    Will it damage the fuel system or engine?

    Many people are using biodiesel in all types of diesel engines, including the little Cummins in our trucks. You should be able to run it, but check with Cummins.

    im sure it would be ok... i wouldnt think they would sell it if it would hurt the motors (and i would think that the cummins would take that fuel better then either the powerstroke or the dmax). but still check w/ cummins to be safe.

    Check your owners manual. Mine says not to use more than 5% biodiesel. I've read on other forums that the bio has a higher water content and the water seperator cant keep up or something like that.

    I'll try to not type so fast next time, yes I ment Cummins. BTW my brother in law is running 50% bio diesel in his ford and not having any trouble "yet" key word but his is a 96 so we will see what happens later.

    Here's a little more reading on the subject that has been bantering around on the TDR site about what B100 does to injectors. Rember this is probably veggie oil and probably has some home brew processing problems. Notice I said probably :stir: .

    I've been using B20 off and on for a few years now. It seems to make the engine run quiter but nothing else changes like mileage or power. Also made from soy bean. Anyway, I think I'd wait for someone else to test out the 100% stuff over the long haul.

    Thank you for the information I will let my brother in law know about this as well he may not want to run bio in his truck much longer or at least at a small amount.

    I guess you could call straight vegetable oil 'B100'. There's no problem using SVO in a diesel engine, except that it has very poor 'flowability' and needs to be heated so it doesn't gum up injectors, fuel filters and other stuff. There is a company that builds heated tanks of different sizes that can be installed in the truck bed.

    The procedure is to start the truck on regular diesel then switch to the SVO tank when it and the engine warm up, then switch back before you turn the engine off to purge the SVO. You do NOT want to leave the SVO in the motor overnight.

    If you're hauling for a living, that is definitely the system to have. Compute the savings of using less than a gallon of diesel fuel a day over a week, a month and a year. The systems are not cheap, ranging from $2000-$4500, but they will pay for themselves very quickly.

    I've run 20% bio diesel in my 2004 cummins, no problems actually ran smoother and quieter. Draw back price is same as fossil diesel.
