I would go with at least 3k since the more robust factory fill additives likely help with break-in. People change early in an effort to “get the metals out”, but if you compare uoa’s, more frequent oil changes don’t really speed up the process.

Any metals small enough to pass filter will be ground down by the engine. Bikes have clutch in the engine oil and I have never heard of clutch material not captured by the filter. |

Here is my 15 WRX history of reports. I used few oils and did analysis for each distinct one:
stock engine: 24k: Motul 8100 X-cess 34k: Mobil1 5w30, non-esp stage 1 (cobb) 41k: Amsoil 5w40 53k: Amsoil 5w30 now running M1 ESP Last edited by CrimeaRiver; 01-05-2019 at 01:14 AM. |

Here is my first UOA with my 2017 WRX. Subaru Synthetic 5w30 with 3,871 miles.
I replaced the oil with Motul 8100 X-clean 5w30 EFE and hope it will test as a higher viscosity than the Subaru oil. Other than low viscosity, why does Subaru synthetic get so much hate? I have a short (3 miles one way) commute to work and my oil temp doesn't reach full operating temp most trips and all my wear numbers look great to me. And after looking at many other UOA from the "better" oils, high copper levels seems to be a trend. Does Subaru synthetic really deserve the hate? I am also new to UOAs so please excuse my ignorance. |

No, not at all. People will do one uoa on the Subaru oil and it will have a used viscosity of a 20 grade and they proclaim it is the worst oil on the planet. Or they will have a failure after modifying their car to Stage 2 and state the same. This is a great article about uoa’s: https://www.bobistheoilguy.com/used-oil-analysis/ |

Thank you for the link. After reading the article I’m strongly considering going back to using the Subaru synthetic oil depending on the results I get from the Motul X-clean. The Subaru synthetic appears to work well in my car but I might shorten the OCI in an attempt to maintain a higher viscosity.

2015 WRX Used Oil Analysis Thread
Quote:
X-clean will have a higher viscosity since it starts higher and ACEA C3 oils have a higher High Temp High Shear (check out HTHS in the Oil Selection Guide sticky). Some GF5 oils shear to a 20 grade in 2,000 miles or less (or from fuel dilution). Generally the DIT’s show good uoa results even on oils with an operational viscosity of a 20 grade on 100% stock cars. Start modding, get a bro-tune, track the car, etc, and it’s a different story. Even with good uoa’s there’s no guarantee that you won’t have a failure. It will be interesting to see how Ascents are holding up after a couple of years running 0W20. |

not a subie but on the same lines. girlfriends 13 malibu LS 2.5L DI naturally aspirated was dring spec 5-20 semi syn when new, a qt on a thou. then synthetic 10-30 was put in + cut consumption to qt on 3 thou, now as it gets worse a 5-40 euro spec in it + no adding in 2500 miles. engines like humans are all different so use what works for you + your climate.

Mobile 1 ESP 5W-30 Used Oil Analysis and TBN
Got my first used analysis and TBN done on my 2018 WRX (6speed, premium).
Break-in period I kept RPM below 4,000 and varied between 5th and 6th gear on freeway travel every so often. My engine burns zero oil. @1,000 miles: Oil change with Mobile 1 ESP 5W-30 and OEM filter. @6,000 miles: Oil change with Mobile 1 ESP 5W-30 and OEM filter. @9,000 miles: Installed PERRIN AOS (OB-2 says nominal air/fuel ratio, vacuum pressures, maximum boost, etc. Installation affected no factory performance parameters.) @10,000 miles: Oil change with Mobile 1 ESP 5W-30 and OEM filter. |

2015 WRX Used Oil Analysis Thread
Silicon and copper still showing the typical elevated break-in levels. Probably not much difference in wear metals if you would have done only one or two oil changes at this mileage. As long as it helps you sleep better at night.

Damn, not that good with this UOA. M1 EP 5w30. I even thought i changed the oil too early. Was going to change this oil out during summer lol
Worked well in my C7Z, not so much in the wrx. Good thing because i just put castrol magnatec 5w30. See how that is for a couple of months. THen doing another oil change end of summer. |

Pretty typical DIT UOA IMO. Still showing some break-in wear and typical DIT fuel dilution. Nothing wrong with the oil. |

In my 2016 wrx i never had dillution issues or anything above single digit ppm copper or iron for 5k intervals with a lot of cold start idling and beating the piss out of it. (I always ran german spec oils though). For 2k miles that looks terrible. If its all short trips its understandable, but if the oil gets up to temp often, something is wrong.

I used the same oil in my C7Z, that UOA with 3k+ miles looks a lot better. The UOA i posted for the wrx, that was my 3rd oil run since ownership, from 5,743 miles to 7,795 miles exact. Magnatec is in the engine now. Will drain it at 10k or just shy of it and get another UOA. The car is a lease so honestly i don't care for the long term. I just don't want issues now while it's in my possession. Car is also a daily driver. So it gets used everyday. LOts of stop and go, lots of idling, lots of short trips (that's probably the culprit), lots of quick start/shut off since my driveway has tandem parking so if a car in front of me has to leave, i move the car to let them leave, park it back and shut it off. That doesn't happen a lot but it does happen, i'm sure with everybody. Honestly after about 18-19 months with the car, i'm not happy with it. Can't wait until the lease is over lol |

Yep, that’ll do it. Guessing the actual fuel dilution is 4-5%.

It's a daily, i obviously take it out lol It's just not a car i thought it would be. It's still a fun car. But the gearing sucks, and it's slow. Rattles and vibrates galore, and because the gearing sucks, makes driving stick everyday terrible. It's a good car, i'm just not happy with it. Which is why i can't wait for this lease to be over. |
