Actually Cummins just approved the use of B20 in our trucks a few months back. I actually got an e-mail from them. All the other diesel manufactures say 'No' to bio or the highest bio they'll let you run is B5.

Yes Cummins has approved the use of 20% Bio with extra filtering for water. Dodge only allows 5% Bio when it comes to those who have a warranty. Below is from Cummins on Bio fuel.
----------------------------------------------------------------------------------
A maximum blend of 5% biodiesel (B5) is acceptable as long as the biodiesel mixture
meets ASTM specification D-975, D-975 - grade S-15, and ASTM D6751. A biodiesel fuel blend that is higher than 5% is not acceptable without additional fuel processing because these higher percentage biodiesel blends contain excess amounts of moisture which exceed the water stripping capability of the on-engine final fuel filter. Should a higher percentage biodiesel fuels be used an auxiliary water stripping filter will be required.
A maximum blend of 20% biodiesel (B20) can be used by government, military, and
commercial fleets who equip their vehicle(s) with an optional water separator, and adhere
to the guidelines in the Department of Defense specification A-A-59693 (in addition to:
ASTM specification D-975, D-975 - grade S-15 and ASTM D6751)

Yeah but a member on another forum told me that Cummins might allow up to a B20 fuels but Dodge will only allow up to B2 for warranty coverage... Cummins has nothing to do with warranty repairs its solely Dodges problem... So you MUST go with Dodge's guidelines for warranty coverage...
The only reason I know this one I got a few phone calls from guys make there own BIO. B100 of all things and done some fuel system damage and ended up losing his warranty and pay for the repairs... He was told the maximum was B2 allowable by Dodge's Standards...

Is an Airdog water sperator considered a good enough filtration unit to remove the moisture of B20? Reason I ask is cause I did just install an Aidog system on my truck and I know several local fuel stations are only offering Biodiesel now. I just want to make sure IF I end up purchasing Biodiesel that I wont ruin anything.

There really shouldn't be any more water in Biodiesel than there is in petroldiesel. If there is water in the fuel, you need to have a talk with the producer, because he should be drying the fuel better.
We'll wait for Charlie to give us the authoritative answer, but I don't think that the water separator removes water that is "atomized" or whatever they call it into the fuel. It only removes free moisture.
Get a glass of biodiesel if you see the water droplets, that is what will be removed by the water separator, the water you don't see is what is dissolved or atomized into the fuel.
I have never tried this, but I was told that if you take one of your wife's favorite frying pans and pour some bio-diesel in the the pan. Put it on the stove and raise the temparture to over 212degrees... if there is water in biodiesel it will sizzle at the boiling point of water.

The AirDog has no trouble with biodiesel. The wire screen prefilter/water separator catchs the large parrticlates and the Stratapore filter handles the rest. The veggie oil conversion people, Fossil Free Fuels, Grease Car, etc., use our Raptor fuel pumps with their conversions. No problems, just a real good pump!
