Purchased used 2001 Z28 with 22K miles. Changed the oil to 5w30 Mobil 1. Changed it again at 26 and 30K respectively with the intention of regular changes at 5K mile intervals. Now has 32,400 miles on it, the LOW OIL warning light came on, checked it and it was 1 1/2 quarts low. After doing some initial searching on the web this may not be an unusual problem and it has something to do with the rings. Called dealrship, as it is still under bumper to bumper warranty, they want to change back to conventional oil as they suspect that the synthetic may be the cause. Been running synthetic in nearly every auto that I have owned and NONE have ever had a problem with oil usage between changes. I thought GM shipped the vette with Mobil 1 from the get go. Anyway, I don't buy the answer but am willing to do what the delarship wants so as to have a record of what is going on. Would appreciate any input as I plan on keeping this car forever, if I can.

Triple black convertible with almost all the options.
