The break-in — or mechanical run-in — period is designed to begin to wear the engine evenly and smoothly with low, consistent pressure, normal operating temperature and smoothly flowing oil. The goal is to get the engine's piston rings, which expand, contract and flex, to seat properly on the cylinder walls.

.

Also asked, is engine break in necessary?

In general, people no longer break in the engines of their own vehicles after purchasing a car or motorcycle, because the process is done in production. It is still common, even today, to find that an owner's manual recommends gentle use at first (often specified as the first 500 or 1000 kilometres or miles).

Furthermore, how long do you run break in oil in a new engine? On freshly built engines, you'll need to change your oil and filter much more frequently. After using a break-in oil, you should change your oil at 50 miles, 500 miles, and 1,500 miles. Again, at 4,000 miles or so, it's fine to switch to a synthetic oil if you choose.

Keeping this in consideration, what is the break in period for a new engine?

Most experts consider the first 500 miles as a reasonable and sufficient break-in period. The reasoning behind this practice is that keeping revs relatively low helps the piston rings seal against the cylinder bores properly.

What happens if you don't break your engine?

If there are imperfections in the pistons or the cylinder walls from the manufacturing process, working the engine too hard and too soon can wear down those imperfections too quickly. That leads to "hot spots" within the engine's cylinders, which can cause problems in the years to come.
