The 2020 Crosstrek’s 2.0-liter engine uses Subaru OEM oil filter 15208AA15A. This is the standard filter for that engine family and is commonly used across early-2020 Crosstrek builds. This article lays out the official part number, cross-reference options, and how to verify the correct filter for your vehicle.
Official part number and fitment
The Subaru OEM oil filter for the 2020 Crosstrek’s 2.0L engine is 15208AA15A. This filter is designed to seal properly on the Crosstrek’s oil system and is compatible with other 2.0L Subaru models from the same era. If you’re buying from a dealer, provide the VIN to ensure you receive the correct revision.
Cross-reference options
For those considering aftermarket alternatives, many filters cross-reference to the same Subaru part number but use different labeling. When shopping, aim for a filter with the same thread size, gasket type, and overall dimensions to ensure a proper seal and fit. Brands commonly used by Subaru owners include Wix, Bosch, and Fram; always verify compatibility on the product page or with the retailer’s cross-reference chart.
Tips to verify compatibility
- Check the model-year listing to match the Crosstrek’s 2020 configuration.
- Compare the filter’s dimensions to the stock unit (diameter, height).
- If in doubt, bring the old filter to the parts counter or search by VIN on the retailer’s site.
Conclusion: VIN-based lookups and retailer cross-reference tools help ensure you’re buying the right filter for your Crosstrek, particularly when shopping aftermarket.
Maintenance notes and recommendations
Subaru typically recommends using 0W-20 synthetic oil for the 2.0L engine and replacing the filter at the same time as the oil change. Follow the maintenance schedule in the owner’s manual for interval guidance and oil-capacity notes. Always verify the exact filter and oil requirements for your vehicle’s VIN, as there can be minor revision differences over production runs.
Summary: For a 2020 Subaru Crosstrek, the official oil filter is Subaru part number 15208AA15A. Use VIN-based verification or dealer confirmation for exact fit, and consider aftermarket cross-references from Wix or Bosch that match the same specifications.
