The 2017 Subaru WRX typically requires a fully synthetic engine oil with a viscosity of 5W-30 that meets API SN or newer, with about 4.5 quarts of oil capacity and an oil-change interval around 7,500 miles under normal driving. Always check your owner's manual or consult a dealer for climate-specific guidance.
Oil Type and Viscosity
In the 2017 WRX, Subaru recommends a fully synthetic engine oil that meets API SN or a higher standard. The most common recommendation is 5W-30 for most climates, though some markets may allow a different viscosity. Verify the exact specification for your region in the owner’s manual or with a Subaru dealer.
Key requirements to follow when selecting oil:
- Synthetic (fully synthetic) oil is preferred.
- Viscosity is typically 5W-30; some markets may specify an alternative like 0W-20—check the manual for your locale.
- Oil must meet API SN or newer (ILSAC GF-5 or newer).
Using oil that meets these specs helps protect the turbocharged engine during high-load operation.
Oil Capacity and Change Interval
Knowing the right oil quantity and how often to change it is essential for long-term reliability.
- Capacity: About 4.5 quarts (4.3 liters) with a filter.
- Change interval: Around every 7,500 miles (12,000 km) under normal driving with synthetic oil; more frequent changes (roughly 3,750 miles/6,000 km) if you drive under severe conditions such as frequent short trips, extreme temperatures, or heavy use.
After changing the oil, reset the maintenance light if your vehicle uses one and verify the oil level with the dipstick.
Practical Tips and Common Pitfalls
These practical notes help ensure you stay within Subaru’s recommendations and keep the WRX running smoothly.
- Choose a reputable synthetic oil that meets API SN or newer and a quality oil filter that matches OEM specifications.
- Avoid conventional or low-grade oils in a turbocharged engine; synthetic oil offers better protection at high temperatures and boost pressures.
- Adhere to the service schedule in the owner's manual and keep documentation of oil changes for resale and maintenance tracking.
Regularly check oil level and appearance, especially after high-performance driving or long road trips, to catch leaks or consumption early.
Climate and Driving Considerations
Climate and driving style influence the ideal oil choice and service interval. In very hot climates, extreme cold starts, or frequent track use, you may adjust the interval or consider a different viscosity per the manual. Always defer to the owner’s manual or your local Subaru dealership for guidance tailored to your region and usage.
Summary
For a 2017 Subaru WRX, the standard recommendation is synthetic engine oil with a viscosity around 5W-30, meeting API SN or newer, with an oil capacity of about 4.5 quarts. A typical oil-change interval is about 7,500 miles under normal driving, with shorter intervals in severe conditions. Always confirm exact specifications in the owner’s manual and use a quality oil filter to maintain engine protection, especially under turbocharged operation.
