Millers CRO 10W40 Competition Running-In Oil

Do I need a special running in oil for a motorsport engine?  Yes, we certainly recommend this.  It is very difficult to get new piston rings and bores to run in on a full or semi synthetic oil. Millers Oils therefore produce a competition running in oil CRO 10w40.  This is a very high quality mineral oil which will protect the cams, followers etc. whilst still allowing the rings to bed in. It can be used for the running in process on both a dyno or on the road.
