Good day everyone. I have a question. I am in the process of purchasing a 2016 Z06 new but with 292 miles (the dealer drove it from another dealer).

Given the amount of miles on the car, I wanted to see if there was any way for the dealer to verify that the car has been used appropriately (specifically the break-in process of not going above 4K RPM for the first 500 miles)?

I asked the dealer but also wanted to ask on here some a lot of you are very familiar with what is possible.


Thank you

I'd imagine that those 290+ miles were driven very hard. I bought my C7, 260 miles from home, and even though its my car, I was constantly going driving the car more aggressive then I should. Too hard to resist, and the open roads, leading to quick acceleration.

Thank you for the reply. Just asking about whether there is any information the dealer can pull (through diagnostics) to gauge RPMs, etc.

No. With luck they gave it a proper break-in by running the chit out of it.

There is nothing wrong with running it hard during that period. I would change the oil though. I change the oil in the first 150 miles on a fresh motor to get the break in metal shavings out.

Ref #5 - On your vehicle it is your money, your call, however, the manufacturer's recommendation is to change the oil on dry sump engine at 500 miles & I would follow this.


In addition, manufacturing process on new engines is much better than 50 years ago, & machining flakes in the engine are very rare. On most vehicles (except for Corvette dry sump engines) it has become unusual to recommend changing oil at low mileage. I had a 2001 BMW 3 series that the manufacturer recommendation was 15,000 miles, which I did follow since it was a 3 year rental & BMW covered the oil changes. I will admit if we had purchased the vehicle with the intent of keeping for a longer time than 3 years I probably would have changed the oil at about 2,000 to 3,000 miles. Of course above comments are predicated on synthetic oil usage.

I'm having a built motor done. This was the recommended break in of the builder. Run it hard and change the oil soon. I'm also having an oil analysis done after first oil change in 100 miles.

The mileage is from them going to pick up the car for you? Myself, I would just drive it till it got to the 500 mile oil change and change the oil. The car is under warranty so if there is anything wrong with it GM will fix it. One thing to do is check the In Service Date. Will it be on the day you buy the car or when it was at the other dealer?

Perhaps I am an untrusting person, but I see a significant possibility that the delivery driver might entertain himself a bit with the car. I would worry about break-in rpms exceeded and generally aggressive driving to include hard shifts and even burn-outs. Did he vary rpm's? If an A8, did he keep it out of V-4 mode? A cause for concern if it were my new car.

The car was transfered to the dealer I am purchasing from prior to me even knowing about the car. The in Service Date would be the day I buy the car. I have actually decided to go through with sale. I am finalizing the deal now. Guess I will see how it all turns out in the long run.

You can check the engine hour and lifetime revolutions and with some math draw some conclusions
