I see a very consistent ~450KMs per tank from a good mix of inner city (Toronto) and highway commuting (60kms return daily). I've seen over 500KMs with long consistent speed road trips, and even then I could have gotten more but I chose to refill at the next station�
I don't feel I do anything conscience to get ââ?¬Ë?goodââ?¬â?¢ gas mileage either... I use Sunoco 91 or 94 exclusively, run synthetic and change it every 5-7000kms depending on my mood, occasionally I'll put Redline fuel treatment in, stock SVT less K&N and no resonator and I check tire pressure on a regular basisââ?¬Â¦
