What is considered high mileage for an oil change?
It all depends on how the vehicle has been driven and maintained. Some people might consider switching to a high mileage oil at 200,000 miles, while others may want to change to a high mileage oil at 80,000 miles. For the average driver, anything over 100,000 miles could safely be considered a high mileage vehicle. How many miles is a high mileage oil change good for? It used to be normal to change the oil every 3,000 miles, but with modern lubricants most engines today have recommended oil change intervals of 5,000 to 7,500 miles.
