I've used it before, by accident really. I didn't know it untill I had fiiled one tank, then I noticed a sticker on the pump that said it was between 6 and 10% biodiesel!?! I couldn't tell any difference though.
I've run everything from B5 to B20. Multiple tanks of B20. Even at B20 I couldn't tell the difference. The fewer regens help offset the slightly less MPG you get. Careful if you have a lot of miles with regular diesel - even B20 will clean the tank and the lines out. Possible to clog a fuel filter up and it also gels at a higher temp then regular D2. Treatments will help with that. (I don't worry about it since I am rarely in temps below 40F.)
Now to try and find a Wally World with diesel around me...
I top off my tank with it every once in a while if I'm going past one of the few stations that has. As mentioned it will clean out your fuel system and has good lubricating qualities. I've never noticed any difference in performance or mileage. But sometimes, depending on concentration, I can smell a difference in my exhaust. Especially with my Skid loader or Mini Excavtor that don't have the emission stuff. You get a real pop-corn or french fry kinda of smell.
But it is impossible to find around here after Oct 1st when the winter grade fuel comes out. Station just stop selling until springtime. They don't want their dispensing pumps gel'd up any more than we want our trucks gel'd.

NO Wallyworld's around me sell Diesel, much less B20.
PH - When I had a VW Diesel (pre 2007) I noticed a lot less black soot in the back of the car when I used BioDiesel too. Do you notice that as well, with your non-DPF equipment?
This 'new' post 2007 ULSD fuel smells a WHOLE lot better than the old high sulfur stuff. Biodiesel makes it even better. Not that I recommend using it as cologne/perfume... At least I can wash my hands and the smell disppears, unlike if I got a drop on my before you went the rest of the day smelling like an oil refinery.
My mechanic (22 yr Ford Tech) says it won't hurt the motor to run it, but some of the earlier trucks had laminated fuel tank liners and it would destroy them over time. Mine has steel tanks so I'm ok. He runs transmission fluid in his two F250's.
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...

He's got a 2000 and a 2002, both 7.3's of course. He's been using tranny fluid in his 2000 for about 50-60K miles with no trouble. He has a 3 micron filter system that he built to keep it clean. I think he said he mixes three parts transmission fluid to one part diesel- more diesel in cold weather. I ran B20 in my 98 Chevy 6.5 for several years. After changing two filters in about 4000 miles it got all the gunk out of the fuel system. Ran pretty good for a 6.5. Still use it on the farm. It's got about 240K miles now.
