It certainly is! I was trying to keep my explanation...reasonable.
Of course, OTOH, if I had an old VW diesel that didn't cost me anything and I didn't care about, I'd probably go gung-ho on the propane idea. My kubota was a sweet deal...and it's both worth a lot more on paper as well as to me personally than I paid for it. So I'm not about to start wild experiments with it.
Not read a lot about VW's running propane. Truck engines, yes. Guys trying to boost their power and or run a cheaper fuel. VWs and smaller? Can't find many examples of it. Might be a reason?
On the subject of steam engines...from Wikipedia: "In practice, a steam engine exhausting the steam to atmosphere will typically have an efficiency (including the boiler) in the range of 1-10%, but with the addition of a condenser and multiple expansion, and high steam pressure/temperature, it may be greatly improved, historically into the regime of 10-20%, and very rarely slightly higher."
