I think there is a big misconception in regards to synthetic and conventional oil along with weight.

I haven't look at a VOA on it recently but at one time M1 10w-30 was VERY nearly a 10w-20 it was much thinner than their 0w-30 or 5w-30.
The Lucas crap is just thick oil without meaningful additives so all you have accomplished is thickening the thin oil and diluting it's additive package.
Posts like this are proof that the guys saying, "just about anything will work" are right.
Oil preferences are marketing based the VAST majority of the time, what one works "better" is splitting hairs and UOA is about the best tool we have to do that, a FEW folks in this thread have mentioned it but not many.

10w30 is a No No in my opinion for ANY Ls that is ran hard especially in the summer. I ran 10w-30 once in the summer in my cammed ls6 and spun a rod bearing at the track. When I checked the oil (keep in mind it was 90+ degrees) it was like WATER, and VERY THIN. I will NEVER run a light oil in the summer again. Now I run 10w-40 Rotella T6. And it has zinc in it which helps attract oil to metal. High RPMS and thin oils equal DISASTER!!!

I run Joe Gibbs LS30. Below is a very good read regarding some testing done on Joe Gibbs LS30.

Please answer EACH one of these.
How does a single pressure test simulate the actual conditions inside an engine?
How does it simulate the oil heating and cooling as it contacts various parts as this relates to breakdown.
How does it simulate how the oil copes with contamination?
Exactly where in the engine are 4 ball bearing pressed together with 50tons of force?
How does this simulate more than 5 minutes worth of runtime?

best oil for the LS1 engine? i.e. sludge in oil = no sludge in engine

It all depends on the quality of the oil you used. Blindly jumping to a 10W-40 doesn't necessarily give you any more protection than a quality 10W-30 oil.

I can't really provide any answers to your questions. If what I posted was not relevant to this thread and what's being discussed, then I apologize.
