Description

A mineral based running in oil for vintage and classic engines designed for the initial running in of re-built engines.

Application

Use for initial running in of re-built engines. Formulated for running in on the road. Can be used for test bed running. Run engine at peak torque to ensure maximum bedding-in of piston rings. Drain and refill with the Millers Classic lubricant.

User Benefits

• High quality mineral oil formulated to solve the problems experienced when reconditioned engines do not bed-in.
• Provides full protection to highly stressed valve gear and associated components whilst allowing piston rings to bed in against the bore.
• Good running in will optimise the performance and fuel efficiency of a reconditioned engine.
• Very low leak down (4%) obtained after thorough running in process.
