Help me find an oil! (complicated)
I hate GC 0-30 because in my 5.0 it sucked a TON of it into the intake and it used it at a bad rate. Almost like M1 10-30. I want: A full synthetic oil that can be purchased at auto-zone/wal-mart and meets GF3/GF4 specifications. I want a weight with a 100CST of 12.6-13.5 and I would like 0-40 or 5-40 weight.
Sorry Patman, I just dont like GC. I have heard too many 50/50 posts and I myself didnt have any luck in my other car with it.
PS. when I bought the car it was QUIET! it had a really heavy oil. THis 10-30 syntec uses no oil, but tis a tad louder. I want something a bit heavier.

I've been very happy with M1 0W40.
No burning.
Engine noise reduced significantly over the M1 10W30.
Oil pressure up about 3-5psi over M1 10W30.
Autozone almost always has it in stock.

I am using the 10-30 right now and DAMN, that stuff is thinner than I thought Help guys, what on that list would the LS1 like the most? (no wonder I have a minor minor sewing machine sound kinda,it wasnt a pushrod/rods, they ALL are doing it and this is why!! 10.1 @ 100*C !!!

Switching from M1 10W30 to M1 0W40 cut my valvetrain noise in half, maybe more. I don't think any oil will make the LS1 valvetrain 100% silent, every one I've ever owned/heard makes a slight sewing machine sound no matter what oil it's got, even when stock. But M1 0W40 will get the motor as quiet as you could hope for.

Yes, I know it's NOT a Wally World/Advance/AZ item, but if you're worried about the 100 degree cst you cannot go wrong with either Redline 5W-40 or Amsoil 5W-40. Short of that, the Pennzoil Platinum is great "off the shelf" non "boutique" oil, but I'm not sure of the 10W-30's cst (it's probably not as high as you want), and I'm told that any of their heavier weights are NOT the same excellent formulation (but I'm not positive on this, maybe Patman can chime in with some definitive answers on this??).

The 10w-40 is 14.4 @ 100 if you are looking for heavier.
