Bio diesel in CRD

Is anyone running homemade bio-diesel in their Liberty? Just curious, thinking about buying one and manufacturing own fuel. In lieu of rising fuel prices.

I recently red about bio-diesel as well and find it interesting. I hope someone responds. Sorry to be an old lady with grammar, but that last part isn't a sentence, and I think you used "in lieu of" incorrectly.

A few of us went together and bought a FuelMeister. I run Bio-Diesel we brew about 75% of the time. It is basically B-100. When I do not run our home brew I can purchase B-95 about 10 miles from my home. On rare occasions I do have to put petroleum diesel in it and I have had no problems what so ever. It really runs very clean with NO SMOKE on the B-100 / B-95. I have about 13,000 miles on my sport. I did run about 80 hours (say 5600 miles) on B-100/B-95 and the engine oil was very clean.

Currently we are not recommending conversion of newer "common rail" or "unit injector" equipped vehicles.

As far as I know, I'm the only person to own a flame red liberty with the light bar, and until someone disproves that to me, I'm going to enjoy it.

I'm running Dieselsecret formula in my CRD and getting 23/mpg around town. I run 60 petro/40 Bio and no problems after 1100+ miles.

I am not running homebrew biodiesel in my CRD, but I am a chemist, and have made it and run it in a Jetta TDI without incident. I am currently buying commercially made biodiesel, although I'll probably build an appleseed processor at some point.

I added enough of the commercial biodiesel to the tank of the CRD to bring things up to a 50/50 blend with the 40 cetane crap the dealer put in it, and I can tell you that it made a huge improvement in the sound of the engine. Not to mention it's exhaust smell!

I'm kinda cautious of my rides, and plan to not take the CRD over about 50% for a while, to let everybody else determine if the higher injector pressures in that common rail system play well with biodiesel before attempting to run 100%, like I do in the Jetta.

But then winter is coming on, so I'll probably be running 50% in both during cold weather. Ask me again in the spring . . . .

Grammar? How about spelling? Did you mean 'read?'

Your CRD came delivered with B5. DCX has tested B20. Anything more than that, don't tell your dealer - cause they'll probably take a dump on your warranty.

And make sure you don't tell them about that little home-made biodiesel operation, 'cause that will give them cause to drop the warranty no matter what the concentration
