I'm not sure if M1's light weight really makes that much of a difference as I once thought. Analysis doesn't show this. RL does have higher HT/HS though. Patman's right though Terry has said RL is great for this.
Why not M1 0w-40 then or a mix of 10w-30 with 15w-50?

Best, price no object? I'd have to say Red Line.
If there's an oil better than Red Line it's something fairly exotic like Motul or Synergen ... but Synergen seems to like awfully thin weights for more power at the expense of protection.

Strange you should mention Motul. I was at Autobarn on Sunday checking if we have Pennzoil High mileage (don't) and found shelves full of Motul. A large range in 5 litre plastic jugs and even metal cans of racing oil (very expensive). Anybody know anything about Motul?
I think it all depends on your particular LS1. My 02 LS1 did not consume any noticeable amount of M1 10w-30 SS in a 3k drain interval. I've since stocked up on Schaeffer #703 10W-30 and am currently using that. However some LS1's drink Mobil 1 like it was a free $2 pitcher of beer!
Yeah, why does Corvette factory fill with Mobil 1 5w30? A guy I work with has a C5 ls1 and he uses Mobil 1 and dosen't burn any??? I hear all Porshas(sorry spelling)and Vipers are factory filled with Mobil 1. 3 totaly different companys are using Mobil 1,they must know something! Why dosen't Mobil just thicken up the oil a little?
