The one that's been talked about on this forum the most is the 300V "Power Racing" formulation that comes in the metal 2L cans, if that's what you're looking for. I can't say I'd necessarily recommend it as a general purpose solution for our cars though. It's a great oil, but it's pricey and tends to be on the hygroscopic side (absorbs water faster), which will turn it acidic faster. If you're tracking the car, staying way on top of short-ish oil change intervals, and willing to shell out for it, it's good stuff. It's what I use (although I recently switched to the 5w40 version for summer). But if it's going to sit in your DD car for over 3 months sucking up humidity, especially if you're not parking in an enclosed garage (more humidity and temp-cycle exposure overnight), that's not so great. For normal-to-extended interval regular DD oil, I'd probably choose some other quality synthetic that's easy to source locally and more resilient, e.g. Mobil-1 Extended Performance.
