Hello,
Attached is a UOA from Oil Analyzers for my 2022 WRX. I dropped the factory fill right at 1000 miles around May of 2023 and ran HPL PCMO as per recommendation from HPL themselves. It rolled over 5000 miles just before Thanksgiving and right around when I usually start driving my ridgeline more due to winter weather, skiing, wood hauling, ect. A little background, the car has been tuned using a Cobb Accessport since about 1500 miles, first it was an OTS tune, or a general tune for a car with no aftermarket parts, I believe this tune for 93 octane yields about 300-310 hp and 320-330 tq. I then made it a cobb stage 2 and bought their intake, which is just a higher flow air filter and new piping post MAF, larger intercooler, aluminum charge pipe, and Cobb exhaust. I had it Etuned from one of the biggest, most reputable Subaru tuners in the nation. The Wrx now makes around 330-340 HP and 350-360 tq.
I drive my car daily until there was threat of snow (will drive it in the winter once I get the front end PPF'ed) trip is about 18-20 mins mostly rural two lanes and a 5 minute highway run at 60mph. Oil temps as per the cars own readout are usually around 198-201 on a normal day once I reach the office. I normally don't drive too aggressively at least until oil temps reach 180f or so.
I'm not sure what to do about the high fuel in the oil, this is my first DI and Turbo car, so some learning curve involved. I'm not worried about the silicone in the sample as it has been shown that Subaru used way too much sealer when constructing the car. I don't drive on dusty roads which would lead me to believe the air filter cobb sold me was too high flow and not enough material to filter smaller particles. I think if the SI doesn't trend down in the next two samples or so I may think about switching back to the stock air filter and contacting Cobb regarding my findings.
I did refill the car with the same HPL PCMO 5W-30 but will not be driving the car again until April or so, so another sample will probably happen later summer or so.
