Re: 2002 ZL1
Hello Rob: Chevy has had a number of problems with excessive oil comsumption. The 2001 LS6 engine created many complaints. What made it difficult to figure out was that some Corvettes were fine and others were using too much oil. They actually bought some cars back from the dealers that were using too much oil. When they tested the cars they could not duplicate the oil comsumption problems. To better understand the situation they got detailed reports from the owners on HOW they drove their Corvettes. Only then was it determined that some owners liked to drive the cars hard at high sustained revs in town and NEVER shift out of first gear. It was thought that this put an unusual load on the engine and caused the rings to flutter resulting in excessive oil consumption! The LS6 for 2002 has a new ring design that has proven to be more effective in this regard. Still a difficult situation for some '01 owners who don't want the local dealer opening up the engine on their $50,000 dollar Corvette!
