Engine Break-In Procedure
Use only engine oil that meets dexos1 specifications. For track events or competitive driving, use Mobil 1 15W-50 engine oil. Fill the engine with 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 at approximately 1,000 RPM until normal operating temperature is reached. The engine should be driven at varying loads and conditions for the first 30 miles or one hour without wide open throttle (WOT) or sustained high RPM accelerations. Run five or six medium throttle (50%) accelerations to about 4,000 RPM and back to idle (0% throttle) in gear. Run two or three hard throttle (WOT 100%) accelerations to about 4,000 RPM and back to idle (0% throttle) in gear.
Change the engine oil and filter. Inspect the oil and the oil filter for any foreign particles to ensure that the engine is functioning properly. Drive the next 500 miles (12 to 15 engine hours) under normal conditions. Do not run the engine at its maximum rated engine speed. Also, do not expose the engine to extended periods of high load. Change the oil and filter again, and inspect the oil and oil filter for any foreign particles to ensure that the engine is functioning properly.
