Hello all, just joining in. I have been a biodiesel advocate for some time, driving on b100 for 3 years. I have a Passat TDI and just recently bought my wife a MB GL-320 CDI with all the new emmisions stuff that drives great on bio-d as well as the old passat tdi. My first truck was an '82 6.2L Chevy Blazer diesel; I wish I still had that truck! Strongly considering a 2007 DMAX if I can ever find one to look at!
