As far as I know all diesel fuel is biodiesel anymore
Bio-diesel
Honestly it don't matter cause you're using DEF now days if you're caught using off-road diesel (red) it carries a very heavy penalty. ... most of the time you can add transmission fluid to the diesel and it's like a cleaning agent on the valves and pistons
Most diesel does contain up to 5% bio diesel but advertised bio diesel is a whole different animal. Its all going to depend on your preference and your trucks preference on if you would do better going with the higher lvl of bio
Bio. Not sure if it's 5%, or the up to 20% version
Pretty sure its bio diesel.
