The way it was explained to me was as follows: Tank truck goes to local terminal to be filled up. Depending on what brand of station will dictate which and how much additives are put in along with the straight diesel. A driver explained to me that on a recent run he put in 90 gallons of additives to the straight diesel. Now, I'm unsure if the straight diesel already had the 5% biodiesel content or not. I recall he said that the diesel part was 900 gallons but 1) that sounds like way less than tanker truck holds and 2) 90 gallons of additive sounds like a lot for 900 gallons of base stock (9.09%=90/990).
Thomv, the short answer in the difference between branded and non branded is additives.
