I find it interesting that he now agrees that Mobil 1 EP is mostly Group III and not ideal for high performance.
December 2006 ? Seems debates over base stocks that far back will not match what is in the stores now …Mobil1 has updated their website. Reg M1 now good for up to 10K miles (in print) / 30% PAO (5W-20).

There are no new base stocks in general use since 2006.
