Full tank indicator
How do we know we have a full 42 liters or 11 gallons of fuel?
Is it at the first click of the pump or is it when we actually see it fill to the brim? I've been filling to the first click but I kinda feel like my mileage calculations might be off. |

First click is the closest to published fuel capacity.
If you fill to first click every time, and properly divide distance traveled by fuel top up amount, there is no way your calculations can be off. The only variable in the equation would be the sensitivity of the shut off on the gas pumps. That is why for truly accurate calculations it is recommended to, as much as possible, use the same station, same pump whenever filling the tank.

CTScott tested the tank on one of his 2nd Gen hatches for absolute capacity and concluded that absolute is 12.8 gallons. Dead on correct in my book...not only because it was CTScott who measured this , but also from my own experience. I once ran out of gas while pulling into a gas station in my 2007 Yaris, and it took 12.777 gallons until I could see 'gas in the neck'. Very logical that from that point up to 'filling it to the brim' would be 0.023 gallons. |

Thanks for the replies.
I've been using Fuel Buddy app to record and calculate fuel efficiency instead of doing it manually. I'll do it manually as well and compare results. I'll also try my best to fill up at the same station and pump. I have heard before that different pumps can have different sensitivity. I'm scared of filling to the brim as once with my VW my fuel tank started leaking right after filling to the brim. Maybe there's no connection but I'm scared. |

BTW, I really only record mileage for purposes of monitoring condition of the vehicle, not for trying to milk every km/liter out of this thing that I possibly can so small errors in calculations don't phase me.
