How do I break in the engine?

If you purchase a new vehicle, you want to break in the engine by driving it carefully at first. For the first 300 miles, you should try to drive it as safely as possible at varying engine RPMs not exceeding 55 mph.

During this time it’s a good idea to do some full-throttle acceleration when safe. This will help break in the engine and allow it to operate optimally going forward.
