we have 4 service trucks that run on it, 2 bulk trucks, and my 2500 and my dads 150. along with some random shop trucks that we use to use but not anymore.

right now the kits we use are ones from TechnoCarb. really nice kits easy to caibrate and to install. there also Bi fuel so you dont have to worrie about getting stranded. i just got out of the garage working on converting one of out new 09 350s we got.

Bacicaly your system looks just like ours ill attach some images. But you can buy tanks that mount under the car in the same location as the old gas tank. we use larger tanks (mines got a 250 gallon take).

oh and theres not really and average automotive price i dont think. every month when i get the propane magazines there always flipping **** over installing the first strand of propane fill stations at regular gas stations. Also propane is mainly built for fleet vehicals in the US but chevy and ford both offer stock propane engines with warranties and everything.

Isn't it extremely easy to convert carbureted cars to propane? Voodoo, is there a difference in fuel economy running propane versus gasoline?

nope its all the same. i get the same MPG running propane as gasoline. There are a few things that are problem though. The vapor systems really need gas to run affectivly at idol and start up you will get a terrible idol when the engine is cold and running propane. so i have my kits tuned to throw in gas at idol and start up when its below a certain temperature. BUT GM and Ford have made liquid injection systems that they keep really close to there chest about the tuning and the hardware but there extremely efficient and they dont have any of the previously mentioned problems.

Only problem is the factory addon for a Ford F-150 Propane Roushe truck is like 4500$ and theres a 2 year waiting list.

When I was in the Air Force the fleet on my base was mostly LPG. The city of DC runs a lot of their buses on LPG and so does NOVA.

I've had two propane trucks. Its been a few years (mid 80's) but really no big deal (for carb fitted engines). No difference in operation is apparant when driving, maybe less ping. Kits used to be pretty cheap, maybe 2500 new but there were used around that were less than half of that. Both of mine were california vehicles but back then smog inspections were a joke. I pretty much just used it as my secondary fuel, and swithced off of gasoline when I got out on the highway. The local LP dealer had a service card type machine, so I could come in and fill up at any hour, I don't think there was a road tax back then. LP prices started rising tho and made it less attractive....Bruce

One of dark sides of propane propulsion (that nobody talks about)

And the reason why my porsche project got delayed...

Project BMW aka my daily commuter rebuild:

before:









This valve allso killed cylinder and piston #3



New valves

New vs used head





New used block

New clutch set and OE BMW piston rings (I returned goetze rings)

Ring comparison Left=Goetze Right=OE BMW (Size does matter - Goetze sucks)

New Brakes





After:

niiiiice..love the 5 series look..is more atractive then the new ones. in Roumania lpg is around 50 euro cents ..and regular gas is around 1.20 euro per litre so is good for those times . i`ve seen a 944 on lpg so it is possible.

I had an 80's Dodge van with a 318 motor running on propane. Performance was good and it runs really clean abeit a tad lean. Biggest problem is finding a filling station when you need it. Best to use it in the city where stations are convenient. A lot of cabs use propane power on the crown vics.

every new gas station has a propane pump nowdays, and propane is arround 60% of regular gas price.
Perhaps in Slovenia. In most EU countries LPG is quite difficult to get. Only in southern EU countries it is more common, like in newer eastern EU countries as well. Here in Finland it's a different story. Here in capital Helsinki area are just one or two stations which sell LPG. And those stations are so called "cold stations" where is not service available or any personell present. These stations sell just LPG. Finland is one of the biggest EU countries by size and we have only handful of LPG stations. New "bio" fuels like E95, E10 etc.etc are available from almost every gas (you americans call it gas we call it bensin) station.

Towing that gas tank around seems inefficient to me. I bet you only have to fill up every other month or so though.

I don't think so.

I've traveled across europe on lpg more than once and countries with abundant number of LPG stations include Italy, Germany, Poland, United Kingdom, Netherlands, Croatia, Slovenia, and I am sure there is more on that list.

Than there is a price advantage. This picture is from Netherlands:



It is almost 3 times cheaper in Netherlands than regular gas.

In USD that is $2.18/Liter of gasoline VS $0.76/Liter of Liquefied petroleum gas.


I don't use it for last 50.000km, since I installed new engine, but I will start using it again, as soon as I get seperate electronic valve lubrication system for every cylinder and new injectors installed.
