I agree that there probably is not any kind of specific 'break-in" oil used from the factory, but there clearly is an extra additive installed on the new engines, most probably assembly lube. The smell (obvious EP smell) and appearance (kind of murky and sticky, not like oil alone) of the new oil in a new engine is a pretty good tip-off.
Full Answer
Do you need break in oil for a new engine?
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.
What kind of break in oil should I use?

What is break in oil?
Break-in oil uses chemistry to smooth the load-bearing parts in the engine. Smoother surfaces can carry more load, exhibit less material fatigue and reduce friction. A proper break-in oil is formulated from the ground up to be a break-in oil.
When did break in oil start?
Break-in oils have existed long before the flat-tappet cam break-in fiasco of the mid-2000s. There is even a chapter dedicated to break-in oils in the “SAE Lubricants Handbook.” It was commonplace for OEMs to use break-in oils before car leasing became popular. As the EPA fuel economy requirements tightened, the need for less maintenance and better fuel economy ended the use of break-in oils as factory fill in new vehicles.
Why are race specific oils so high in ZDDP?
Marcella says, “Most race-specific oils have ZDDP levels that are too high to allow the removal of surface asperities required for proper break-in and also contain higher levels of other surface-active chemistries that will also prevent removal of said asperities. ”.
Why do break in oils have higher levels of ZDDP?
Because break-in oils are also designed to protect camshafts and valvetrain parts during break-in, they typically contain higher levels of ZDDP. The extra ZDDP in break-in oils prevents scuffing of flat-tappet cams and galling of pushrod tips during initial break-in.
Why are break in oil and race oil different?
Driven Racing Oil’s Lake Speed Jr., says that break-in oils and race oils differ dramatically in terms of chemistry, and that is because they have very different jobs. “While the race oil is designed to reduce wear and increase horsepower, the job of the break-in oil is to allow a controlled amount of wear. As such, race oils are loaded with friction modifiers and other components that reduce friction. On the other hand, break-in oils don’t contain friction reducers. Piston rings are especially sensitive to low friction oils during break-in. For these reasons, break-in oils are typically petroleum-based (non-synthetic) and don’t contain friction modifiers.
How to reduce oil splash on camshaft?
Using a windage tray, or modifying connecting rod side clearances for less oil splash , reduces the amount of oil that reaches the camshaft.

What is actually being done during engine break-in?
What is actually being done during engine break-in is fairly simple – it’s the controlled bedding, or wearing-in, of the new piston rings on the hone of the cylinder walls. “We are trying to bed those rings so that they achieve a correct seal against the cylinder walls, and we have a relatively narrow window in which to do this,” relates Simon. “Once we achieve that seal, we end up with an engine that creates good power, has low blow-by, and has low oil consumption.”
Does cross hatching oil retain oil?
The proper cross-hatch pattern not only retains oil throughout the life of the engine, but the rough finish acts as a file to properly bed the rings in during the break-in process. However the sharp edges only last a limited amount of time.
Can you use synthetic oil to break in rings?
Common high-performance synthetic oil is so slippery it will actually inhibit the wear required to bed the rings in. So you don’t want to use super slick full-synthetic oils to break the engine in,” reveals Simon.
