I know everyone is hyped about BioDiesel... at least... the people who A) Actually know what it is, and B) Don't actually drive anything that has to burn it.
I'm not complaining, I swear... I only loose about 3-8 mpg in my '97 7.3l Powerstroke (that has been known to run 22+ mpg on straight diesel, and has even made a phenomenal 27 mpg highway cursing), and quite a bit of engine throttle response, depending on the percent of Bio blend I have to buy. My 'Strokes don't like the algae fuel.
For those of you who don't know, and think I'm batty, yes, I
did just say 'algae fuel'. Here in West Texas its been kind of on the down-low, however, since the first of the year I've said "Change the fuel filter and see what happens." so many times I feel like I'm on repeat. Biodiesel is made from a variety of things: virgin oil, algae, sewage... just to name a few, and not even going into the experimental sources. Don't even ask me to pretend that I understand the complected chemistry behind it all: I don't...
yet.
I have run across claims of fuel efficiency increases... I would like to see the data to back that up, rather than just claims, as well as someone detail the systems on the engines with increases. I'm watching my fuel economy drop, so you can see my skepticism. I
am aware that there are several engines in R&D right now that will run on 100% biodiesel and they are shooting for 40+ mpg with them. I sincerely support this! I would love to see biodiesel bring the price of diesel per gallon back down to under $2 (I would really love to see it about .89 again, but I doubt that will ever happen).
The biggest issue I have with biodiesel is the bacteria. Diesel is prone to doing all kinds of strange things if you leave it alone in a tank long enough, but biodiesel seems to be even more prone to that than petrodiesel. For one thing, biodiesel is capable (and does it a lot) of absorbing water on a molecular level. Which you can imagine isn't exactly great for trying to inject it at 20,000 psi through an orifice generally too small to see with your bare eye, and then try to explode it in the cylinder. Older diesel engines don't much care for that, even ones with much lower injection pressures, and larger orifices in the injector nozzles. (Sadface for my 1990 Indirect Injection 7.3l Diesel F-250.)
Right now, I'm advising all diesel owners to carry at least one spare fuel filter in their truck, the tools to change it with, and praying you all know how to change it in the dark. So if you aren't familiar with the procedures, you might want to go over that owner's manual that has never been out of the glove box.

| Filter out of '96 Powerstroke with DieselSite's OBS CPR system. This filter came out when I drained almost 2 gallons of water out of the 26 Gal tank on the truck, after getting two bad tanks of Biodiesel in a row (from two different places, in two different towns). |
I believe most of the new medium-duty diesels are coming off the lot prepared to deal with up to 20% (B20), but the older engines don't much care for it. Atlas, the '96 my mother just bought in November, happily came to us with DieselSite's OBS CPR system, which includes a great water separator on the rail, and filters with 2 micron filters. What a life saver! It kept Atlas out of the weeds when he got some nasty fuel just like my blue truck did. Sadly for my blue truck, it is still running the stock fuel system, and it gladly went into a dramatic, screaming limp-mode when it got bad fuel and barely rolled into an O'Reilly's for me to get a fuel filter. (Because I don't take my own advice...)

Since the older trucks often use filters that only catch rocks and chickens, you might think about shopping for better filters, and looking into a water separator more efficient than the OEM one. I can defiantly tell you that while the CPR has a price tag that makes all the do-it-yourselfer's suck in a gasp of air, I have one sitting in my parts room/office/study/specialty tool room that is going on my white truck because A) Its a great system, B) I just spent a bunch of money on new injectors for Beastin, and I don't want to blow the tips off on my first tank of B20 with too much trash in it.
Lastly, I want to talk about treating your fuel. There are LOTS of fuel treatments out there ladies and gentlemen, and I don't dislike any of them... I just only buy Power Services products. I've been treating my diesel for a couple of years now with their Diesel Kleen cetane boost, and just recently became a huge fan of the Clear Diesel and Bio Kleen... Clear Diesel now lives in my tool box next to the cetane (white arctic formula for winter and gray HP for summer).
Power Service's products can be picked up pretty much anywhere you get auto or diesel supplies, from O'Reilly's to Tractor Supply, so next time you're out, pick up a gallon - it treats about 250 gallons of fuel, and usually runs about $20.

~Great products, they do their R&D right, and couldn't ask for better customer service. Also, they have lots of things in the works for the near future.
In the meantime, take care of those diesels, and instead of changing your fuel filter every-other oil change, start doing it
every oil change. Filters, no matter how expensive, are still MUCH cheaper than injectors. Soon, hopefully as the demand for diesel increases, the quality of biodiesel will improve, and the truck stops will get on board with treating their tanks. I'm all for improvements, especially if it makes it cheaper at the pump.
I will leave you with a photo to ponder... Do you think that parking this rig on a pallet will help this gentleman with the fact that he is buying fuel from a the very Stripes that created the black fuel filer in the photo above?
