    2021 WRX STi - Switched from OEM oil to Motul X-clean EFE 5w30 - 19,685 miles

    This Motul was run for 3 OCIs. Copper was down on the latest one. What about the silver, though?

    It seems that the Xclean EFE is a mid SAPS oils so a full SAPS would have even more sulfur, right? Maybe going with a low SAPS 5w40 would cause less copper reactions.

    Do you know what the difference between the Euro and Euro L are? They both come in 5w30 and have an HTHS of 3.5. The Euro L also has an SN certification while the Euro doesn't even though Pennzoil says it meets the engine requirements.

    I bought it new in October of 2021 so I still have about 3 months on the bumper to bumper and a little over 2 years on the powertrain warranty. Yes, I’ve seen that part of the manual. It also says 5w40 can be used for replenishment but should be changed back to 5w30 at the next oil change...

    Are there any API SN+ 5w30 oils with a decent HTHS?

    This is my second car ever (drove a Honda for 15 years) so I’m not used to the oil consumption. I know it’s normal but it still gives me anxiety. But believe me, a part if me wants to go back. The numbers were all good except for viscosity. Everyone always says the OEM oil is terrible too. Maybe...

    Here is my most recent UOA with Motul 5w30. Copper is down but silver is up. I’m currently on Amsoil SS 5w30 and will have that tested soon.

    Yeah, viscosity is way better with the Motul. There’s a lot less oil consumption too.

    Interesting. Does the Motul have a lot of sulfur? It’s my daily. My commute to work is 10-15 minutes. I warm it up for about a minute in the morning before I start driving but I wait for it to fully warm up before getting on it. I don’t beat on it but I might drive spiritedly here and there.

    Yeah, but the language is vague and says 5w40 can be used for replenishment only. I’d rather just use a robust 5w30. That’s interesting about the oil cooler part number. Since this seems to be common with newer Subarus, I wonder if they used a different one for older ones? And if they did...

    Yeah, I saw that thread. It seems similar to my situation. I wonder if the oil coolers in both engines are the same or similar?

    Which numbers do you mean, specifically? What numbers do you mean, specifically? Other than the copper, I don’t see any that stick out. Yeah, the car does seem much happier on the Motul. It’s quieter, smoother sounding, and much less oil is consumed.

    2021 WRX STi - Switched from OEM oil to Motul X-clean EFE 5w30 - 19,685 miles

    I’d like to stick with a 5w30 for warranty purposes.

    Yeah, I’ve read similar things from different owners on different forums. It’s a benign issue, right? I’ll deal with it if it means less consumption. I’ll keep reporting back to see if the copper goes down.
