Yep it sure is!
I know, I know, there is a search button, been there done that.
I'll just start by saying I am a bit mystified as of why Subaru has suddenly changed oil types for their 2.4L Turbo engines for the Outbacks and Ascents. So, why the oil weight change for the 2.4L FA24DIT vs the FA20DIT in the older Forester XT? It's literally the same engine platform with a bore/stroke change. So is this just something to meet CAFE regs? At 750 miles I dumped the factory 0w20 oil and filled it with Red Line 5w30 and I have noticed the engine is noticeably quieter and seems overall smoother from it's cold starts, to running at highway speeds, to idling at stoplights. No noticeable loss of MPG or power. It seems like a lot of folks on the Subaru forms are all over the place with what their reasoning's are for this and what oil should really be ran in this engine. To me it just seems that these boxer engines are very "clattery" with 20wt oils.
So, stick with factory recommended oil or break the rules and run what should be ran in it?
