What year F250's? - I would not run tranny fluid in anything newer than 2004... Especially if he is running used tranny fluid -- Then again, he is a mechanic so if it throws an injector or breaks something he already has the tools and knowledge to change it.
Other than my older vehicle running B99, only thing I noticed was that the entire fuel delivery system was cleaner. Power was down slightly, fuel milage was down slightly, and the exhaust was cleaner. If you run B99 after years and a ton of miles of running the regular stuff, but ready to change your fuel filter soon. On ours trucks at least check it as they could be pretty nasty from the BIO cleaning the system out. Granted today's diesel is a WHOLE lot cleaner than the previous low sulfur diesel blends were.
B20 - I don't notice a power or fuel mileage difference. Everything I have run only B20 on, was never old enough to notice anything else.
I do like having some B99 to have around as it makes a great part and tool cleaner. And is not nearly as expensive, or as toxic as anything else out there. It also seems to work a little better to boot. Problem lately is that all the bio diesel retailers around me have closed...
