2. Clean the area around the dip stick (C, Figure 29).
3. Remove the dip stick (C) and clean it with a paper
towel.
4. Insert the dip stick back into the engine, and push
firmly into place.
5. Remove the dip stick and read the oil level. The oil
level should be between the “F” and “L” marks (D). If
not, add oil according to the oil recommendations

two minutes.
5. Using a drop of oil on your finger tip, wet the rubber
gasket on the bottom of the new filter.

the filter base. Turn the filter clockwise until the rubber
