A regular oil change can greatly enhance the performance of your lawn mower.

If your lawn mower doesn’t have a drain plug you have to drain out the oil the classic way by tilting the lawn mower on its side and catching the oil with a drain pan.

When the oil is completely drained out, wipe the mouth of the oil reservoir and put  the mower back on its wheels  and pour in the new oil.

Make sure you use the right type of engine oil as specified on the user manual and use the oil cap dipstick in your oil measurement. Avoid going over the full oil capacity by checking the dipstick.
