I'm about to pick up a 1st gen cummins in the next week or so and want to run on some form of Bio. So far I'm leaning towards doing a greasle conversion because it seems to be less work and less limited as far as being on road trips. I've heard the veg oil doesn't run quite as clean through the engine as bio. What do you guys think?

I'll say it, and no, I don't hate the planet. Run diesel in it. It's a $6000 motor that was designed to run best on high sulfur fuel. You already can't do that, so why give it more of a challenge.

Just a tidbit...injectors are at least a hundred each and the pump on that thing is most likely $700 - $1000 these days. I wouldn't tempt fate on a motor that costs that much coin to work on.

And before you say it, I can work on one too and it's not the labor that is the issue on those. Besides, you'll have enough issues with the Dodge itself. :)

:stupid:

A friend of mine burned up his injection pump. We had to replace the injection pump and the lift pump. He decided to upgrade to the FASS setup and the truck was awesome after that.

$3000 in parts, about 18 hours in labor, not including beer. I bought a Ford 7.3.

I had a 7.3 with nearly 300k with the original pump. I changed the oil every 25k on it. Most awesome truck ever. It got totaled on the interstate. :rant:

I spent less on it in total, than Ford did on repairs on a 96' Powerstroke.

Had a 6.9 too that was stupid tough. Had 5:something gears in it and would only do 68 mph in a free fall off of a cliff. :rofl: It would pull anything though.

4 cyl TD cummins in a smaller turdango though? i'm in...
will never happen. all 3 US auto makers stopped their small diesel concept work...plus the Durango wont see a new model until 2012 i believe...and possibly might have a name change to the Magnum (hopefully not!)

the only 4cyl diesel truck in the States will be the new Mahindra coming later this year.

Guys, he's talking 1st gen Cummins, 12v, mechanical fuel pump, solid injection pump. This engine is much more reliable than the second gen 24v Cummins (I had one, it wasn't bad but had to keep an eye on the lift pump pressure). I'd never recommend a grease conversion on a 24v truck but on a 12v I say go for it.

anyone else see the irony of the Free education, attack the UC Presidents home, liberal activist protester driving a full size diesel Pickup
Wait till he's in his 40's, then you'll see the real irony. He's going to be a slick, rich republican who's company rapes some third world forest for profit. :p

You owning one doesn't change the cost of a pump or injectors. :think: I knew all too well he was not talking a 24 valve. I still wouldn't recommend it on a 12 valve. Not if I didn't have coin to address systems failing. Seals and ports are what fail on these pumps and they weren't designed initially for anything but high sulphur diesel.

These geniuses think there is a trunk on a truck. I wouldn't go with this plan. :think:

Thanks guys, I'm not trying to blow up my truck here. So no go on the grease? what type work are we talking about to get it working right? I know I need injectors. the truck I'm going to look at tomorrow has a second tank in the bed so I figured I could buy a heater and heat the 2nd tank maybe. What exactly is up with the injector pumps?

Any word on bio diesel. I can get a tank to make it for free but long term i was thinking grease would be better. If grease is a no go though then 50cents a gallon with limited range (talking road trips only) is better than full pop on diesel

Didnt look at the other responces yet, but if you get set up right at home, it runs exactly like deisel fuel. Because its going to be the same.

you het it, you filter it, you chemically seperate, you adjust the specific gravity........ No upgrades needed after that..... initial cost can be a bit, most people get setup to be able to do a hundred plus gallons at a time, but fifty would be a nice amount as well.....

Hey Loco, I just read your posts...... it actually has absolutly nothing to do with Sulfer.... it parafin...Hi slufer is what eats up the seals.....



To truly do this right, you do have to be a bit of a chemist
