dscott: on my 2007.5 it says in the manual NOT to use any form of Biodiesel whatsoever or it could damage your engine and void your warranty. It says :Use only D-2 Ultra Low Sulfur Fuel(ULSF) or, in very cold temperatures, use seasonally adjusted D-2 (ULSF) or D-1 (ULSF) in the DPF-equipped Duramax diesel. I have the LMM also and unless you have put the Bio-Diesel conversion kit on it then I would only use what is reccommended. Also you can only use an engine oil which is API or American Petroleum Institute classification of CJ-4. This oil has been designed to operate properly with you DPF-equipped Duramax.
