Best OIL for the LT1
I didn't think they made conventional oils in Europe! j/k I seriously don't know what kinda conventionals they make in Europe but I would say Elf has some good choices. They're probably synthetic blends at the least.
How many of you have done ANY true research or had used oil analysed? As Buffman said M1 specifically 5w-30 and 10w-30 ARE NOT as good a choice as most of you seem to think they are. If you went to the link Physics posted you could actually LEARN rather than spread ignorance, try it we will all be better off.

I have a contact that is both a Drag Racer and a Engineer for GM in Detroit. He did extensive testing of oil. He recommends Mobil 1 0W30 synthetic.
Is that good enough for you? I'm just trying to help jessebuickguy.

You should PM Patman, he is an oil GENIUS and has owned a couple of LT1s (one which hit 13.6 E/Ts bone stock)
He always recommend the German grade Castrol. He has done a million oil analyses and always finds that one to be the best. Any further info though you'll have to get from him.

The reason Ive always been led to believe is because naturally you will have dino oil build up in places (such as around seals) and basically create a seal itself, but when switching to a synthetic, the synthetic will remove this and because it flows better, will leak...
Ive seen leaks happen because of the switch, not sure if thats the right reason for it however. Keep in mind these are on engines that have miles added up on them already, on a lower mile engine there should be no problem.

You're right, the conventionals gum up and kinda seal things off. But if there hadn't been a leak already, then there wouldn't have been any oil sludge. So point is, a leak is a leak but synthetic tends to leak worse cuz it doesn't sludge.

How long ago was it that your friend did his testing? Formulas change and enthusiasts doing analysis is the only way to keep up on what is doing the job. Patman is a moderator at the site Physics listed so AGAIN I point you there where not only can you get the benifit of his knowledge but you can see the database that helps him come to those conclusions.

The German Castrol (green) changed its formulation, so the good stuff is no longer available. The new German Castrol might be good, but I don't believe anyone has done oil analysis in an LT1 with it yet.
