Slight difference in language, but at least for me the takeaway is the same. I'll use a 30 weight oil at the track and the thickest cheap 0w20 or 5w20 for everywhere else. In normal conditions, the majority of engine wear happens on cold starts so I think for non-track driving it's important to have good cold start protection.

Yeah, i have been using PUP (pennzoil ultra platinum) 5-30 on the gen1 and will likely continue to do so with the FA24. Project farm did an engine oil shoot out a while back and it barely came 2nd behind amsoil. The UAO which came back after 2 track days were spectacular. Thread is here if you are interested:

I just don't want to void the warranty if 5-30 is not spec'd for the engine.
