New STI Owner in Impreza, Crosstrek and XV Posted February 24, 2020 Hi Everyone, (posted this in the wrong section before, how do i delete?) First time Subaru owner here, have just purchased a 2007 WRX STI, I am just wondering what fuel i should use at the pump? I have read on forums you can get your car tuned to use 100 octane? Also any recommendations to improve power slightly but improve reliability also? Any advice would be greatly appreciated. -Lucas
