Biodiesel Ram 2500 Grabs the Bullrun by the Horns

bullrun-day1-165Each year, the fastest, loudest, and some might even say craziest enthusiasts come together for the annual Bullrun Rally. This year, running amongst the pack of performance cars is a very different type of raw strength: a 2008 Ram 2500 Diesel. Navigated by Chris Morrow and his friends Blake & Doyle, the 2500 has been converted to run on biodiesel and outfitted with auxiliary tanks to meet the rigorous, long-distance demands of the cross-country trek.


While a behemoth like the 2500 might not seem like a natural fit for the 8-day, time-sensitive run, Morrow and his rig have a unique advantage thanks to the fuel-efficient set-up. According to Morrow, the 2500 can average about 1300 to 1500 miles between fuel-ups, making the race from NYC to Vegas a lot less daunting.


The rally officially kicked off on July 9th, and the guys are committed to documenting their exhilarating journey from start to finish. For a glimpse behind the scenes (and into the cab) of their homegrown operation, check out their blog:

  • Thanks for the plug guys! We’re on Day 6 today heading through Arizona to Hotel Valley Ho in Scottsdale. Our Dodge is running great on G2 biodiesel from 11 Good Energy
    So far with the G2 our 2500 is getting 18-20mpg on that 6.7L Cummins diesel engine! Quite an improvement off the sticker 15-18mpg. Plus the added horsepower with the G2 is helping haul our tanks, guys, and luggage.

    I have removed the exhaust boxes etc on my 2009, 3500 6.7 cummins and I am fitting stacks. Will this be a problem with no boxes? no backpressure

  • You had me fooled.  Now that someone pointed it out, I see how you did it.   It should be important to state this is not some breakthrough in fuel efficiency as it first appears.  A casual observer would think you managed on a normal 16 gallon tank you can find for a Dodge 2500 that you managed to go 1300 miles.  That would be miraculous.   Biodiesel from the looks of this on the surface provides much greater fuel efficiency than it actually does.  Now that I was pointed out to the page where you showed what you actually did with the auxiliary tank, you realize the fuel efficiency is not that much better than regular diesel.   Still given the cost of biodiesel dropping to $1 a gallon, you could at least see significant improvement that way.
