GD, the ONLY reason I got the Dodge was because of the Cummins engine, luckily I've got the 5.9, it's absolutely brilliant. The prepper side of me wants to put in a bio-diesel system for a SHTF situation, that and a locker in the front is my next to do.

what i hear, & one of the reasons i'm looking at the Cummins/Dodge, is because the consensus in the biodiesel community is that this is the best modern diesel truck for biodiesel.

if you buy commercial bio-diesel, you probably won't have to do anything - you are ready.

if you are growing sunflowers or peanuts & plan to press/expel your own oil, i hear a variety of stories about that.

one is that you need a 3 step process to get from sunflower oil to biodiesel -
1. ph correction - Easy.
2. Trans-esterification - not so easy. related to making soap, glycerin, etc.
3. remove the water - Easy. i talked to one guy near Shasta with the Mercedes 300CD, 30 year old car, that only does this step. he puts buckets of oil in the hot sun to remove the water, then pours them in his tank.
(step #0 - filtering).

one thing i have noticed about my own Mercedes diesel is that it doesn't like bio-diesel so much in the winter. well, depending also on where you live.

in a SHTF situation biodiesel is good, but has its limitations. many truckers don't know that their trucks will run on biodiesel. there's not much biodiesel around. when diesel shortages kick in, once the truckers realize they can fuel up with biodiesel, there won't be much - it'll be gone FAST.

except for the fact that some biodiesel stations, you can't pull up there with a big rig.

so, in the summer, i wouldn't worry too much about putting professional biodiesel in your truck, without modifications.

ask these guys, they know. Australian bio-fuels forum.

before you take the big step of pouring pure filtered de-hydrated peanut oil in your truck's gas tank (incidentally, Rudolf Diesel designed the diesel engine to run on Peanut Oil - it has about twice the energy density of Sunflower Oil), i'd talk to someone who has already tried it on a 5.9.

at a bio-diesel conference i went to, almost everybody had the 30 year old Mercedes diesel - modern diesel electronics don't get along with biodiesel. that's the appeal of the Cummins - it does get along, with certain caveats.

at the conference, almost every tech conversation was about how to deal with the gelling up of sunflower oil etc. at cold temperatures. they run 2 tanks, put heaters in their tanks, heaters on their fuel lines, etc.

also, for what it's worth, Taylor Knox, SoCal pro surfer, had one of his sponsors pay for a biodiesel conversion on his truck. might be worth talking to, lives in Carlsbad CA.
