Got another UOA on my 2011 WRX, at about 26k miles. Boring UOA, pretty much the same as last time. The TBN was a little lower but nothing to worry about, once again shows that in my driving situation at least, this oil is safe for 5000 +/- mile UOAs. I still don't think I'd want to do the manufacturer required 7500 miles, though.
Probably won't bother getting another one again for a while at this rate, unless I forget that it's unnecessary.
Just like last time, these results seem to show that there's nothing wrong with a decent sun 5w-30 in these engines for street use to keep the warranty intact, and that the Subaru branded 5w-30 is a decent syn. Agree/disagree?
