I'm 30 hours into my engine break-in. Changed the oil at 5 hours. Going to change it now. In 25 hours it will be time to change to ashless dispersant oil (which one - oh no!). But I will have many quarts of the 100 mineral oil on hand when the break-in is done....
So - do I just stay with mineral oil to 80 hours?
Or - do I go ahead and switch at 50-55 to the new oil and then what?
I suppose there would be no harm in using one of the mineral oil quarts occasionally when a quart low?
