The 0W-40 interests me also. I would not go as thick as a 20-50 (or even a 15-50), I don't believe the clearances are large enough, nor does the engine oil run hot enough to need 50W.

The 0W-40 might provide a bit more bearing protection than the 30W without the downsides of a 50W oil.

This report looks very good. I also have a twin turbo Supra and have been considering switching from Redline to M1.

I would. As good as they say Redline is, I havn't been that impressed with it. I think with Redline you start to get into what I call "overkill". I think Redline has it's place though.

I think there is a fair amount of Fe and Pb wear in this sample after only 2500 miles. I think it's worth considering a heavier 30wt oil like Redline 10w-30 or perhaps the Mobil 1, 0w-40 in order to increase bearing viscosity and oil pressure under these severe conditions.
