Hi again: I filled my 2000 jetta with Biodiesel and it has worked fine. I am ready to also start using it in my 2006 jetta but then I read the post regarding Intro to Biodiesel.... In the article it says that vehicles from 2000-2006 will run fine with B100, but it also says that vehicles from 2006 and up use DPF and that the method of regenerating the filter is with post combustion fuel injection to raise the exhaust pipe temperature. I own a Ford Excursion and it has DPF as well since it is mandatory from that year. So, is it safe to run BioDiesel in my 2006 jetta? I dont want to dilute the engine oil and have the risk of ruining the engine. Any thougths on this?
