The biggest drag these parts encounter is fluid drag which is a direct effect of viscosity. Whenever I encounter oil that boast of more hp, I always take a look at the actual viscosity, usually they're made at the thin end of the grade.

In addition, although I'm one of the very last BITOG-ers who'll you'll hear argue against synthetic oils because of price, I would say in this case that for ~$17 per quart, it really better be doing something very, very special. Of course, you'd also have to compare the relative prices of other oils in your market. I'm thinking that a lot of our 3k OCI diehards might change their thinking if our lube oil prices headed in this direction! Bottom line for me is that I use green German Castrol 0w-30 (of which I have a large stock) that cost me on average slightly over $4 per quart. For my ~10k OCIs, there's no oil that could provide more than triple the benefit I get from the GC.
