Considering how costly diesel fuel has become, there's literally no good reason to let any go to waste, right? That being the case, we were happy to see the conservation efforts of one man in the San Francisco Bay area, who has just placed eleven gallons of diesel fuel for a reduced rate on Craigslist.org. Why? Well, when his older diesel-powered Suburban's tranny went south, he had fuel left over in a few containers he kept in the back. Since he won't be driving that vehicle any longer, he has no need for the oily stuff. Why not let it go for a little extra cash? So, if anybody near South San Jose has a need for some discounted diesel fuel, check out the original ad here. Tell him AutoblogGreen sent you... just kidding. Thanks for the top, Soo!

I don't know about you, but the idea of diesel particulates (soot) lodging themselves on my brain doesn't sit well with me. While scientists and researchers have known for some time that diesel soot clings to our grey matter, just recently Dutch scientists were able to convince 10 people to sit in a room filled with diesel exhaust so that they could monitor their brain waves. Not surprisingly, their brains showed signs of "stress" just thirty minutes into this operation. We're not going to argue with these results... in fact we thought it was just common knowledge that breathing exhaust fumes, whether from either gas or diesel burning cars, was a bad idea. Ah well, at least we now have scientific data on the topic.

Envirofuels claims that their product, DFC (Diesel Fuel Catalyzer), when added to diesel fuel, "improves the combustion process and reduces friction, increasing fuel economy while reducing emissions and engine wear." It does this with "a catalytic reaction and a surface conversion." How does this help?

Good question, and here is their answer: "The catalytic reaction optimizes the heat release rate, which leads to increased power, reduced emissions, and increased fuel efficiency. The surface conversion forms inorganic polymer complexes that converts the surfaces of ferrous and non-ferrous metals. These complexes smooth and passivate the metal surface, improve reflectivity (emissivity), and reduce oxygen reactivity, resulting in a reduction of friction and a more complete combustion reaction."

Honestly, their site is so full of information, via pdfs, links and charts, I suggest you check it out for yourself and make up your own mind about whether their product makes sense or not. It seems like an additive, like the ones you can get at any auto-parts store, except that they are targeting very large fleets and operations touting the savings and better emissions on a large-scale.

When it leaves the refinery, ultra low sulfur diesel (ULSD) should be under the required 15 parts per million limit. But on the way to the pump it could pick up a few more parts. Apparently the tankers hauling ULSD also transport jet fuel and off-road diesel. By one estimate, every change of hands could add 2 ppm of sulfur. Not every fleet company takes the time to flush the tanks and delivery hoses when needed. Additional labor and logistical costs are hindering efforts to sort out the schedules and procedures. The key, according to one analyst, is to load ULSD behind other low-sulfur products like ethanol and biodiesel, then segregate other high-sulfur products. Getting uncontaminated ULSD diesel into your tank is critical as the modern emissions use high efficiency catalytic exhaust systems that can be contaminated by sulfur. What's making it into your tank?
