[QUOTE="HLN A55, post: 6710, member: 46"] Interesting thing happened... I have an '01 Z06 that (going by the manufactured date) should be plagued by the well discussed oil consumption issue all over the internet. For those that aren't familiar... in the first year of production there was a condition created by running the engine at higher rpm (typically above 3000) under light load that would cause the primary (i think it is) piston ring to flutter slightly and consequently cause a temporary period whereby the engine would consume some oil. GM fixed the issue by using a different profile piston ring in subsquent LS-6 engines. Some '01 motors were replaced under warranty while others weren't. For the first 1,500 km's or so I noticed that I was going through about a liter every 1,000 or so km's which was quite high. Being that the engine only has 35k on it I have no intention of replacing it or tearing it down so I just figured I would either alter my driving style and/or keep checking the oil. Here's the interesting part. For the last 2,000 km's the engine hasn't consumed even a DROP of oil.... The only thing I can think of is that before I bought the car, it essentially sat (with no km's and limited running) for over a year and somehow the engine has "re-seated" itself or established a fresh wear pattern (although highly unlikely or even possible). Does anyone have any idea how this may have fixed itself or was I paid a visit by the engine fairy??? :D [/QUOTE]
