Formulated for use during the running in period for re-built or overhauled engines, especially recommended for the first 400 - 600 km. It successfully prevents “bore polishing” and simplifies the running in process of the piston and piston rings. For additional wear protection in the run-in phase of large-volume OHV-US-V8 Flathead engines, see Rektol ZDDPower.
