Oil Filter
| Brand | Part Number | Markets | Notes | Buy |
|---|---|---|---|---|
| MOBIL | M1210A | 🇲🇽 MX | Extended Performance | View on Amazon |
This table covers the oil filters that screw onto this engine's filter mount. Typical signs include low oil pressure after a service, or a filter that will not spin off because the old gasket stayed on the block. Lube the new gasket and tighten to the spec on the box; a double-gasket install dumps the sump on the first drive.
