Propane

[matt1030]

I have the Bully Dog Propane system and i've got a couple questions. I'm about to drive 2400 miles does it really help with mileage that much? Is it worth putting in or not?

Does anybody have the system or something similar?

dont know , need to add the cost of them both up and figure it out . herd you need to watch the egt's though .

I've been wondering about this myself. Propane costs about 2.36 a gallon vs diesel at 3.39. How much diesel does the propane system save?

I've heard you can get it at a big savings if you so its for alt fuel. Anyone else heard of that?

I have heard that you may get around a 5mpg increase or so. Probably depends on the system and what not. Also heard that the propane last quite a long time since your only using a very small amount to aid in complete combustion of the diesel fuel, as long as your not using it to pull the sled 300 feet or so. hehe. I think it's a plus, in my book at least. I, however, would not use a 2400 mile trip to test out a brand newly installed. Just my opinion. I hope you have great luck with it. Put it in and let us know how it does for you.

I heard it increases cylinder pressure which could possibly stretch head stud or blow a gasket.Might want to get studded.

not that many of you are Banks fans, however their website has a rather decent explaination... in short: when considering MPG, it may get better mileage, however if you are spending $3 for diesel and $2.36 for Propane, the cost outweighs the MPG. I have looked into propane and wather/meth, decided not to go with it cause it costs more per mile, even though you get better MPG...

Diesel world dec. 2007 issue - "propane injection real world tested"
"Any promise of great savings in fuel costs are probably hollow, unless LP can be sourced well below 65% of the price of #2 diesel.
same issue- shows dyno sheet for 2003 6.0 with 76 horse gain and 177 torque increase
"Well suited for towing"

There is a great write up in last months diesel world or diesel power magazine, I can't remember which. It explained the pro's and con's real well. It also had a dollar figure where propane would have to be as far as being cheaper than diesel fuel to make it worth your while. IIRC propane has to be at least $1.50 cheaper to make it a wash and if the margin is greater thats when you're starting to save $$$. But don't quote me these numbers, they're off the top of my head. Read the article if you can.
