Interesting. Not second-guessing you, of course -- But most, if not all, carriers I drove for instructed me to never fuel with bio. I drove for this one crazy old coot that forbid fueling in MN in winter, not sure what the h-e-double-hockey-sticks THAT was about.
My understanding through commercials for bio is that it is largely made from algae, something I understand to have been a big problem with marine diesels, and I have heard some trucks running it full-time have experienced fuel system problems. Of course, in regard to the biodiesel, last time I drove commercially was late 2017, so perhaps things have changed?
I'm thinking per your statement that perhaps it hinges on the percentage of bio. I've seen B20 on some pumps, which I understand some setups are not equipped to deal with. I got yelled at once for trying to fuel B20 in Michigan. Maybe that's the rub... *shrugs*
