Do you fill your car to the brim?

It really depends on how much i can afford to put into the car in the first place lol. although, if i had the choice i would probably always fill the tank up to the brim to save me stopping for fuel all the time

If I am forced to buy petrol locally due to the tank being very low then I will purchase the bare minimum. I always try to wait until I go into the bigger town 40 kilometres away and fill to the brim up there as petrol is roughly 20 cents a litre cheaper, I don't drive up specially for the petrol but I always fill up when there and hope it lasts until the next trip.

It is more cost efficient to fill the tank until the pump stops automatically. Once it does this, do not attempt to add more as this is considered "topping off" and dangerous for the vehicle.

well, i got a cng tank in my car so i don't much care about the petrol but yes i do fill my cng tank full to the brim so that i don't have to come again and again to fill in the gas. petrol, i don't use it much because cng is much cheaper than petrol.
