Filed Jul 9, 2004 · Engine · 3,900 miles · CA

At 3,900 miles my new car was down 1quart of oil. Upon questioning I found this was common problem with 2001 corvettes. At 15000 miles gm replace pistons but said that it is acceptable by gm stardards for the corvette to burn a quart of oil every 900 miles. However they won't give me information in writing only to my lawger which I don't feel needed yet. I also had a friend who has same year corvette as mine and he two is burning oil. It is a know problem even in gm web sites for it mechanics. Please help I'm tired of checking oil and reporting consumption to dealership I didn't purchase a 50,000 car for this.

Concerned about potential fire from catalytic converter. Also concerned about environmental effects. Chevrolet needs to take positive action to resolve issue.

Excessive engine oil use--1 1/2 qts per 2000. Miles chevrolet advises that normal oil consumption is a qt every 700 miles????? Chevrolet has a upgraded set of rings that stop the excessive consumption but they stonewall customers by telling them that consumption rates are normal at 1qt every 700 miles. Is this not a safety issue since the excessive oil soaks the catalytic converter, thus causing a fire.

This car has burned several quarts of oil since I've owned it. It burns approximately 1 to 1 1/2 quarts every one thousand miles. The dealership said the 2001 corvettes all have this problem because of bad piston rings. They siad some cars consume as much as 3 quarts of oil per 1000 miles. The amount of oil burned is relative to how hard the car is driven. There are know replacement parts available at this time.
