When I converted my ?93 Bronco to a 7.3-liter Power Stroke diesel, one of my goals was to eventually run it on biofuel. Of course, that wasn?t my main objective.

Something to the effect of, ?This looks like a 12-mpg Bronco, but it?s actually got a diesel and furthermore it?s running 100-percent biodiesel (B100), which the California Air Resources Board recently determined can reduce ­carbon emissions as much as 81 percent compared with petroleum.? Unfortunately, I am physically incapable of applying a bumper sticker to my vehicle, on the grounds that bumper stickers correlate with mental frailty, mega­lomania, and probably poor personal hygiene. Perhaps sustainability and emissions weren?t my priorities at the outset, but running a 7.3 in an open-top vehicle makes you intimately familiar with that engine?s major shortcoming: It?s a foul thing, a 444-cubic-inch industrial zone. One day, sitting at red light in a Mazda, my three-year-old in the back seat declares, ?I smell a Bronco!? Sure enough, there?s a ?90s Power Stroke pickup on the opposite side of the intersection.
