Now I know there is a wealth of information in here so I will ask. A young man I know is in the Service and mentioned that his outfit was getting some new equipment with motors that were desigined to run on any type of flamable fluid that they could put in the tank. He said that the testing was going to be over the next several months and run through the desert, in the deep south and as far north as they could go for the cold weather tests. So what Im asking is this,, is such a motor really a viable thing? Could you use old used motor oil, trannie fluid gear lube,thined out of course, diesel or gasoline? Has anyone ever heard of such a thing before or was this young joker pulling an old mans leg???
