I worked as a mechanic for Canadian Linen Supply in the early 90's and their entire fleet was LPG. Done right, the conversions are all awesome.
- You're no longer burning a solvent that thins the oil on the cylinder walls.
- You're no longer burning something that condenses on the walls of the combustion chamber or generate particulate.
- Very few additives work well in CNG or LPG fuels, meaning the fuel is less likely to be diluted with stuff like MTBE.
- Gaseous fuels are much harder to compression-ignite, so their effective octane rating is around 100.
- You can advance the timing much, much further because of the above.
- There is almost no difference between the emissions of a hot or cold engine on LPG.
Sadly, in Canada they now sin-tax LPG and CNG to the point that it's the same price as gasoline. You still get the engine life benefits, but that's generally not enough to cover the cost of the conversion.
I'd love to get a LPG set-up for my Tundra.
