I drive a WRX STI and it demands the 98 octane stuff. I run it till just before the fuel light comes on (never get it to empty as it can cause damage) and it costs me around $65 to fill up. That gets me around 360-380km. DH gets less mileage out of it as he drives it fast enough for the turbo to kick in whereas I apparently drive like a Nanna. LOL
