As for the recommended engine oil, the manual suggests using 0W-20 synthetic oil for optimum engine performance and protection. However, if synthetic oil is unavailable, you can use conventional 5W-30 oil as a temporary solution but should change to 0W-20 synthetic oil at the next oil change.

Regarding the engine low oil level warning indicators, be sure to check the engine oil level when the warning indicator appears and refill with the appropriate engine oil if necessary. If the warning indicator does not turn off after refilling the engine oil, or if it appears even though the engine oil level is within the normal range, have the vehicle checked by a Subaru dealer.

The Subaru WRX with a 2.0L 4-cyl engine (engine code FA20F Turbo) takes 5.4 quarts (with filter) of 5W-30 synthetic oil. A new oil filter and a crush washer are required.

Selecting the Right Engine Oil

In addition to knowing your WRX’s engine oil capacity, choosing the appropriate engine oil for your vehicle is essential. Subaru recommends using synthetic motor oil with a viscosity rating of 5W-30 or 5W-40, depending on the climate in which you drive. Synthetic oil has been proven to provide better lubrication, increased engine efficiency, and longer-lasting protection against wear and tear. Be sure to consult your owner’s manual for the specific oil requirements for your Subaru WRX.

Oil Change Intervals

Regular oil changes are essential to maintaining your Subaru WRX’s engine performance and longevity. Subaru recommends changing the engine oil and oil filter every 6,000 miles (9,656 kilometers) or every six months, whichever comes first.

However, if you frequently drive in harsh conditions or participate in high-performance driving activities, it’s advisable to change the engine oil and filter more often.

Conclusion

Maintaining the proper engine oil capacity is crucial to ensuring that your Subaru WRX performs at its best. By understanding the oil capacity for your specific WRX model, selecting the right engine oil, and adhering to the recommended oil change intervals, you can help protect your engine and extend the life of your vehicle.

Always consult your owner’s manual for the most accurate information and guidance on maintaining your Subaru WRX’s engine oil.
