I have a 2007 Chevy Suburban which seems to go through a quart of oil every 2 to 3 thousand miles...usually before I get an oil change. There is no evidence of leaking anywhere. What is the problem, anyone know? My email is firstname.lastname@example.org

2007 Chevrolet Suburban 1500 Question: low oil levels

you are burning a small amount. gm says that 1 qt every 1000 miles is normal consumption.
it is 5 years old and this amount of oil usage is not abnormal. you can try changing viscosity to 10-40 and see if it slows down the burning.

thanks for the response! I didn't realize this because every other car I've own did not burn this much oil....I don't notice any blue oil smoke burning while driving. I had a 1999 Chevy Suburban prior to this one and didn't seem to have low oil levels between oil changes. Anyway,it's good to know that this is normal, and not a more serious problem...

No, a quart every 1000 is terrible - Before my '07 Burb I never owned a car that needed oil added between oil changes - some cars got changes every 3000, later I switched to every 5000 - never had a car burn half a quart in 5000. My Burb was burning a quart every 1000. I had ot do the long term oil consumption bull**** with the dealer, go in there once every 1000 miles for 5000 miles before they attempted to repair it (just the diverter fix) then had to go in every 1000 for another 5000 miles before they finally fixed it. They pulled the pistons, cleaned the ring grooves and replaced the rings, pulled the heads and cleaned carbon out of cylinders, replaced three rockers and three push rods and all 16 lifters. I'm seriously concerned that there was more valve train damage that they didn't deem serious enough to repair or that the lubrication failures that lead to all of that valve train damage might not be completely fixed.
MANY of the 07 Burbs have this condition - make them fix it before you hit your 100,000 mile warranty.

When my 07 Suburban was less than 3 years old with 36,000 miles it was going through oil at 1 qt. for 600 miles and no smoke and no leaks----the dealership completely rebuilt the engine and its been fine since---uses no oil at all now----glad it was under warranty----doesn`t sound good for chevys 5.3 engine for 2007
