What my dealer said about the oil consumption problem

1156 Views 5 Replies 6 Participants Last post by  ZO6SPEED
On Tuesday I'll drop off my Z06 for multitude of problems:

1. Oil consumption test
2. DIC is dead (I'm flying blind)
3. Seat belt retractor needs to be replaced
4. Alignment is out (after 5K miles)
5. Strange clicking sound in engine

OK, I'll stop ranting about the quality problems.

Here's the useful bit you might want to know: My dealer was well acquanted with the problem, and said that it's critical to have a record of the oil consumption problem, because my dealer will report this to GM. Down the road, if the oil consumption ever falls below GM's absurd "within range" levels (around 1 quart every 500 miles or so, I'm not sure exactly), then I'll have it on record that my car was consuming a lot of oil, and this increases the likely hood that I'll get a free repair even after my car goes out of the 30K warrantee.

So, while I know the oil consumption test won't help me now, it seems like it could help me later, at least according to my dealer.

Any comments?

I am a owner of a Z06. Although I only have 400 miles on it, and am not experiencing problems as of
yet, I am concerned about the excessive oil consumption I keep hearing about on various corvette
sites. What's the story? Does the Z have bad rings? Does GM have any plans to address this? If so,
what? Please let me know, for over 50k (out the door) I would like a answer, thanks.

Now there's a typicak BS corporate response.
Document...Document...Document!!! If you want to build a case, then DOCUMENT EVERYTHING!! That is the key!!
I have seen only a small percent of the members here complain of the oil consumption problem. My impression is that most say they wait for a warning light and proceed from there to add oil. Of course, if I were an owner who was having the problem it is WAY too high a percent. I suggest you monitor your oil normally and not get too upset until you experience a drop.
It is amazing that the response could be so long without saying anything. The term oil use or consumption was never even mentioned. My ZO6 uses a quart of oil every 400 miles.
