Pour 4 quarts of 10W-30 oil* into the engine. Use one hand to stabilize the funnel to help prevent spills.

* (Check your owner's manual for correct amount and grade of oil. My 1991 Honda Civic takes 3.2 Qt of 5W-30.)

Consult your owner's manual if you think your operating conditions call for a different oil viscosity.

Remove the funnel and place the oil filler cap over the oil filler hole.

Turn the oil filler cap clockwise until it is snug.
