If there are two identical cars - one takes regular gas and the second one takes LPG. Gallon per gallon - Will these two cars get identical gas mileage?

The mileage is dependent on the energy of the fuels. Regular gasoline contains far more Btu's than LPG (propane). Propane contains around 2500 BTU per cubic foot of standard gas vs 4000BTU+ for gasoline. Even though the vehicle may burn the exact same number of Btu's for each mile, it gets those Btu's from fewer gallons of gasoline than LPG resulting in a higher miles per gallon rating.
LNG (liquid natural gas, or methane) contains around 1000 BTU per cubic foot. It will take more gallons of LNG to power the same vehicle the same distance as gasoline or even LPG due to it's lower Btu content. LNG is used a lot in urban areas for central bus transit, etc. due to the fact that it has much less emissions than gasoline or diesel. This is due to the hydrocarbon chain being much smaller and easier to combust, which allows it to generally burn more completely and not leave the carbon monoxide and other harmful gasses in the exhaust.

Just to reiterate what rider said really. LPG converted cars don't cost any more to service. Its way better for the environment too, burning with far fewer hydrocarbons and co2 than petrol. However, a badly installed and poorly set up LPG system is next to useless, so if you want to run a gas Jeep or any other car, make sure the system is both installed and set up by a professional. You need the conversion certificated too if you want insurance and inner city toll reimbursements. I run a 4.6 Range Rover with a sequential Iwema system. I am very happy with it. Hope that helps.

Honda has claimed that their Civic LNG (as opposed to propane) will get very similar performance and milage to their gas models. The difference is in the price of fuel.
If you have natural gas running to your house, you can put a compressor on your house that will fuel the car overnight. The price per gallon was almost half what gasoline is today.

Almost duster.
The two cars will get different mileage due to the fact that the LP is already dispersed and the molecules are "more potent" than that of gasoline. This is why busses in major areas use propane or Natural gas to run on. They are cleaner to the atmosphere due to a better burn of fuel...

having run a number of duel fuel cars there isnt much difference!! in theory running on lpg should give slighly less mpg but ive found its not really that noticeable. what is noticeable is 40 per per litre as opposed to 92 per per litre for regular gasoline. it makes a big difference!!

gasoline has to be compressed, before it becomes vapor and liquid propane, the vapor is there and the liquid supports the already present vapor.
Did I Get That Right??
