You should be fine with either the Mobil 1 or RP

The way it moves in cold temperatures (w stands for winter). When cold, 0w30 will move like a 0 weight oil and once it warms up will be a 30 weight, same thing for 5w30.
Mobil 1 5w30 or 5w40 should work fine for you, I would recommend the 5w40 for the winter and when warmer temperatures come the new 15w50 that Josh is using works very well, I use it in my car during summer months also. If you feel like spending the money get royal purple.

Using the Mobil 1 or Royal Purple will work excellent. The grade of 5W 30 will give you the best protection and better gas mileage. Using the 15W 40 works better IF you have a HIGH mileage engine(over 100,000). Both oils will also last longer between oil recommended oil changes also!

if you have an LS1, DO NOT USE M1 5w30. its the worst oil ever made. do a quick search on ls1tech, and youll see hard evidence. M1 is all marketing, and nothing else. there have been regular dino oils that have out performed M1. M1 has been shown to break down after barely 1000 miles through oil analysis.
you cant go wrong with german castrol. autozone is the only place the carries it. go to your local store and ask them to order some, they usually do. if not, WS6store sells it by the case. royal purple and amsoil are also good.
if you insist on using M1 5w30, i have about 8-10 qts. that i will give to you free of charge.....thats what i think of using M1.

valvoline 85w140

your local habib autozone employee wouldnt know german castrol from a german shorthair. ill look for the part number tomorrow, but to explain to them, just call it castrol syntec 0w30. if you ever do see a bottle, look on the back, make sure it says 'made in germany' on it.
also, try a K&N filter, its what i use. get the longer version then whats recomended for an LS1. its no lower then most headers or cat-back exhaust, and will give more protection and let you run a full 6 qts. a little easier, which is what i always run. i think, ill find out for sure tomorrow, but i think the K&N filter # is 2009

You can do whatever you want, but just about all oil related problems are due to starvation or poor change intervals- not the blend or detergent content or anything like that. With the one major exception being an engine break-in being done with synthetic oil. Use the stuff you want to use but there is no silver bullet oil that is the "best".

yea i called one autozone and asked if they had castrol syntec 0w30 and he said theyll get a shipment in tomorrow so i guess i need to ask for it by name....also i heard the K&N wasnt too good??? well i guess its all preference like everyone says so i think ill try the K&N long filter and see how i like it

i wouldnt believe anyone at autozone. i would have stuck with the 30. and remember its 0w30, not 5w30 that you want. 50 might be a little too thick. could try it for one change and see if theres any differance in valve tap or whatever. personally, id stick with 0w30, its been proved to work and protect.

harm, no. but the 0w30 is safe to use. its a proven oil. the 0w is only for cold temps and start up, which you want. the thinner the better, because it will warm up relatively quickly. the 30 is actually on the thick side of a 30 weight, which again is what an LS1 needs. trust me, go GC 0w30 and dont look back. youll be fine.
