Do you need break-in oil for new engine?

Do you need break-in oil for new engine?

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.

How long do you run break-in oil in a new engine?

Depending on the application, break-in oil is used for 500 – 1,000 miles, or 10-12 full heat cycles, where you allow the engine to reach full operating temperature and cool down completely between cycles. Use engine break-in oil only long enough to seat the engine.

What oil is best for engine break-in?

Use a 5w-30 or 10w-30 motor oil with an engine break-in additive (ZDDP or zinc camshaft additive), especially with flat tappet camshafts.

Can I use synthetic oil to break-in a new motor?

Today, most new engines come from the factory with synthetic oil. However, these engines were broken in prior to being installed in the vehicle. Engine technology has improved to the point where breaking in an engine is not as critical as it used to be. These newer engines can be broken in using synthetic oil.

What happens if you use synthetic oil for break-in?

It is actually possible for synthetic engine oils to prolong the break-in time and glaze cylinders, which will incapacitate the ring. Due to the fact that synthetic engine oils have lower friction coefficients, they are inherently less effective.
