Because time is now a factor in the OLM on the new Corvettes, the numbers are all over the place, so it's hard to get an exact number of miles as to how far you could go. Most guys hit the one year mark before they hit the mileage mark, and the OLM will not let you go past one year. Even if you never start the engine, the OLM will hit zero on the one year anniversary of resetting it.
I'm going to drive mine a lot more than the average Corvette owner, so I'll be sure to report my experience with the OLM. So far I have 516 miles on it and my OLM is at 89%, however it dropped from 100% to 91% just from driving it 80 miles home from the dealer and then it was sitting for one month in my garage until the roads were clean enough to take it out again.
