Is there a way to figure propane mileage based off of what the gas mileage was before the conversion? Haven't done it yet, but was wanting to figure it out before I did it. 1987 suburban with 350 auto and 35" tires. Currently the mileage is around 12-14 mpg

Haven't done it yet, but was wanting to figure it out before I did it. 1987 suburban with 350 auto and 35" tires. Currently the mileage is around 12-14 mpg Have never converted a 350 auto suburban so I can't speak for it directly. The conversion for a 2001 Subaru Forester will get 21-24 mpg depending on driving habits. As powered by gasoline, it was 23-26. In this area it is ~25 percent less per gallon than gasoline, and ~40 percent less than diesel.

the ford falcon v6 naturally aspirated (mid size saloon) that my housemate drives is petrol/lpg and after doing some calculations it works out she gets approximately 70% distance from a litre of lpg than she would from petrol, but as lpg is half the price of petrol and almost 1/3 the price of diesel it is more than worth it.
she also gets about 70% of the power too but she is not a rev head so she doesnt care about that
this is from an origional dealer fitted system not aftermarket with an 80 litre lpg tank

Ford Falcons.. ) falcons are still made here, in fact all ford mid size saloon cars are called falcons, they just change the 2 letter code to designate the year, kates is 9 years old and is a falcon AE.

Natural aspiration is why she's not getting the full potential for the LPG. If it were fuel injection, it would boost the mileage considerably. For those that don't know what the Australian version of a falcon looks like, here it is: falconThat's the new model. Ford is retiring it though.

sorry, when i say naturally aspirated i mean it has no foced air system i.e. it has no turbo or supercharger
it is fuel injected, i doubt you could find a car under 20 years old that isnt fuel injected here in aus

I would suggest having the engine checked as it should be getting better mileage than that being fuel injected.

Actually that's not true. It's the same as Garret said. No turbo or supercharger.

Naturally aspirated means a carb here. Actually that's not true. It's the same as Garret said. No turbo or supercharger. Actually no it's not untrue, but I have dated myself. A naturally aspirated engine is an internal combustion engine, in which fuel intake depends solely on atmospheric pressure. In these parts, fuel injection is known as EFI or simply fuel injection. Naturally aspirated fuel injection is fuel injection that relies on the vacuum created by the piston in the down stroke with the intake valve open. Any form of air compression, or other external means of forcing a fuel air mixture into the cylinder of an internal combustion engine is 'not' considered naturally aspirated. In short it is not untrue, but it is dated.
