Mitsubishi 4x4 on WMO
A customer stopped by to show off his his Mitsubish diesel Mighty Mite 4x4 converted to run on used motor oil (WMO). The system is very similar to a two tank SVO system... but rather than vegetable oil he's running used motor oil. This is his second vehicle converted to WMO. He has many years of experience running diesels on vegetable oil and various blends of oils and diesel. He says the straight WMO is the cat's pajamas. He also has a VW Dasher running on WMO.

One important change was required. The 4x4 normally has the battery up front in the engine compartment. The 4x2 locates the battery behind the cab behind the removable panel. On this conversion the battery was moved out of the engine compartment to behind the cab here.
