Is half-filling better than a full one for your fuel tank?

In the case of pumping a half-tank of fuel versus a full one, this decrease in fuel consumption is very minor! In fact, if extra trips to petrol kiosks are required, it might even end up costing you more time and money.

It is also recommended to keep your gasoline level above 20%, to achieve sufficient lubrication and a cooling effect on the fuel pump.
