Tips for Using Biofuels in Your Corporate Fleet

Converting a corporate fleet to biofuels is one way to reduce emissions, and improve your corporate social responsibility. Biofuels are not a panacea by any means, but can be locally grown, locally processed, and are completely renewable, helping to break your company’s addiction to oil.

For smaller companies looking to do biofuels for deliveries, sales calls, or other local business needs, they might consider picking up a diesel vehicle and committing to biodiesel. Biodiesel is typically made from grease, used oils, or high oil content agricultural products like rapeseed (canola), but can also be made from algae. It’s easy enough to find a work vehicle that takes biodiesel–simply find a diesel vehicle. B100, as pure biodiesel is called, or B20 (20% biodiesel, 80% diesel) can be used interchangeably in that vehicle at any time with regular diesel fuel.

What are the considerations in switching to biodiesel? According to Pacific Biodiesel, it’s a fairly seamless process:

The main thing to remember is that biodiesel is cleaner than diesel fuel, and as such, it will help to clean your engine and other internal parts (fuel lines, etc.). As a result, biodiesel may dislodge gunky deposits that diesel fuel has been depositing in your engine, which means you might have to replace your fuel filter fairly soon after the transition. Pacific Biodiesel recommends buying a fuel filter and carrying a spare in your trunk in case deposits do come loose and cause performance issues.

Ironically, this is not unlike the problems some people face with clogged arteries. Blood clots caused by high saturated fat diets and unhealthy lifestyles can sometimes break free from arterial walls and cause health issues. Biodiesel, then, is the artery cleansing anti-cholesterol medication.

They also recommend idling the car for a minute upon startup and end-of-driving, slower acceleration from red lights and stop signs, and not letting the tank get below 1/4 full. Of course, these are recommendations made for conventional fuel vehicles, as well, so as noted…a switch to biodiesel is fairly straightforward.

  1. Solazyme delivered over 80,000 liters of algal-derived marine diesel and jet fuel to the U.S. Navy, constituting the world’s largest delivery of 100% microbial-derived, non-ethanol biofuel. Subsequently, awarded another contract with the U.S. Department of Defense for production of up to 550,000 additional liters of naval distillate (HRF-76 marine fuel).B100, pure biodiesel will not make the mess you are talking about

  2. Warning… most diesel engines can’t take B100 and lots can’t use B20. Due to EPA emission standards, many exhaust systems clog and computers have fits over high levels of Biodiesel. Winter running also is more complicated when including Biodiesel as the winter additives to combat gelling have to be used at higher rates, offseting cost savings over regular diesel. One should always consult their owners manual before filling up with Biodiesel. Several of my fleet vehicles are B5 or less trucks. The previous owner tried to run B100 and B20 and caused the injector system to fail and considerable amount of repairs to be footed by the 2nd owner (me) as a result of overuse of Biodiesel.
