Grab the yellow handle of the engine oil dipstick at the front of the engine and pull the dipstick out.

Wipe down the dipstick with a rag or towel, reinsert it, then pull it out again to get a an oil level reading.

The oil level should be somewhere between the two holes, which denote the minimum and maximum levels. Add or drain oil as necessary until you have an appropriate level.

Reinstall the dipstick and oil filler cap. Twist the cap clockwise until it is snug.
