Engine Break-In Procedure

Fill the engine with Mobil 1 15W50 motor oil and follow the proper engine priming procedure.  Also check and fill as required any other necessary fluids such as coolant, power steering fluid, etc.  

Start the engine and listen for any unusual noises. If no unusual noises are noted, run the engine from idle to approximately 1800 RPM, then 0% throttle back to idle. Perform this sequence continuously up and down until normal operating temperature is reached. DO NOT RUN THE ENGINE AT A CONSTANT HIGH RPM WITH NO LOAD. VARYING RPM, IDLE TO 1800 RPM UP AND DOWN IS ALL THAT IS NEEDED. The engine should be run for one hour without wide-open throttle (WOT) or sustained high RPM accelerations. When possible, you should always allow the engine to warm up prior to driving. It is a good practice to allow the oil sump and water temperature to reach 180°F before applying heavy loads or performing hard acceleration runs. Run 5-6 medium-throttle accelerations to about 4500 rpm and let off in gear and coast back down to 2000 rpm, after each acceleration.  Perform several (WOT) accelerations to 5000 rpm. Allow the engine to return to idle, with the throttle blade shut. This procedure will assist in seating the rings properly.  Change the oil and filter.
