are you talking about what 'running in oil' means
it's a type of oil which is for running in an engine. i.e. in the early stages after a rebuild you use it to protect the cams, rings, cylinder bores and so on
(or something more technically accurate than that if you want to get all pedantic but the general idea is right)
so.... beautiful explanation. Thank you very much for you help. Could you tell me some name, link or reference of that type of oil... so I can buy it.
Cheers
Luis
