Only use motul. XCess gen 2 5w40 for the ‘04 wrx. I get oil samples sent to the lab on the wrx and it has consistently been improving results since switching to motul. At first they were worried about the motor and now they say it looks clean as a whistle

Pros: improving oil analysis results, engine looks clean

Vehicle: Subaru

I switched to Rotella T6 (5w-40 Full Synth) after running Penzoil, Chevron, Castrol, Mobil, regular non-high mileage 10w-30 dinos in that order over 4000 miles. Worst of this bunch was Mobil and Chevron, the HLA tick was unbearable, even right after the oil change.

Pros: engine cleaned up

Cons: HLA tick unbearable

Mileage: 4000 km
