I know these are both good choices in a turbo Subaru, but I just thought I would share these entertaining (?) comments posted at nasioc. This thread was split off from the original thread because it went a little crazy.

Not a fan of Rotella because it doesn't hold up well under high load. Use Motul 5w40 or Mobil 1 0w40 (only this weight) with your next motor for better lubrication/protection.

Just search this forum and look up engine failure and see how many people were running Rotella. Also, if you have a oil pressure gauge and you run Rotella. See how much pressure has dropped after a hard run at both idle and cruising rpm's.
Use it at your own risk. You have been warned.

Actually, you clearly don't know the difference. Both Rotella and M1 0w30 suck because they both have huge pressure drop (thins out) when pushed. However, M1 0w40 is a completely different oil and is considerably better than both of them, but you wouldn't know that would you? Because you talk out of your [censored] and assumed M1 0w40 is just like 0w30. You're a typical internet idiot, that doesn't know shiet, but talk alot of [censored].
The bottom line is, Rotella kills bearings and should never be used in turbocharged Subaru engines. Only an idiot and a fool would claim otherwise.

The "actual" amount of pressure drop/thinning of Rotella and M1 0w40 is very different from each other in real world conditions. All you need to do is monitor the oil pressure of both oils under hard conditions. Rotella drops considerably more (i had seen it drop by 10+psi) than M1 0w40 (around 5psi). Hence Rotella has a poorer ability in continuing to provide a layer of film between the journals and the bearing under high load situations. Also, it's clear that you and many others have not used M1 0w40, let alone monitor how it behaves over time. I have and the difference is day and night compared to Rotella. Rotella breaks down quickly and is about as good as water. With that being said, I like Motul 5w40 the best. It holds up better than the other oils under high load, however it not readily available everywhere like M1 0w40.
As i said before, use Rotella at your own risk and don't buy into the fanboi [censored] that's a good oil. You have been warned.

What are the chances that someone here has some OP readings on both?
Discuss.
