Learn All About Lawn Mower Oil

If you’ve changed your lawn mower’s oil, you’ve no doubt seen listings like “SAE 30,” “10W-30,” “5W30” and so on and so on. But do you know what those listings mean?

In this issue, we’ll talk about your lawn mower’s oil.

What do those numbers and letters mean?

The classification of motor oils is the brainchild of The Society of Automotive Engineers, and actually focuses on the viscosity – or thickness – of the oil.

The first number will give you an idea of how thick the motor oil is. The higher the number, the thicker the oil. For example, 0 is essentially like water but 10 is more like honey.

The “W” stands for winder, and is an indication of the thickness of the oil in colder conditions. The letters “SAE” indicate that the oil meets the standards of The Society of Automotive Engineers.

In some cases, thicker oil is a good compensation for gaps in the rotating shaft of your mower that have developed over the years.

How often should I check the oil of my lawn mower?

It’s best to check the oil level in your mower just before each time your start the engine. To get the most accurate reading, check it when the engine is cold.

To check it, follow these steps:

  1. Locate the oil fill cap (on newer models, the words “oil” or “fill” or even an oil symbol will be stamped on the plug);
  2. Before removing the cap, use a clean cloth to clean debris from around the crankcase;
  3. Inspect the oil by removing the dipstick, wiping it with a clean cloth, reinserting it and removing it again (the oil should never be above the “Full” line or below the “Add” line on the dipstick);

How do I change the oil on my lawn mower?

If you need to add oil, be sure the engine is off and the sparkplug lead is disconnected.

After that, follow these steps:

  1. Locate the drain plug (this is typically below the deck);
  2. Drain the oil by positioning an oil pan or empty bottle beneath the mower and tilting the mower deck;
  3. With a socket wrench, turn the drain plug counterclockwise;
  4. Add new lawn mower oil but avoid overfilling the crankcase; and
  5. Replace the oil plug, re-attach the sparkplug lead and run the engine on idle.

    Juniper Landscape Company has been fantastic. Before them, we ran through three or four other lawn and landscape maintenance companies who did spotty and sometimes outright poor work, were not always reliable and who ended up creating problems for us in a variety of ways. That experience led us to subscribe to Angie's List... Read More
