How Many Miles to Break In a New Car Engine

Breaking in a new car engine is an important process that helps to ensure that your engine will last for many years to come. During the break-in period, the engine’s components wear in and mate together, creating a smooth, efficient running surface. This process can take anywhere from 500 to 1,000 miles, depending on the type of engine and how it is driven.

During the break-in period, it is important to avoid:

Hard acceleration
High speeds
Towing heavy loads
Idling for long periods of time

Instead, you should drive your new car in a variety of conditions, including city and highway driving. This will help to ensure that the engine’s components wear in evenly.

Here are some specific tips for breaking in a new car engine:

For the first 500 miles, avoid driving at speeds over 60 mph.
Vary your speed and avoid driving at a constant speed for long periods of time.

Change the oil and filter after the first 500 miles.

By following these tips, you can help to ensure that your new car engine will last for many years to come.
