No more burning oil! Hey guys, I bought my 99SS from a guy in CT about 5 months ago. I drove it for about a month and the low oil light poped on, so i go to check it and sure enough it was over a qt low. SO I said to myself, it must have just been old oil and i went ahead and changed it.
I put M1 5w30 in it and figured that was the end of it, the car only had 37k on the clock. Well sure enough, a month later it came back on! Now I was scared, I added a qt and watched it well, and it slowly burned away everytime.
Well, as a last resort I tried something I had never used before, on my next oil change I used castrol Syntech 10w40, and at the same time i added some c2 engine oil additive, it is supposed to stop oil burning. Well, it has been a thousand miles since then and I am still full to the top! God i am so releived, that 5w30 m1 seems to be thin. I would recomend this to anybody who is burning oil.

yea, I think the thicker oil has more to do with it than the additive, but im sure it didnt hurt either. All I know is it feels alot better knowing my car isnt chugging down oil anymore!
In many cases simply switching from the thin M1 5w30 to a thicker oil (most notibly GC 0w30) will reduce oil consumption. The LS6 PCV mod, and the catch can are also helplful.

I run 0W40 M1 and have 0 problems. Having owned multiple LS motors, after a month or so, I always make sure I check the oil on the vette. Ammazingly enough, it burns no oil.
Now my Z28 01, was a different story but greddy catch can cured that. Now for my new 6.0, I'm putting on a LS6 PCV system + catch can (For TB only).

GC 0w-30 can only be found at Autozone.

i believe that GM says that it is acceptable for Gen3 engines to burn up to 1 quart of oil ever 2,000 miles.
i was reading about it at work (i work at a GM dealership) when i was diagnosing an oil consumption problem on a 5.3L truck

If your ls1 has HIGH oil consumption the issue you have is with the engine NOT the oil.
I have owned 3 ls1 powered cars and run them an everything from 0w-30 to 10w-60 just to compare.
Can't honestly say in a controlled blind test i could tell the difference between any of them for engine noise or oil consumption.
My current 2005 ls6 runs on Mobil 1 0w-40 with M1 filter and uses no oil between OCI's at 10,000klms.
I use the 0w-40 because the spec sheet tells me it is one of the top 3 fully synthetic oils on the market available to me at this time.
Oil consumption will always vary between engines but if its high its an engine issue.Heavier oil is just treating the symptom not the problem.
