The milage has stayed pretty consistent since the engine conversion back in
'94. Lower milage in the winter (no engine air preheat, prob runs rich for
longer for that reason).

I have been very happy with this conversion, wasn't a big job, hasn't been
troublesome at all, not at all worried about repair difficulties!

Parts for the engine seem to be readily available :)

Planning on keeping this van for a lot longer, using it as a daily driver as
well as for trips. If I was worried about resale value, i guess i would have
kept the stock diesel engine, covered it with cosmoline, and parked it in
the barn!
