The oil filling station for lubrication oil includes a conveyor(1) transporting a pallet(1a) with an engine(1b), a support frame(2) mounting a pull-back filler gun(2a), an oil flow meter(3) placed adjacent to the support frame, and a system(4) for maintaining oil viscosity in cold weather. The viscosity maintaining system placed between a main oil tank and the oil flow meter(3) comprises a heating unit(4a) and an oil circulation unit(4b), so as to prevent oil viscosity from being increased due to the cold weather and then to save the fill-up time of gear oil.
