6. | If four numbers or marks (1 to 4 or 6 to 6666) are printed around the outside of the filter, you can use the following procedure to tighten the filter.
- Spin the filter on until its seal lightly seats against the oil pan, and note which number or mark is at the bottom.
- Tighten the filter by turning it clockwise three numbers or marks from the one you noted. For example, if mark 6 is at the bottom when the seal is lightly seated, tighten the filter until the mark 6666 comes around to the bottom.
