Hey guys. I recently did an UOA on my Wife's WRX with 18k miles. Got some concerning results.

What are your thoughts?

Interesting, has this car seen long high G turns? Or Does it see WOT while the engine is cold?

Tuned?

Well....when you get rod knock I hope Subaru does not give you any trouble when it comes down to replacing motor. I don't recommend 5w30 or Mobil 1 for these motors.

I had one come back at 3ppm for silver but everything else looked fine. They mentioned bearing wear in mine as well but didn't see 3ppm as too concerning. Anyway, the engine spun a bearing before the next oil change.

Not to scare you, just be prepared incase it does happen.

I'm not biased against Royal Purple at all, I used it in my previous car and I used it in my bike

..That being said, I had excessive oil consumption with Royal Purple, I switchted to T-6 my last fill and that's gone away. Was it the oil or the weight of the oil? Who knows.

bump your interval back to 3000mi with 5w30 RC.

or switch to a more stout 5w30 like M1 5w30 ESP

I realize that everyone hates M1, I am however trying to keep the warranty intact on her car. I was thinking of switching to Pennzoil Ultra. Currently Mobil 1 5w-30 Extended Performance is in the car now. I believe she is at 3000 miles so I am going to drain it and send it in for another UOA

Stop fear mongering. There's nothing wrong with M1 as a brand. Nearly all GF5/RC 5w30s are the same. Your motor isn't saying "damn this tastes like Mobil 1, I don't like it"

The formulation has a lot to do with it. M1 0w40 and M1 5w30 ESP are good oils, even in your Subaru.

What are not good oils, are the 3 different M1 5w30 formulas that are GF5/RC. And those are the regular synthetic, Extended Performance, and High Mileage.

It's NOT "stay away from Mobil 1"
It IS "stay away from GF5/RC"

What oil were you using?

More proof that there's a bearing issue in the 2013-2015 EJ25 motors. There have been many spun bearings in stock and mostly stock 2013-2015 WRXs and STIs. It's very much an issue. Do a search for stock 2013, 2014, and 2015 WRX/STI and spun rod bearings and see how many hits you get compared to 2010-2012 years. It's like 2009 all over again (ie when Subaru had the stop sale on WRXs because of rod bearing issues).

Never said anything was wrong with M1. I run it in my daily driver Civic Si. Just doesn't jive well with EJs in my experience.

I'm a little disappointed to say the least. We bought this car Brand new with 6 miles on it, and so far its been great...but Subaru tech's told us that Mobil 1 is fine to use and if I have rod bearing issues already I'll be a bit angry. I ran it in my Big turbo Cobalt SS and had no issues, even with 10k miles OCI

my 2012 had silver at 5, last oil changed went down to 3, due for another change next weekend. silver initially spiked after a full day road course event, motors healthy though, at least the comp/leakdown say so

Just switch to a thicker oil.

If it spins under warranty just put some 5W-30 in before you take it in.
