Although it's tempting to purchase the cheapest diesel fuel available, you really need to understand how it affects performance and operating costs. While No. 2 diesel fuel conforming to ASTM D-975 can have the appearance of a commodity, look more closely and you will discover important differences.

"The ASTM D-975 specification sets the requirements for a No. 2 diesel fuel," says Chad Pistulka, product manager, refined fuels, CHS, marketer of Cenex brand products. However, he notes that many OEMs and consumers would prefer to see even higher standards. "An operator can save money with a premium-type diesel fuel that provides higher cetane, better lubricity and contains a multipurpose detergent package."

Joe Fell, Ryan Central Inc., Janesville, WI, has actually given presentations on managing fuel costs at the Chevron Construction Symposium. Ryan Central ranks among the largest nationwide site work and mass excavation contractors.

According to Fell, much more goes into the fuel purchasing decision than price per gallon. "You have to look at your equipment rate right now," he advises. "Fuel continues to be a larger percentage of that rate."

On the surface, a cheaper fuel may appear to lower costs. But if it means more maintenance or less productivity, your overall costs may actually increase. "You have your people cost, your equipment cost and your fuel cost," Fell points out. "You have to weigh that balance."
