A neighbor has an old MB that he converted to WVO. Apparently not a hard conversion to do, but (according to him) the biggest mistake he sees is people converting their cars to WVO only (without a 'start/shutdown' small dino diesel tank). Cold starting on straight WVO can be difficult (or not possible in some cases).
He does recommend converting to WVO, and is very happy with his 'grease car' MB.
