Running in oils
Running in oils
(OP)
Does anyone have some definitive data on the type of oil (Mineral or synthetic) should be used for running in an engine.
my understanding is that mineral oil speeds up the bedding in process. Synthetics slow this down which can lead to oil consumption, but have no hard data to support.

The reason I see that Euro OE's are using Synthetics for Factory fill is that they also have very very long service intervals and NO intermediate first servie. BMW first oil change on many models is 20000Km. No mineral product will last as 20000Km can take 2 years.
You seem to be sticking with the better oil companies there but why the Mobil 15w50, why not Castrol Formula R10w60?
RE: Running in oils
In reality, Mobil 15W-50 does the job and is available at Wal-Mart for a bit under $4 a qt. My days of being sponsored by Empire are long gone and my contacts with Castrol distributors non existant. I race only vintage and no longer contract for other racers, retired ,you know! The cost of oil is no longer a 'secondary' expense. I did try Syn-Tec for a while but I'm back to Mobil 1. So far, so good.

There is a recent trend to more Kw than is needed by anyone, and more importantly, more than can be legally used. In these cases my opinion is that part throttle conditions appear to be leading to oil consumption.
Any thoughts??
Also the current fuel efficient products (ILSAC GF rated) require some FM to obtain their fuel efficiency above the reference oils.
