Which Oil

It just gives better protection on cold start up it is not going to hurt your engine in a warm climate. Do you need to run a 0W? No but it won't hurt either. The one thing you say that I do agree with is that if you insist on running M1 the 10w-40 is far superior to the 5W-30 for an LSx engine. I pretty much disagree with everything else you said but I don't have any energy left to argue.
and arguing?

Do a simple search and you'll see.

Now see what the CST is on a 50 weight oil? The LS1 likes a CST of between 12-13. 16-21 is WAY too high. Don't believe me? OK I can spout about 100 threads from here where our resident oil expert (Patman) has given the ideal CST for the LS1. Patman is one of the founders of the bobistheoilguy site and is known as being an oil expert. Here are a few threads for you viewing pleasure. Hopefully Patman will see this thread an chime in.

That enough or do you doubt the oil expert here too?
Enjoy...
That's all I was asking for, your previous posts were no more than opinions without facts
now we have what we should have had before thanks for taking the time to post the references for all to read.

Here are a few more threads with oil test results. Just in case you doubt Patman's word that are backed up by actual oil tests....

If you read as much as I did here you would feel confident in saying what I have said about oil. I do not and never have claimed to be an oil expert I just trust Patman and his advice as helped my car stop sounding like a sewing machine and stopped my burning oil problem.
I didn't think my first response to your post was bad I just didn't agree with what you said and there was enough public data here to back up what I said and I was hoping you would search rather than have me go find it all but no big deal.
Everyone makes mistakes and I have made quite a few and been taken to task about them so it's all good.

mobil 1 0W-40 is the only oil i'd run if i can't get GC 0W-30. i would say do not run any mobil 1 30 weights in an LS1 engine. they're too thin. they're closer to a 20 weight. they just plain don't offer great protection. mobil 1 0W-40 is, like all mobil 1, on the thin side, so it's actually more around a 30 weight oil. 0W-40 mobil 1 is about the same thickness as GC 0W-30 for point of reference.
whatever you do, don't run any redline oils either. redline oils aren't starburst approved. i'd never put non-starburst oil in my engine. it's in the manual.

i can honestly say i wouldn't use mobil 1 5W-30 if it was free. seriously. it's just too thin for our motors. that's why LS1's have the infamous "ticking". the oil is just too thin to muffle the sound. switch to a thicker oil like german castrol 0W-30. the tick will subside, if not completely disappear. i make it a goal to try and convince as many people as possible to stop putting mobil 1 5W-30 in their engine. go 0W-40 or get off mobil 1 entirely (5W-40 will also work, though i prefer 0W-40 due to the added startup protection).
i got a question i just changed oil from i htink 5-40 was in there and i put mobil 5-30 synthetic...well now i have massive oil puffing. Could this be from the oil change...i also put sealant on the rocker studs. The oil is really the only thing i changed unless something went horrible in the engine.

again, i'd recommend "made in germany" castrol syntec 0W-30 from autozone before mobil 1 0W-40. it's actually a little cheaper per quart, too. mobil 1 0W-40 would be my second choice, however.

the 2 closest to me "i use the word 'closest' loosely, it's a 50-60 mile round trip" both carry it, but they're big stores. i hear small ones don't. check your local autozone if it's close. if not, i posted a thread in this forum about an online store that sells it. check them out, too!
