Can 2010 wrx use e85

Yes, a 2010 Subaru WRX can use E85 fuel, but it may require some modifications to run efficiently on it. E85 is a high-ethanol blend that can provide increased performance, but the stock fuel system and engine tuning may not be optimized for it. It's recommended to upgrade components like the fuel pump and injectors and to have a proper tune to ensure the engine runs safely and effectively on E85. Always check with a professional before making the switch.
