What kind of oil does Subaru Ascent use?
The Subaru Ascent typically uses synthetic 0W-20 motor oil.
To understand this in context, the Ascent’s 2.4-liter turbocharged engine is designed to run on a high-quality synthetic oil that meets current API and ILSAC specifications. Most model years specify 0W-20 as the preferred viscosity, with allowances for different climates and availability. Always refer to your owner’s manual for the exact requirements for your year and region.
Official oil specification for the Ascent
Here are the core oil specifications you should follow for the Ascent’s engine. The list summarizes the standard guidance you’ll find in Subaru’s documentation and owner manuals.
- Oil type: Full synthetic motor oil
- Viscosity: 0W-20 is the recommended grade for most conditions; some markets may permit 5W-30 under specific circumstances or if 0W-20 isn’t available
- Certifications: API SN Plus or newer; ILSAC GF-6 (GF-5 is acceptable for older engines)
- Oil capacity: Approximately 6.9 quarts (with filter) for the 2.4L turbo engine
- Oil filter: Use a genuine Subaru oil filter when servicing
Concluding paragraph: Adhering to these specifications helps protect the turbocharged engine, maintain performance, and preserve warranty coverage. Synthetic oil with the correct viscosity is essential for heat management and longevity.
Maintenance and practical tips
Practical guidance to keep the engine in top condition aligns with Subaru’s maintenance recommendations and general best practices for turbo engines.
- Follow the owner's manual for oil-change intervals, which is typically around every 6,000 miles under normal driving; more frequent changes may be advised under severe driving conditions or heavy use
- Use the correct viscosity (0W-20) and a synthetic oil that meets API SN Plus and GF-6 or newer specifications
- Install a genuine Subaru oil filter and use the recommended oil quantity during service
- Regularly check oil level and monitor for leaks, consumption, or unusual engine noise, especially if the vehicle is frequently towing or operated in extreme heat
Concluding paragraph: Sticking to these maintenance practices supports reliable performance, fuel efficiency, and the longevity of the Ascent’s turbocharged powertrain.
Summary
In brief, Subaru’s Ascent is designed to run on synthetic oil with a typical viscosity of 0W-20, meeting current API GF-6 standards, and requiring about 6.9 quarts per change with a proper Subaru oil filter. Always consult the specific owner’s manual for your model year and region to confirm the exact requirements and any climate-based exceptions.
