When refueling, is it advisable to fill the tank to the very brim or maximum limit?

Question

DentroTest · Accepted Answer

No, it is not advisable. While one might want to maximize range, filling the tank to the very brim (topping off after the nozzle clicks) carries risks. Spillage due to expansion: Fuel expands with heat. If there is no air gap left in the tank, fuel will overflow through the filler neck or vent. Road Safety: Spilled fuel on the asphalt (especially diesel) creates slippery conditions, which is extremely dangerous for motorcyclists and cyclists. Mechanics: In modern cars, overfilling can flood the vapor recovery system (EVAP charcoal canister), leading to expensive repairs. Therefore, the correct answer is no, due to the risk of spillage caused by vehicle movement or thermal expansion.
