Hattinger Stahlbus GmbH has patented their oil drain, which makes draining automobile oil much easier. Their motto is: “The intelligent way to change you oil!” And it works like this:
“The stahlbus®-oil drain valve takes the place of the conventional drain plug. For the oil change, you unscrew the safety cap and attach the quick connect with the drain tube.
Once this is connected the valve opens and the oil starts flowing into the catch. After disconnecting the drain tube, the valve closes automatically and you only need to install the safety cap.”
An intelligent solution to avoid spills and dirty hands. Made in Germany.
