What gas does a 22 wrx take?
The 2022 Subaru WRX requires premium unleaded gasoline with an octane rating of 93 or higher to achieve its best performance and engine safety. Regular 87-octane fuel is not recommended for this turbocharged engine.
Fuel type and octane requirements
Premium fuel and octane guidance
The WRX’s turbocharged 2.4-liter engine benefits from higher-octane fuel. Subaru specifies premium unleaded gasoline with an octane rating of 93 or higher for best performance and reliability. If only lower-octane fuel is available, you may experience reduced power and potential engine knock. Always refer to the owner's manual for your market, as local fuel grades can vary.
Key considerations for octane and fuel type:
- Octane rating: Use premium unleaded gasoline, 93 octane or higher, for optimal performance.
- Regular fuel caveat: 87-octane gasoline is not recommended for the turbocharged WRX.
- Region and labeling: Follow your local fuel labeling and the owner's manual for your market.
Using the recommended high-octane fuel ensures the engine operates as designed and maintains maximum performance.
Ethanol content and fuel compatibility
Fuel composition and compatibility
The WRX is designed to tolerate standard gasoline with ethanol content up to 10% (E10) in most regions. Fuels with higher ethanol content (such as E15 or E85) are typically not recommended unless Subaru specifies otherwise for your market. Always verify your area's fuel composition in the owner's manual or with a dealer.
Key ethanol guidelines:
- E10 compatibility: The WRX generally accepts gasoline with up to 10% ethanol.
- Avoid high-ethanol fuels: Do not rely on fuels with E15/E85 unless your region's Subaru guidance explicitly allows it.
- Brand consistency: Use reputable fuels to minimize contaminants and ensure consistent performance.
In practice, most WRX owners can safely fill with standard E10 fuels available at major stations.
Practical fueling tips
Best practices for fueling and maintenance
To maintain performance and reliability, consider the following guidelines when fueling your 2022 WRX:
- Use premium gasoline (93 octane or higher) whenever possible to maximize performance and prevent knock.
- If premium is unavailable, use the highest-octane fuel you can obtain and avoid continuing to drive long distances on low-octane fuel.
- Fuel with up to 10% ethanol (E10) is generally acceptable; check your manual for region-specific guidance.
- Maintain good fuel quality and consider ethanol stabilizers if you store the car for extended periods.
When in doubt, consult your Subaru dealer or the owner's manual to confirm region-specific fuel requirements and warranty considerations.
Summary
The 2022 WRX requires premium unleaded gasoline with an octane rating of 93 or higher, and it is compatible with E10 (gasoline containing up to 10% ethanol) in most markets. Avoid regular 87-octane fuel to prevent knock and loss of performance; consult the owner's manual for any region-specific variations.
