quicker, which is fun. It's not an oil that is covered under warranty requirements though, but I just couldn't go back after using it. I tried but the loss in turbo spool was too disheartening. I'm thinking of switching to Red Line 0w30 for non midsummer months though. But I do like the thicker 5w30 for peace of mind as this car is a fuel diluting shear monster turbo that beats on oil. Every oil I've ran other than RL was quickly turned into a 20 weight.

Mine's an 09 MS3 GT btw, different car, same motor. Love it!

Why don't you think the 0w30 can withstand that?
