Common Lawnmower Questions

Lawnmower Maintenance Kit

What oil should I use in my lawnmower?

Lawnmower Oil

You should use a SAE30 or 10W30 oil in your lawnmower. Double check oil levels before each use – a lawnmower may not smoke or display common low oil warning signs.

Spark Plug


Where is the lawnmower's spark plug?

Spark Plugs

Most Spark plugs are located on the top of the engine

The spark plug keeps the mower running efficiently. It’s not an expensive item to replace – so plan on replacing each year to ensure longevity of the lawnmower.

Octaine Fuel

What octaine fuel should I use in my lawnmower?

Gasoline for Small Engines

Use the HIGHEST OCTANE available at your service station, your small engine will run much better and longer. Ethanol levels in today’s fuel cause it to go bad quickly, so only buy what you will use within two weeks. Finally, get in the habit of “treating” your gas with a stabilizer right at the station. In the event your mower sits for a month, you don’t want the fuel to go bad and cost money.

How do I turn gas on/off on my lawnmower?

Locate the fuel on/off lever.

Most major brands have a well marked fuel lever, close to other operational dials. It will be located below or to the side of the fuel tank.

White arrows indicate off/on switch locations.
