I think somewhere I read that HPL goes ahead and uses both types of Moly. HPL guys load them up lol. But given the price of Valvoline, I highly doubt they use both types. They use what quacker state uses, and the amounts are pretty similar
"beat"
Had better wear numbers, did better slightly. Splitting hairs to be honest. Might have been a one off.
Yeah I think we've beaten that topic to death in other threads (why 3 pulls on a dyno and looking at a $30 UOA doesn't show one oil "beats" another one).
That also means that there is no easy way we can test the expensive oil's big claims. I'm sticking to the cheap one
I wonder why your engine became an oil burner. Bad design or not serviced on time?
That's sad at 5K oci. Are Subarus known for this kind of thing?
I do believe it was a combination of mediocre base stocks, low tension oil ring design and severe service.
Subaru things.
My sister has a 2022 Outback with the 2.5 Turbo. I sent her three 5 qt jugs of Pennzoil Ultra from Amazon. I keep telling her to change her oil every 3,000 miles no matter what. She doesn't know a thing about cars, next year I will send her more oil as a reminder
Good news is I maintain 4 Subaru’s total with a long term ESP 0W-30 test going on as we speak.
She has a warranty and an extended warranty so we need to be careful with the viscosity. But I think as long as she changes her oil three times a year, she should be fine.
I do a 6 mo, 3K OCI using premium D1G3 synthetic oils of the recommended grade on GDI vehicles in my immediate family. I’m of the unsupported opinion that this practice should virtually eliminate any oil-related issues.
Three jugs of ultra cost me like 72 bucks, and she will probably pay like $100 for labor to change the oil. That's less than $200 a year, absolutely worth it to protect your expensive SUV. I don't care how much life is left in that oil, just drain the thing out.
