How you add oil/water to engine?

Doesn't matter which way canister is or are lids open or closed, fluids just don't go in.

i only open the lid of the engine/radiator/fuel tank and when i grab the canister, it will be in a pouring position, you just have to adjust the position. Once you see that the canister is fixed with the lid itself and you see the quantity that you have to pour/what is left in the reservoir/tank, you just left click with the mouse.
