Description
Millers CRO 10W40 is an oil designed specifically to aid the running-in process of rebuilt competion engines by providing full protection of highly stressed components whilst allowing optimum bedding in process for piston rings to the cylinder bore. It is not recommended that synthetic or semi synthetic oils are used for bedding-in, as they can be too slippery.
Suitable for test bed running up to 5 hours or for 500 miles on the road CRO 10W40 also allows for short burst runs at full engine load.
It is recommended that once the running in process is complete, the oil system is flushed and the oil replaced with the correct grade specified for the engine.
