If your going to take the time to disagree with everyone at the least you should post up facts along with references to all of your facts,
and arguing? last I checked this board is designed to help all members.

I already posted where to get all the facts. bobistheoilguy.com You need to get your facts straight. Use whatever oil you want in your own car but you're spouting BS based on NOTHING but opinion. This subject has been beaten to death and that is why I chose not to argue yesterday. Do a simple search and you'll see.

Nice blanket answer, i saw the site, can you take the time to post the FACTS that you are using to back up your opnions. I am quite sure your expertise would be good for all, maybe we can get it sticky for all to read

Ok, first go here...

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?

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.

Mobil 1 5w-30 for me.

ChocoTaco369

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.
What shouldi put in?

ChocoTaco369

yes. mobil 1 5W-30 is a POOR oil choice for an LS1. it's more suited for new 4 cylinder engines that require very thin oil. use either mobil 1 0W-40 or, of course, German Castrol 0W-30, the best oil for our engine. i say use 0W-40 mobil 1 over 5W-40 because you're getting the same operating thickness and protection as 5W-40, you just get better protection in startup and cold weather.

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.

Traitor

Would you guys say 5W40 would be best for hot weather (FL)....no fear of cold down here.

ChocoTaco369

0W-40 still. the 0W allows for better startup protection. even in 100 degree weather, remember 100 degrees is ice cold for an engine.

i'd still say GC 0W-30 over mobil 1 anything though

Traitor

The GC, do most autozones have it or will I likely have to get it online?

ChocoTaco369

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!

M1 0W-40. I thought about GC but the autozone close to me only carries 2 quarts and they havent stocked up for half a year so I gave up on that.
