Why is engine break-in important?

Proper engine break-in can help to:

• Reduce wear and tear on the engine
• Improve performance
• Increase fuel efficiency
• Extend the life of the engine

How to break in a car engine

The best way to break in a car engine is to follow the manufacturer’s recommendations. However, there are some general tips that you can follow:

1. Start by driving the car gently for the first 500 miles. Avoid hard acceleration or deceleration, and keep the engine speed under 3,000 rpm.
2. After 500 miles, you can start to drive the car more aggressively. However, still avoid excessive speeding or racing.
3. Vary the engine speed and load as much as possible. This will help to create a good seal between the piston rings and the cylinder walls.
4. Change the oil and filter after the first 1,000 miles. This will help to remove any metal shavings or other debris that may have accumulated during the break-in process.
