dual fuel
i think most of the conversion kits if not all allow for dual use, especially that in some places lpg is not readilly available. here in the philippines its like that any way. it will cost around 450 dollars. do you have any feedback on how it affects our engines, is any good and what about the longterm effects and milage. thanks

My grandfather ran a LP plant for most of his life in the 70's, so hear goes..
LP, or CNG, runs great in the engine, doesn't have all the carbon to mess with the oil, He had the oil tested every 3,000 for the first few years, but eventually just settled on every 10,000.
Yes the horse power is lower, so you have to balance mileage to dollar per gallon. You've also got to know a little about gas vs. LP. With the old cabs, you had to shut off the gas and let the bowl run dry before turning on the LP. While it was dual fuel, it definately was NOT at the same time. With fuel injection it is virtually a flip of a switch to shut off the injectors and turn on the LP.
Unfortunately it's not that simple. On the first fuel injection systems they thought they could just shut off the gas and turn on the LP. But then the injectors were firing dry... NOT GOOD ! A good vehicle system will not be cheap as it has to talk to your PCM to shut off the injectors as well as the fuel when it turns on the LP
Also, you will ALWAYS be starting on gas. It's something about the engine temp that makes it VERY difficult to start on LP.
Hope this helps, It's a fairly easy mod on a carb vehicle, just an adapter plate either above or below the carb. But the injector stuff was still getting started when I got away from it.
PS. Works GREAT for my generator hooked to the natural gas line!

Here is another source I found online. Could a dual fuel truck that could run on unleaded and LPG make having a truck more economical?

LPG Prius Concept Car
Clean@auto reports from Monaco that the French Propane and Butane Federation (CFBP) and the World LP Gas Association (WLPGA) are showcasing a Prius hybrid modified to burn Liquefied Petroleum Gas (LPG) in its engine.
RM Gaz worked with the CFBP and the French Petroleum Institute (IFP) in building the Prius LPG-electric hybrid. The car delivers comparable range to the conventional hybrid, but with fewer emissions.
After all factors are considered, LPG use consumes about 5% more fuel for equivalent performance to gasoline (but it costs less).
In general, LPG yields about 50% less carbon monoxide, 40% less hydrocarbons, 35% less nitrogen oxides (NOx) and 50% less ozone forming potential compared to gasoline. The Toyota Prius LPG prototype emits only 92 g/km of CO2—11.5% less than the gasoline version.
LPG is the generic name for mixtures of propane and butane gases. The chemical composition of LP Gas can vary. Autogas—automotive LPG—generally ranges from a 30% to 99% propane mix. According to Shell, for example, in the UK autogas is predominantly propane, but the rest of Europe more commonly uses a mixture of butane and propane.
LPG is derived from crude oil refining or from natural gas or oil production. Currently, more than 60% of global LP Gas supply comes from natural gas processing plants, but the share varies substantially among regions and countries. In the US, the figure is closer to 70%. With both processes, LP Gas must be separated out from the oil product or natural gas streams.
