And there's a very good possibility I don't want NASCAR oil in my G37 or F-150, either. We understand the point. You know full well I have no problem with non-approved lubricants, within reason, including the original thoughts related to this thread. That doesn't open up all kinds of doors or change the rules of logic, however.
Red Line is a great oil. I don't doubt that at all. It is an expensive oil, mind you. Joe Gibbs certainly makes a lot of good oils. They're more expensive yet. I might be able to justify to myself running Red Line in something like my G37, though that's pushing it. In any case, there is a limit to what I'm willing to spend, since there are diminishing returns. Don't forget that oil used in racing, too, may or may not be the same as or even similar to something you can normally get off the shelf. Endurance racing tends to use something fairly roadworthy. Funny cars and Formula 1 certainly do not.
As for diminishing returns, Joe Gibbs provides a perfect example. They and others trumpet their utility to even a stock small block Chevy. Yet, for the price of two or three Joe Gibbs oil changes, I can replace a cam and set of lifters. That's what I'm talking about when I mention diminishing returns. Spending $300 on annual oil changes to protect $200 worth of parts is foolhardy.

That's right, and the Force India F1 team uses Quaker State, so I must be really set.
