Running In Procedure & Disclaimer

Millers Oils Running In oil has been designed to last the full running in procedure. Do not use fully synthetic or semi synthetic oils before the process is fully completed as this can lead to bore glazing.

• When the engine has been built to a high standard, fill with running in oil to the maximum mark on the dipstick.
• Run the engine for approximately 500 miles on the road or alternatively on a test bed/rolling road.
• Indication that the procedure has been completed includes:
• Compression ratio to manufacturer’s specification.
• Increased engine performance e.g. acceleration.
• Improved efficiency.
• Reduced oil consumption.

Although Millers Oils provides a general guide for the running in process, the onus lies with the engine builder to ensure that the correct procedure per engine is completed effectively. When Running-In Oil is being used, its limitations should be stressed to the actual driver of the vehicle and that it should be changed after approximately 500 miles.
