Fleet managers across the United States are examining ways to offset the cost of surging fuel prices. Government incentives to use alternative fuel, the potential for fuel shortages, and company initiatives to be ecologically friendly are also contributing to the transition to bio-diesel fuel.

Bio-diesel can consist of oil from soybeans, rapeseeds, or even animal fats. Although, diesel engines have operated on a variety of odd fuels, for example granulated coal, bio-diesel posed unique problems. Major issues with bio-diesel fuel are fuel filtration, storage life, storage temperature and the affinity to hold water.

Diesel fuel supports bacteria, termed microbial growth. The bacteria clogs fuel lines, filters and injectors. B20, diesel fuel with no more than 20% biological content, supports these microbes readily. Bio-diesel is less stable over time. Significant degradation occurs with fuel older then 90 days. In cold weather stability of the fuel is decreased. The fuel gets clumpy, like wax, and other particulates come out of the solution. Water, stemming from the amount of humidity, dilutes the fuel, supports bacteria and rusts the fuel system components. In cold weather, the water forms ice and blocks fuel lines and damages pumps.

One of Auto Truck Group's customers is actively pursuing the transition to bio-diesel fuel modifications to their fleet. The fleet is shifting their diesel capable engines to handle a diesel fuel with a higher percentage of biological content. Auto Truck Group is making several changes so the engines can operate reliably. Auto Truck Group has made changes to the fuel filters, electrical systems, and have added quick connect outlets to ease crankcase oil sampling. "We're pleased to be involved with this important incentive and the new technology accompanying it," said Guy Chollet Chief Engineer at Auto Truck Group.

Auto Truck Group, headquartered in Bensenville, IL, has been Making Trucks into Tools since 1918. They offer extensive experience, knowledge, excellent service, competitive prices, and tremendous value to their customers. Auto Truck Group's five locations provide convenient access for up-fitting in the work truck industry. For more information please visit,
