2003 6.0 PSD - what mods do I need?

OK now that fuel has gone up again. I am getting more and more interested in the whole biodeisel thing. So I have a few questions before I get going.

1) What changes do I need to make to my truck/fuel system to run biodiesel. I was hoping to get the kit from freedomfuelamerica.com and want to run it at 100%

2) Is it better to run it by itself or mix it at like 50/50%?

3) My truck just turned 100,000 so warrenty isn't an issue but milage is. So should I do anything else to my motor before running this.

Any help would be greatly appreicated.

I live in So Cal so temps aren't much of an issue.

You don't need to do any mods to the truck to run bio. Mods come in when people want to run wvo or svo. You can run the bio at any concentration you want. Some trucks react differently to each amount so just play with it and find a good balance for your truck.

What you will need is a few fuel filter changes within a couple months. The bio will clean your fuel tank and send all the dirt to the filters especially since you have 100k miles on the truck you will get dirty filters fast.

I would always have a spare fuel filter on board and tools. You never know when the Bio is cleaning out all the diesel sludge and clogging up your fuel filter.

I have to agree You will need to change your fuel filters after running BioDiesel.
You may get a full tank or two run threw your system with out a problem but then the filter will clog and you will see a decrease in power. No Big Deal just change the filter and be on your way. BioDiesel Fuel is much better for your engine as well as your wallet. Have you looked at www.MIYBioDiesel.com ?
Best of luck

As others have correctly stated you can run pretty much any Bio % you want, but only B5 is "approved" by the engine manufacturer. This is mostly because no BioDiesel standards have been agreed to for other blends.

Biodiesel is VERY high in Cetane, but slightly lower in energy content. It is a very slight net benefit to fuel economy, and a HUGE benefit to start-ability and lubricity.

NOx emissions are significantly reduced with high biodiesel blended fuels, but all other emissions are reduced significantly, if not eliminated completely (PM).

You should have no problems with B100 in SoCal, but as others have discussed, fuel filtration is a BIGGY!
