Propane:
The good:
#1. Clean burning fuel.
#2. Engine oil pretty much last forever.
#3. Fuel lasts forever over time if not used. (think genset that is only used very seldom.)
#4. Octane value.
The Bad:
#1. Energy density; gas=100% propane=66%. (mileage)
#2. Power output. (Waaaay down on power)
#3. Poor starting in cold weather. (If not impossible)
#4. High cost/energy density.
#5. Heavy tank needed.
#6. Large tank needed.
#7. Hard to find compared to gasoline.
#8. Hard on valves.
#9. Takes a long time to fuel up.
#10. Vehicle cost a lot more if duel fuel.
Pretty easy to see who wins.
