How can you run b100 in your 2011 6.7 ford powerstroke?

Answer 1

you should be able to run b100 in your 6.7 if you do a DPF delete on your exhaust. The DPF is there to catch particulate (soot) that naturally occurs in diesel engines. That is why these new diesel trucks don't smoke like they used to. As the DPF catches more and more soot, it gets clogged up, choking off your engine. The ECM looks at backpressure sensors in the exhaust to tell when it gets clogged. When it reaches a certain backpressure, the ECM triggers a "regen event". Basically, the ECM fires the fuel injectors in the rear 2 cylinders with the exhaust valves open. The raw fuel travels down the exhaust system through the catalytic converter where it becomes superheated and vaporized. The superheated fuel vapors travel to the DPF, where it incinerated the soot, and turns it into ash, which falls down into the bottom of the DPF case, freeing up the DPF to catch more soot. Unfortunately, because of the high compression ratio of the engine, a certain amount of blow-by occurs, where raw fuel goes down into the engine oil. Because the regen event essentially doubles the fuel usage of 2 of the cylinders, more fuel gets down into the oil, causing what is called fuel dilution of the oil. Biodiesel does not react well to the engine oil when fuel dilution occurs, and causes problems for the engine. So, to be able to run b100, you will need to delete the DPF from your exhaust and use a tuner to turn off the regen events. H+S and Spartan both make good tuners for the 6.7. Just remember that by removing your DPF, you are violating federal law by removing EPA mandated equipment, so you could get in some serious trouble for doing this.
