Yes, that is a very good observation, thanks.

I think I'd get the consumption issue checked! 2000 RS with 150k miles here and never more than a .5 quart between changes using Pennzoil HM 5/10W-30 or MaxLife 10W-30.

No track time per se, but sees daily use on the NJ Garden State Parkway (same thing ).

1st UOA. '14 WRX Factory Fill.

Replaced it with RT6 5W-40 and am anxious to get the subsequent UOA to see how the metals do. Any input is appreciated.

It's really hard to draw any conclusions from the first fill. The metals look unremarkable from a break-in perspective (that's good!) and the viscosity is low, but not unexpectedly so. The TBN is pretty low given the low mileage, but obviously fine. Silicon is pretty high even for a factory fill, it's most likely RTV compounds washing out, but watch it in the next fill, your OEM air filter may have a small problem.

I thought that comment about the silver was very interesting.

That was something I brought up to them a few years ago that at the time they didn't seem to know about.
To my knowledge it hasn't been a problem in the newer ones though.

Stock 2013 STI
5w30 Pennzoil Ultra

Lots of Autocross and 3x as much track time as previous sample.
Oil sees 220F to 230F autocrossing. 260F sustained when hot on track.
0.5 qt replacement, most of it being when the oil filter was replaced to install a oil sandwich plate to measure oil temp there. Just went ahead and replaced the filter.

Pennzoil Ultra is a really good oil, but I've moved on to RLI 5w30 HD LA. Oil pressure was as low as I'm comfortable with at 260F.

Enjoy.

i see your silver is up due to your racing as was mine. my oil had almost 150 miles of on track time, does the high silver bother you? you also have increased sodium as well.. it was the similar to mine.. blackstone told me to use "caution" lol my report is post 351

i guess my question is does any of it bother you? i decided im looking way too much into these oil reports, i will keep doing them, i am actually going to change my oil this weekend about (1000 miles)with some mobil 5w40 or 0-40 havent decided yet

That the same place I am thinking of..?
The main bearings?

I haven't kept up enough on all the UOA's, didn't know of other years showing silver in the oil.

Default Post your used oil analysis (UOA's) here!

Copper doesn't look so hot either. Hey look, the oil sheared but still stayed in grade (just barely).

What lab is this? I notice they actually did a fuel reading instead of estimating it based on the flashpoint like Blackstone does (BS usually reads slightly lower than actual for this reason).

Sticking with a 5W-30, eh? RLI is supposed to have a high HTHS, IIRC (just saw that it's 3.6). Don't be shocked if the first 2 or 3 uoa's on it have higher ppm wear numbers though because it will be cleaning your engine. Let us know if you also use it to make popcorn.

Edit: The RLI 5W-30 LA = Low Ash. Any idea what the additive pack is like on this oil? ZDDP levels the same as GF5 oils? Does it use copper? Does it use antimony?

Yep, main bearings. It seems Subaru switched from lead to a silver alloy (silver/aluminum?) some time between 2007 and 2011. My car has always shown 2-3 ppm of lead, but no silver. Later cars sometimes show silver. Not sure how much a thicker oil will help, I've seen lead in my car with RT6, and it seems to be related to track-day and autocross activity.

The copper is a really good question. Two possible sources, the oil cooler and the turbo bearings. The former is innocuous, the latter disastrous. I haven't looked carefully but I don't think the small end bearings are bronze. Anybody know for sure?

I second the lab question.

Don't have much time to post but a few answers.

RLI 5w30 HD uses antimony, no copper.

The lab is http://www.testoil.com/ which I sent through Terry Dyson.

Ah, TD. I know he generally doesn't recommend going thicker than a 30 grade on stock Subaru turbos, but I'm surprised you used PU 5W-30 at the track.

Hopefully the RLI will do well for you with the high HTHS, bio-based ester base stocks, and good additive package. There's a uoa or two in this forum on RLI 10W-30 from a Baja turbo in some pretty severe driving conditions.

Tin looks like it's making little jumps as well. Borrowing a quote from bitog in a recent reply to a WRX uoa on PU 5W-30.

"Before leaving BITOG, a wise wise man, a long long time ago told me that when tin is elevated to abnormal level as it is in this report it usually means that the viscosity is too low. Like others have said move to 5w40. Indeed Rotella T6 has a cult following on the subie forums. For an oil that costs around $20 for a 5 quart jug at wally world it sure performs great!"

d0000000d! No just no. Save yer money! No need to run some fancy OIL!

There ya go US. I saved you the trouble.

And to think, a Subaru super expert proclaimed to me that there is no silver associated with the main bearings... (discussions about the early '09 wrx main bearing problems)

Well, it's possible that I'm wrong and that Subaru made two changes at approximately the same time. It's possible they replaced the lead main bearings with Aluminum (no silver) and also replaced bronze small-end bearings or something else with silver at the same time.

So, I should have been clearer. We've got pretty good evidence the latest engines don't have lead main and big end bearings, as none of the recent cars show lead in UOA. The lead seems to have been replaced by silver in UOA, so the logical conclusion is silver main/big end bearings, but we don't have irrefutable proof of that i.e. teardown results.

The discussions on '09 wrx spun main bearings are pretty lengthy. I can't say of any irrefutable proof either, but when my car, which a VIN dead center in the 'bad' range, had shown high silver for all UOA's I did to it. I eventually changed out the short block to avoid a likely big failure down the road after the warranty ran out.

Curious what the first UOA will show on the new block. Which should be relatively soon (under 1000miles to next oil change).

My latest, at 8000 miles. 4.5 quarts QSUD 5w-30, 1 quart topoff RT6 5w-40.
This sample had less highway driving than the previous.
Looks to me like the viscosity is failing pretty quickly, time for a bit more topoff of RT6.

Nice shot of moly in that QSUD. I wonder if the QSUD 5W-40 has it and if it's as easy to find as the 5W-30? I think that's what my local Ferrari deal uses because they don't carry Ultra 5W-40.

Under 9 cSt with a quart of RT6? Yikes. That stuff is not very shear stable at all. Looks like it might be a good choice for my Civic which takes 5w20.

It's good to see a 2015 WRX show low fuel dilution, though I'm always dubious of Blackstone's fuel measurements. What's your driving like? Mostly longer trips? Winter will be the real test for the new DI cars.

That silicon looks a bit high even considering washing out the RTV. At 8,000 miles it should be mostly gone. You might check your air filter just to make sure it's seated properly.

owowowo maaaan....that just aint right!!!!

i finally added about 1/2qt the the other day....im at 8100 miles on this rt6+racing 4t oci and im driving it another 1000 miles and then gonna change it....


meh...not worried in the slightest.....

Default UOA on Motul X - Clean 5w-30 - 5k miles

Here's my second UOA on Motul X Clean 5w-30. 5,022 miles. Looking good from what I can see. Haven't had to add any oil between changes yet. I have Amsoil Signature Series 5w-30 in their now. Think I'm going to stick with the Motul though.

Why? Boost it with some Amsoil EFM or DEO 5W-40. Also running the Amsoil to 5k miles?

The Amsoil came as a suggestion from Mike at AZP to run longer intervals. I trust those guys so I gave it a go. I'll be running it to 5k again and will base my final decision on the results from that UOA. For the price though I think the Motul is already a winner since I can get the oil and filter from AZP at a very reasonable price.

Always happy to hear your input though!

I know Mike and purchased my Motul X-cess 5W-40 from him. I've run Amsoil SSO 0W-30 before and it wasn't robust enough for my application and my extended drain intervals (at the time). The additional calcium is helpful for extended intervals, but the HTHS and viscosity are typical of 5W-30's.

I wouldn't use a couple of random uoa's to compare oils though. I'd choose based on HTHS and viscosity at 100C.
