First analysis for me, but from what I can tell the numbers look pretty good. Ran the fill longer than I wanted to/usually do, but doesnt look like it hurt anything. No makeup oil, Subaru OEM blue filter.

Looks beautiful

Is this an FB or a EJ?

Looks OK, though many typical constituents seem underrepresented.

KNOW this: you will never see impending sliding/rubbing/ component failure macro wear in this UOA.


I recall there being no moly carbamates in NAPA SYN. Did you use an oil that has the Infinuim premium package as a component previously?

Or, possibly, der !VERBOTEN! LiquiMoly?

Looks good OP. Don't change a thing.

Engine is the 2.5L EJ, Naturally Aspirated.

I honestly dont know too much about the previous oils that were in the car, since its relatively new to me (only a year old). I do know it had some PYB in it prior to the NAPA Syn, but that was for a 5k mile stint, and thats all I know. The changes before that are a mystery.

Current fill is Pennzoil Ultra Platinum 5W-30, Subaru OEM filter. Will post a UOA afterwards to compare between the two.

The Moly may very well be from the Napa Syn. There are other brands that constitute different additive packages for different viscosity. Castrol GTX comes to mind.

This UOA looks real similar to my recent results on my wife's Forester.

Also want to clarify it was 5w-30, not 5w-20. Can't seem to edit it now.....

In that case, what ARCO said stands...

Napa Syn 5w30 has not Moly (per this 2013 VOA).

Nice report and thank you Wemay for the info on Castrol VOA's

Probably carryover from the high moly PYB; Moly does indeed carryover.
