Engine Break-In

wv dm 16.02

The engine will perform better over time if the guidelines below are followed.

  • Warm up the engine by driving easily for the first few minutes before placing it under load.

  • Keep the vehicle speed at 60 mph (97 km/h) or less for the first 500 miles (805 km).

  • Do not drive at one constant speed, either fast or slow, for the first 500 miles (805 km). Do not race the engine or make full-throttle starts. Avoid downshifting to brake or slow the vehicle.

  • Use the correct gear to maintain the desired road speed without lugging the engine.

  • Avoid making hard stops for the first 200 miles (322 km). During this time, the new brakes are not yet broken in. Making hard stops with new brakes can lead to premature wear and early replacement. This guideline should be followed each time new brakes are installed.

  • Keep the tires properly inflated for the load carried.

  • Check the lubricant levels in the engine and transmission weekly for the first 600 miles (965 km).

Once the break-in period has been met, engine speed and load can be gradually increased.
