If you maintain a Subaru Outback, Legacy, Impreza, Forester, XV Crosstrek or Ascent, using the manufacturer’s specified oil filter and crush washer helps preserve oil flow and filtration performance. Subaru updated its filter lineup, so the unit you take off your car may look different from the new genuine replacement.

How often should I change the oil and filter, and why use the genuine part?

Genuine Subaru filters are engineered to trap microscopic particles and protect oil passages, ensuring the vehicle’s lubrication system performs as intended.

• Typical service reminder: every 6 months or 7,500 miles, adjust per owner’s manual
• Factory filter designed to capture microscopic contaminants and dust
• Using the correct crush washer helps prevent oil leaks at the drain plug

• Available pack options: 1, 2, 3, 6, and 12 kits
• Bulk packs suit professional mechanics and multi-car households
• Each kit includes one filter and one crush gasket for a complete drain-and-filter service
