Classic SAE 30 Break-In Oil


  • SAE 30 break in oil
  • For break-in on the road, or dyno
  • Change after approximately 500 miles

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 most suitable for the engine. Suitable for limited road use (500 miles) after which it should be replaced with the appropriate Millers Classic Engine Oil. 

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.
