Ok, so i've got this 1.2 Ibiza, i was thinking maybe its a small engine, it'll be low on the MPG, therefore saving me costs, so i noticed i was paying more than i expected on the fuel, so last time i filled up, i put a full tank of Shell V Power, and reset the mileage counter. I just took the car out today, and its already dropped a bar, after only doing 24.3 miles... Now that cant be right surely? (Also, i change gear at around 2500 rpm, and i cruise alot in neutral, you may call me cheap, ill call it recession times...)
