Mmm, buttery good.

Nice uoa! I think I'm one of the last subie turbo owner's running a 30 grade. I'm thinking of switching to a 40 grade though. Do you know if this is an OEM air filter (since Si is so low)?

Anyone know the starting vis on this stuff? It held up pretty nicely for the oci!

No make-up oil for 8.2k miles. Nice!

Does the RTS not have a good deal of sodium in it?

BORAT: Very nice! How is the engine performace feel?

I can't imagine a boxer with no consumption over that interval! Excellent UOA!

wOw that's impressive for sure.. what type of oil and air filter does he use?

i'd be curious to see a UOA with a pureone oil filter and air filter with the rotella t

 

[JAG]

Sodium possibly from the butter container the oil was in. That's pretty funny. Assuming that was the case, the UOA is pretty good. This engine is a breeze on oil despite having a turbo. The 2.5L turbo Subaru engines are the oil bruisers.
