First UOA on my 2002 WRX wagon acquired in April. Wanted an idea on the health of my engine.
No major modifications (just turbo-back 3" stainless Vishnu exhaust). K&N KN-1015 oil filter. Wix paper air filter. Comments welcome, thanks all!

COMMENTS:
AARON: Your WRX is average. Now, in most cases in life, that's not necessarily a complimentary statement, but from an oil analysis standpoint, average is a great thing! The far right column on this page shows average wear for a Subaru EJ205 turbo engine after ~4,500 miles of oil use. You ran just as long as our average oil change, and metals are right in line with averages, just as they should be. That tells us that this is a well-maintained engine with no problems developing at 211,535 miles. The TBN is good at 3.5, so leave this oil in place another 2,000 miles. Nice report!
