This is a great site to track your fuel consumption or track multiple cars.

Basicly you sign up, put in your details since your last fill and it will calculate your L/100Km or MPG, total cost and litres. As you keep filling up and entering your details it will keep track and show your average fuel consumption etc.

I know the lancer comes with one but this is meant for long term tracking.

It can be updated from you iphone as well.

thats cool , have you tracked yours yet? i have never even bothered to track mine just fill up when i need to , im kinda curious now how the car will do

 

I've tracked every fill up since I bought my car, I keep the receipts and write the km, then input the info onto my iphone. Maybe I will transfer info over here.

 

I just started. I will be updating when i fuel up again.
