Contributing factors to LS1 oil usage What is it that causes LS1's to be such oil feinds? I have heard the PCV valve is horrible on these cars. I have also heard things such as ring flutter, loose piston/bore clearances. What is the issue in most cases where cars chug 2qts in 3K miles? How commin is usage that bad using a PROPER oil(0 or 5-40)? Sorry for all the dang technical questions as of late but I am planning on buying something here pretty soon (deal on property seems to be going well) and if I am going to drop the $$, I want the facts. Is it poor ring seal or other issues, or PCV or is there a legitimate piston/bore/ring flutter problem. The car I plan on would be 01-02 M6 if it helps. Thanks in advance!

mine used to burn oil fast on m1, a brand switch to rp was all that was needed for my car, the pvc seems to be a big contributor to the oil usage. my intake had oily film on it, so the ls1 pvc isnt the best, i just bought a new pvc valve (they also sell the whole ls6 valley cover and pvc system 100+$ dont remeber exact price) but mine no longer has issues, so the soposedly improved 6$ valve was enough for me.

Was it the RP or the new valve that stopped the usage?

Thanks, Still looking for feedback and all, I am planning to purchase a sports car in the next 6 months and the LS1 is getting top nod right now. Oil consumption is the only thing that is worrying me. My 5.0 sucks 2-2.5 qts in 3K miles and its a new motor with excellent compression test numbers and all that jazz, but it still drives me NUTS!!! I DO NOT!!!! WANT TO DO THIS AGAIN!!!!
I have heard the SHell full synthetic 0 or 5-40 is a good oil too. I know I have used 15-40 SHell in a lot of stuff and it works great. The best success story I have with it is the LT1 TA I woulght a few years ago with 150K miles on it. Owner ran 20-50 GTX. The 15-40 rotella cleaned so much **** out that the filter plopped black pudding out of it during every oil change I did for 2-3 changes (I did it at 3-400 mile intervals to clean her out). Car never used a dribble until I sold it at 170K miles and then it went to a federal impound b/c of the new owners...ermm...life choices.
Edit: when it comes to worrying over mechanical flaws im like a ferret on crack with OCD.

Just convert to the ls6 pvc set up. I was using a quart between changes. Ls6 conversion cleared up and using Valoline 5w30 since I bought it, hell use that brand in all past vehicles.

Amsoil 5w40 here, no noticeable consumption. Stock PCV. As a matter of fact, i'll try to remember to check it tomorrow to be sure. The oil has ~2.8k miles on it.

Mine has never consumed any measureable amount since new. When I had the motor apart swapping heads I upgraded to the LS6 PCV setup since I was in there. Go for an 2002 model, that's your best chance of a non oil burner. 2001's seem to burn oil the worst due to the rings GM used that year.

What rings did they use different that year?
