I have a newish vehicle and I’m trying to determine when the break-in period ends. The break-in period for this vehicle is approximately 1,000 miles (stay well below the red line, no sudden stops, no towing, no engine braking, no cruise control for long periods, etc). After I bought this vehicle I relocated. In the process of moving, I had driven the car about 500 miles on the highway in three days of highway driving. The brakes weren’t used very much.
Because of those long trips, I’m suddenly approaching the 1,000 mile mark. Therefore, should I extend the break-in period to 1,500 miles because 500 of the 1,000 miles was long trip mileage?
