Thanks for the replies gents. I guess what I want to know is 1 year better than another? Do they all have the same IP? Does one model have more injector or GP issues than another. Do they all have the same head? Information so that I can determine if one handles biodiesel better than another. My 300SDL runs like a champ on Bio and I want to get the wife a newer model if possible.

Thanks again,
A
