I just acquired an old MW snow blower and need to change the oil, but I have not idea where the drain plug is. It is a 4HP, Tecumseh from around 1984. The model number label is worn, so I have no idea what it is. I have never changed oil on a snow blower, so I don't even know where to start.
Also, it says to use, 5W-30. Do I use the same kind of oil as I do for a lawnmower, or do I use auto oil??
Any help would be greatly appreciated.
