UOA for the oil is in the UOA section."..Says loads of racers use this same oil combination with great results.."
To give credit when due, they did not specify which results they were after, maybe less bloat and farting at night was their great result.
Great, so you know what this really should have been? A quick post in the "latest oil change" thread with a photo of the car.fwiw - I'm not asking for advice on what to run
Fwiw - I haven’t posed a question. I’m not doing a search.You're going in circles down a spiral rabbit hole.
I don’t - the 5w30 army is just alarming. I get the anti-Lucas army.Why do you even care what the rest of us think about this?
I was waiting for this to happen...

I did, when you first posted it. You said, "I'm thinking I'll just go with Mobil 1 15w50 and no additive". That's not a rock-solidly confident sounding statement, so of course on a discussion forum you're going to open up a discussion.maybe check out the original post
People saying to run the prescribed weight on the fill-cap in a stock engine being used in reasonable conditions is "alarming"?I don’t - the 5w30 army is just alarming. I get the anti-Lucas army.
When we know with 100% certainty that the 30 weight was only prescribed to meet a CAFE target - yes.People saying to run the prescribed weight on the fill-cap in a stock engine being used in reasonable conditions is "alarming"?

I really wish you had not said that, it is kind of a Bitog Secret.Tigeo recommends liqui moly for everything
Prescribed to both meet a CAFE and ensure adequate protection. You're looking at this whole thing far too black and white. The reality is that the vast majority of car owners, Corvette or otherwise, have run their vehicles solely on the weight marked on the fill cap. There was never a series of publicized LT1 lubrication related failures. Common sense tells us, the 30 weight proved to be fine. Since you're so allegedly data-driven, show us how 30 weight oils have sabotaged the longevity of LT1s. You can't.When we know with 100% certainty that the 30 weight was only prescribed to meet a CAFE target - yes.
That part here in this whole thing that is so crazy is a 30 grade oil today could be considered thick and many performance vehicles run 30 grade on track. Here, I realize this is an older vehicle but that V8 shouldn't need anything more but I get him wanting to run a 40 or 50 which of course is just fine. But this isn't CAFE thing 8/16/20 here.....that V8 will happily run a modern synthetic 30.Prescribed to both meet a CAFE and ensure adequate protection.

Well, you seem to be struggling to find the "best" oil viscosity to use ... so it is somewhat of a "search" for input from the BITOG community.Fwiw - I haven’t posed a question. I’m not doing a search.
There have been caveats put on the 5W-30 use in this Vette ... that is, if it was just spiritedly driven on the street and only use in Auto-X, then a stout 5W-30 would work fine. Auto-X is not going to get the oil very hot, especially when the oil is probably not even at full operating temperature when you start the 60 sec (or less) run through the Auto-X course. If you are going to do 20-30 min track sessions, then for sure go with a good xW-40 or xW-50 if the 50 makes you feel better. If you ever plan on doing a track day, then just run the 40 or 50 from the get-go so you don't have to bother changing oil for a track session.I don’t - the 5w30 army is just alarming. I get the anti-Lucas army.
[I will say that if anyone had compelling application specific data that proved Corvette, Lingenfelter, Callaway and Mobil wrong I would absolutely consider it.]
