REFLECTOR: engine break in

[Lou Stedman]

I just had all four cylinders on my o-360 milled out 10/1000 and new pistons and rings. The engine only had 400 hours on it since major. One guy tells me to run my normal oil. Another tells me to run mineral oil. Another tells me to run mineral oil for ten hours and then go back to regular oil. Little confusing. I would welcome thoughts from the group. Thanks
