I just know that running the 6.0 out of fuel is not a good thing and can cause injector problems. Im am guessing that a clogged fuel filter can have the same effect.
Thank you, that does make sense. I am an HVAC tech, so I have to understand how things work in order to figure out problems. I work on old motorcycles alot and they are easy because they are simple. These engines are way more complicated than old Rudolph Diesel ever imagined. My dealer's service manager just says "it's broken" or says i used biodiesel and hands me a big bill.
Thanks, Vince
I got some bad fuel with water and had major problems.
Changed filters twice and drained the HFCM many time within the next 200 miles and was just about to drop the tank when i found the drain on the filter housing under the hood. That made a big difference.
Matt at LIPD and a few other member here told me to run double dose of Diesel kleen for a tank or two.
1/2 tank and all is well.
My point, a little water and trash in the wrong place can cause problems .
Make sure that they DRAIN the UPPER filter housing.
Most diesel in N.IL, if not the whole of Illinois, is 11% biodiesel. The state tax benefits make use of over 10% bio conducive. I don't know for exactly how long this has been true, but for at least the last year or so. I found out that Biodiesel.org doesn't list all who use bio because it's not mandatory to disclose it.
Road Rangers had a bad run of bio a couple years ago that caused quite a few customers to have fuel related problems, and I had a minor problem with my VW TDI after refueling at Mobil at about the same time (hard staring), but I'm not sure my problem was bio related. The bio didn't meet ASTM standards and the problem was corrected.
Kelley-Williamson, local distributor in N. IL of Mobil fuel, told me that they (and their competitors) are continuing to use 11% bio throughout the winter along with proper winter blending as usual. I believe that the bio that is currently commercially produced is in strict accordance with the ASTM standard that applies and is no more prone to causing fuel system problems than the dino diesel it's blended with. I don't believe that the biodiesel was your problem. Possibly, it was a fuel problem in general. As previously stated, a plugged fuel filter could have caused the injector demise you experienced.
