i made mistake and put biodiesel in my 2007 cummins dieselit seems pilot truck stops have it in thier pumps they have little sticker on the pump says not to use in 2007 or newer diesels what damage can this cause to the engine in my truck and why did they make to not be able to use biodiesel

Cummins announced last week that you can use B20 in most years, I'll have to look up the start year. Ford says only B5 for the new 6.4L. Had the same problem in Detroit last week with our HD Shootout coming to the website soon. We went to a Pilot station that just switched stickers. Doubt if one tank full will cause damage.
