I've used these on my Subaru cars for years with never ever any problems. -
http://www.quickoildrainvalve.com/. I really would like to use one on the smart I have coming.
However, I need the help of current new smart owners. Does the oil drain reside at the side of the oil pan or on the bottom? Does anyone know the mm of the oil plug threads? Mitsubishi runs 14mm and MB runs 14mm too. So, I may have the answer to the mm question, unless the smart has something altogether different.
Also there is an adapter if the plug area has a recessed drain plug port. I think also there could be, possibly, a problem if the drain is at the bottom of the oil pan and not the side.
So, can you current owners help me to see if this is worth considering?
Many thanks to one and all.
