How to Break in a New Engine

There's nothing quite like the feeling that comes with buying a new vehicle, except perhaps the trepidation that you'll do something wrong and ruin the new engine. You'll be pleased to learn that today's engines don't require a long and complicated break-in period. By following a few guidelines and using common sense, you will have your new car broken in and ready for many years of reliable service on the road in a short amount of time.

Instructions

1. Keep the majority of your driving speed under 50 mph for the first 60 miles. After the first 60 miles, speeds from 50 to 55 mph are recommended.

2. Drive your vehicle in a moderate fashion for the first 300 miles.

3. Briefly accelerate to full throttle when driving at the optimum (50 to 55 mph) speed.

4. Avoid wide open acceleration in low gear, as engine damage can occur.

Tips & Warnings

• Check your engine oil frequently in the first 3,000 miles of operation, as new engines may consume oil. Make sure to use the recommended oil type if you need to add oil.
