Hey everyone let me know what you guys think. This is on amsoil euro 5w30.

Should not be any concerns at the OCI... Which begs the question; Why such a short OCI on such a low mileage engine?
Soon the "what a waste of money" crowd or responses may roll in, of which I do not subscribe to, but again it does beg the above question.
Furthermore, I have to venture into suspicion and say that with a longer OCI on this run the iron MAY have leveled out a bit more.

This was during some tuning changes and getting it dialed in so I was playing it safe. Very safe!
Looks good.
Interesting. Viscosity is a bit low for a Euro 5w30, yet flashpoint is healthy suggesting little or no fuel dilution (I don’t like Blackstone’s approach to Fuel Dilution) . So that leaves shear as a possible suspect for the low viscosity. Are you flogging this car at all? Come on, admit it, LOL. Or was the previous fill a 0w20? (Possible some leftover, not 100% drained).
It’s your car, but I am just curious:
1) how would Amsoil Signature Series 5w30 fare, as opposed to the Euro version? Its HTHS spec is decent, though a bit lower than the Euro’s, but it supposedly is their “most bestest premier” offering. Ask @Pablo though instead of listening to me. [ Edit: assuming you used Amsoil AEL (euro 5w30), oddly the EOT (0w30 Euro) or EFO (0w40 Euro) might do better, even EFM (5w40 euro) or even AZF (0w40 Signature), though again, maybe ask Pablo, as true shear might be your problem, vs fuel ]
2) how would HPL NoVII 5w30 (Euro or USA version) fare?…expensive, I know. As you might expect, the Euro version has the better HTHS spec.
3) how would a cheaper HPL offering do? Especially if you used a 5w40 version…assuming you aren’t short tripping it in the arctic circle. For that matter, an xw40 Amsoil…or even the M1 Euro 0w40. While 9.3cst isn’t alarming, it could be better.
4) how would you feel about using a different lab? Oil Analysers (available through Amsoil) does more complete testing, though their “comments” are ridiculous (poor generic AI-driven comments). Still, if there is something to worry about that a UOA might discover, it would be fuel (or silicon or antifreeze…which admittedly either lab should discover). Oil Analysers does a real fuel test (just REQUIRE them to report it…should be no extra charge, they just get lazy if the reported viscosity is within spec…I would think they would run the fuel test in this case with a 9.3cst). There may be other good labs (but not NAPA or WIX). Look for gas chromatography as the method of measuring the fuel. Again, I suspect fuel dilution is not a huge problem in your case, but it’s what I would be on the lookout for in any Turbo Direct Injected motor…such as your Subaru’s . And low viscosity is the first sign, and Blackstone sux, positively sux, in reporting fuel accurately.

Sounds like we could derail the thread, but is the presumption that OUA is only useful for extending OCI?
Not what I was getting at/believe. As part of doing regular UOAs it's great for developing a trend (you can see mine posted around here) but I find most don't and do a few single UOAs which really show v. little value over a short OCI.
No, TiGeo was pointing out that UOAs are used to assess if the oil is still useful. ANY top tier oil is going to be fine at <3k miles in street use, full stop. If OP or anyone wishes to use top tier oils for 3k OCIs they should never bother wasting money on a UOA. If they’re interested in measuring wear, UOA is the incorrect tool for that and they’re wasting their $35 anyways if that’s the goal.
OP’s owner manual says 6k OCIs. The sensible thing would be run the oil to about 55-5700 miles and pull in-service sample to see if 6k is the max, or just getting started.
Interesting perspective. I don't think a "short" OCI can be blanketly disregarded as useless. All depends on goals and driving habits. Especially when this is his first on this oil+vehicle combination.No, TiGeo was pointing out that UOAs are used to assess if the oil is still useful.

So, can you find even one UOA of a top-tier oil on the board that was not still in spec at 3k miles or less to back up your claim that they’re not useless?
5k is a generally-accepted good point for most “new” combos of oil+car IMO at the minimum, or whatever the OEM OCI is specified.
Isn’t 9.3cst out of 30 grade? I still think something was wrong with test results: very hi flashpoint, yet low viscosity. Lost ~2 cst if not mistaken…and frankly I don’t think Amsoil is prone to do that, though I haven’t focused on their Euro results. Yet high flashpoint “points to” low/non-existent fuel dilution.
I’m no expert, but I take comfort in my (usual) Subaru UOA result above 11cst. Also, keep in mind, EJ25 turbo’s had OM change interval of 3750. I’m not sure what Subaru did to improve things with the F-series, though oils have improved since then. I wasn’t sure what I was looking at at the time, but a mechanic was showing me why he thought whichever F-series motor he was rebuilding “cut a few corners,” so to speak. He was some sort of “go-to” for rebuilding them for insurance/warranty. Not saying that EJ’s were perfect.

In no situation including track use during that interval would 3.5K on a premium product like Amsoil be anywhere close to taxing it. I guess for those that don't believe these products can do that seeing the cST100 and other variables in a UOA can give a piece of mind regardless.
You are presuming that I'm looking for them to become "useless" or that other folks driving behaviors match.
That's quite the absolute.
Yep - for a street driven vehicle. Show me one and I'll change my mind.
3,500 miles of track driving in a street car on 5w30? Show me one and I'll change my mind.
