(b) Reinstall the drain plug and fill the engine with oil until it reaches the upper level on the oil filler cap. OIL DRAIN PLUG ■Use fresh and high quality lubricating oil to the specified level as directed on page 8. If contaminated or deteriorated oil is used or the quantity of the engine oil is not sufficient, the engine damage will result and its life will be greatly shortened.
