Engine Break-In Procedure

Use conventional or break-in oil (non-synthetic) for the first 500 miles of operation. Do not drive for long periods at any single speed, always vary your speed. Do not tow a trailer or put other heavy loads on the vehicle. Check the engine oil and coolant levels daily. 

At 500 Miles change the engine oil and filter using conventional (non-synthetic) oil. Check fuel and ignition settings; adjust valves (where applicable).

After the first 5,000 of service synthetic engine oil may be used. Follow your vehicle owner’s manual for service intervals.
