Replacement engine oil

[Soundguy]

that's the kind of answer i expected.

i have antiques that don't evaporate oil like that gm does..

heck.. I don't have ANYTHING that evaporates oil like that gm does. NONE of my gas or diesel engines consume more than 1/3 their sump fill during a short run term oil change, like 3000m../equivalent etc..

Go with an oil rated for pre 2007 diesels.

i'm curious as well.

I find it non flattering that gm calls it normal to drink a couple quarts per 3000m on that engine....

Yea, IMHO it is not NORMAL to have to add oil between changes in anything unless the engine is operated in severe service. My 7.3l PS will not use but maybe a quart in 5K miles UNLESS I am plowing then it will use about 2 to 3 quarts. I attribute that to no turbo boost not sealing the rings when plowing. On all my GM's I had only 1 oil burner that was bad and it was a 98 5.7L in a 3/4 ton. Very very loose engine. CJ

yep.. at that oil consumption rate.. it reminds me of a 2 cycle..

My 475 Cat in the big truck (almost 625000 miles) only uses about a 1/2 a gallon in 30000 miles.
The 4 Litre in my Jeep with 177000 miles on it never uses any oil between the twice a year oil changes. I run 10W30 year round.
I think that there is something wrong with that GM.

I think it's wrong.. however gm says it's book spec for that one.. did it since day one. I know MANY people that report the same thirst on those engines...

Mine never used a drop until it hit 250,000kms, now it uses a little. It is an 04 5.3L
