In owners' own words
Excessive oil burn with no warning of low oil until about one quart left in engine. Only check engine light came on. Yes the manual says check oil at every fill up but after owning many cars over 38 years without this problem it would seem the manual was written to protect gm. I would not have purchased the vehicle if I knew I had to put in a quart of oil every 1500 miles. Google this. Im not the only one. Engine · reported at 40,000 miles
