caltex said:Tom, I think the referral to biodiesel was to the diesel fuel made from vegtable oil.
Tom said:I haven't seen "premium diesel", but maybe someone will correct me. Here in the west we see only diesel #2. I believe diesel #1 is used only in very cold climates.
Biodiesel (or biocide) prevents the growth of bacteria in diesel fuel. Folks normally use it only when their RV will sit in storage for long periods of time. If you're driving it every day and frequently replacing the fuel in the tank, biodiesel should not be requires.
Did I misunderstand the question?
