The 2018 Crosstrek uses 0W-20 full synthetic engine oil. This grade is Subaru's standard recommendation for the model year, designed to deliver optimal cold-start protection, engine longevity, and fuel efficiency.
To keep the Crosstrek running smoothly, it's important to use oil that meets this specification and follow the maintenance schedule outlined in the owner's manual. The following guide summarizes the key requirements and practical tips for selecting and maintaining the correct oil.
Oil type and viscosity
The 2018 Crosstrek specifies 0W-20 synthetic oil as the standard specification. This viscosity helps ensure reliable lubrication at startup and consistent protection across typical driving conditions, including colder climates.
Regional considerations and warranty notes
While 0W-20 is the common recommendation, some markets or driving conditions may require or tolerate regional variations. Always verify with your local Subaru dealer or the owner's manual for any region-specific guidance and warranty considerations.
Key points to remember before you buy oil:
- Oil grade: 0W-20 full synthetic
- Oil specification: API SN or newer
- Compatible with most climates; verify any regional notes in the manual
Using a high-quality synthetic 0W-20 that meets API SN or newer is the standard approach. For exact requirements relevant to your vehicle, consult the owner's manual or Subaru's official resources for your country.
Maintenance and practical tips
In addition to selecting the right oil, following the proper maintenance steps ensures engine protection and warranty compliance. The Crosstrek's oil and filter should be changed according to the schedule in the owner's manual, with a preference for synthetic oil if you drive under normal or severe conditions.
To help you navigate the process, consider the following guidelines before you travel to the service bay:
- Choose a synthetic 0W-20 oil that meets API SN or newer; prefer Subaru or OEM-approved brands when possible
- Verify the service interval and reset maintenance reminders after a change
- Have the oil filter replaced with an appropriate Subaru-compatible filter to ensure proper filtration and fit
Following these steps helps ensure the Crosstrek's oil system performs reliably and the engine stays protected between services.
Summary
Bottom line: The 2018 Subaru Crosstrek takes 0W-20 full synthetic engine oil, meeting API SN or newer. Use a high-quality synthetic 0W-20 and adhere to the owner's manual maintenance schedule to maintain engine performance and efficiency.
