I own a 2002 Ford Focus 4 door sedan. It has 129,000km on it and a 50 liter gas tank. It costs me about $50 CAD to fill the tank and out of that full tank I have been averaging 415-450km. I’ve been told by my friends who have much more experience with vehicles that it is absolutely terrible gas mileage.
I had an oil change about a month ago and they said nothing was wrong with the car and it’s in relatively good condition. I’m really stumped as to why it’s so bad. Apparently I should be getting at least 600km per tank.
