using a quart of oil at about 1500 miles..?
Go do an oil change and put in NON-synthetic Castrol GTX 20w50.......you should be good with that and burn way less. As for protection...better than the M1 or at the very least the same. And you will save a bunch of coin.....
*****This is considering that your engine is mechanically fine and your PCV system is ok.*****
.
Next oil change, do what I did....so you don't drive yourself nuts thinking you're burning more than you are. Know exactly what you're burning.
As you put in the new oil, put in 3 quarts real fast......but then pour in the rest at 1/2 qrt intervels. Each time wait about 15 minutes, then pull the dipstick out and with a file make a little hash mark. Do as many as you want or do them in 1 qrt intervels.......however accurate you want to be.
Then later on when you check your oil when the engine is cold and has been sitting all night......you will know exactly what you are burning in 1,500 miles.

20w50 is great for these engines...regardless what the manual says or what anyone says. My 427ci has 150,000 miles on it, and thats the only weight oil its ever had. BUT....its pretty thick for cold places maybe, but I don't see why it would make much of a difference. Hell, it would just stay thicker which is what you want in an old worn engine. If it sits for a long time it will also cause oil to stay on the bearings and parts if its thick....
PCV valve might be stuck open........put a new one in, they're like $3.00. I personally put a variable valve on mine PCV line. I can set it to be as strong as I want or as weak...or turn it off completely, no vacuum sucking crankcase gasses and oil into the intake at all. I have it on a very very low setting right now, it barely pulls crankcase gasses, but just enough to pull out the bad gasses.....but zero oil.
See the "T" valve with screw in it....I can set it to any suction strength I want. The factory suction is WAY WAY too much for any engine. I've got a totally modded PCV system and lines....but anyone can put one of these right before their PCV valve and adjust it from there. I think you should at least turn the suction down to half what it is.
((whatever you do....stop using synthetic oil))

They take 5.5 quarts or 6 if you put an oversized filter on them...
The PCV system is the root of most oil consumption problems with the LS1.
