Propane

[ttwndoc]

Any body ran propane on 6.4 motor? What is the risk, pro, and cons of it? What system to use? Have an opportunity to put a system on very cheap and want some advice and learn about it. I have 2008 F-350 dually running all the spartan stuff. Thanks

Propane has generally been abandoned by most drivers and the industry as a whole. What are you looking to gain with propane, that cannot be gained by another method?

Propane usually equates to things getting melted, broken, or blown up, none of which are desired.

If ran properly Propane is fine to use but the real reason why not many use it anymore is because the price to make a truck go down the road 1 mile on Propane is almost exact as Diesel. So to go through all the trouble and cost of Propane isn't beneficial. Many corporations still build propane powered generators, forklifts, floor buffers, vacuum cleaners and so on. Most of these items are used indoors where emissions are important.

ive been looking into CNG lately.

what i cant understand is how pre-detonation doesnt occur...

Wait I was talking propane as an additive in a diesel not taking over completely. Same thing with CNG, cost is too high and benefits arent that great.

what is the cost anyway?last i read it was about $1500 for the "Phill" station and $1500ish for the conversion. i havent calculate the payoff at 75% cng or propane.

The reason I am asking is because I have a way to put a system on the truck for around $600 and can buy it for $1.25 a gallon. My Aunt works for propane company here in our town. They have done several had on too several one tons. report a 5-6 MPG increase. I know that the cost is buying 2 fuels. But I was just curious.

Thats pretty similar to the costs that I found a while back here in california.

[ridiculously_necessary]

yeah, the numbers may be out of date. if i ever lose veg sources ill probably do cng. something between $.90 and $1.30 around here iirc. ive heard reputable rumors of guys getting 40 to 65mpg. that would be equivalent to 75% or thereabouts cng mix.

One of the biggest pluses to propane as an additive or fuel supplement is the fact it helps the truck burn more of the fuel in the cylinders. Now in the days of the HEUI it help more cause the system doesn't generate the extreme pressures or multiple injection events of a Common Rail. Basically the common rail engine can burn the fuel that is in the combustion chamber more completely than an older engine. Therefore propane stops becoming an catalyst and starts become a second fuel that IMHO adds unnecessary complication and possible issues w/ not enough ROI on a newer engine.

Maybe on an older truck...but not a CR.
