1) I wonder why they stopped using it in the two strokes?
2) I don't understand the concern about the "coolant" (real or
) getting into where it shouldn't be vs. water. If we were talking gasoline then these two observations would be even obvious to me. Weren’t early engines lubricated with caster bean oil? Of course it would be more difficult to diagnose much do to the lack of damage – too pro?
3) My guess is that water became the industry/world because it's cheap and one of the four fundamental elements found in the 19th century.
3) Does anyone know the thermal transfer characteristics of oil? We do know that it will easily handle much higher temperatures. We also know that in closed heat exchange systems that oil if often used as the conductor - electric heaters.
4) Don't internal combustion engines run more efficiently at temperatures over 212 F? Of course pressurizing and treating the water to help tolerate this unearthly environment is required. Part of my "dream" was a result of seeing so many miracle fuel savers that were simply pre-heaters. Burning your coolant just sounds nice to a guy that lost both a Ford and a Chevy one cold and wintery night when he was sixteen.
