Thanks for posting your reports. I visit BITOG often but when I read the UOA reports, I rely solely on the commentary of members as I don't yet know enough about oil to understand the reports themselves. Is the 2ZR-FE notorious for shearing oil?

I'd love to see how SuperTech Full Synthetic holds up but I think they only go up to a 5W30.

Have you tried Rotella T6?

A quick search at BITOG yeilded this: It's largely about motorcycles but maybe helpful, maybe not.

The 2zr-fe is a relatively clean engine just like the 1nz-fe. I havent tried any other oils yet, but the next one will be Motul.

Your link to the oil forum was an interesting read, and it makes me think Mobil1 and Amsoil might be using the same base stock oil. I was using 10W40 oil in an engine designed for 5W30, so I dont think the viscosity was the problem. Or maybe I do need to go to a 15W50? Who knows...

I've read that Motul oils are quite robust. Best of luck with your testing. The thread will be interesting.
