Do I really need break in oil?

New cars and trucks don’t need break-in oil. The manufacturer will typically require you to drive under light-to-moderate load for a few hundred miles, then change oil. After that, you’re good to go. Racers, competitors or gearheads using a rebuilt or new crate engine, however, should use break-in oil.
