With that overwhelming data, Dufour moved forward with additional Kenworth T440s with CNG. “We have been running 27 of the T440s since June of 2012 and they’re doing great,” he said. “And, other than having spark ignition and spark plugs to deal with, and a different kind of engine oil, there really is no difference in maintenance practices. From a fuel tank standpoint, they just need to be monitored and maintained, but our technicians have been trained and certified for that duty.”
“We’ve made a long-term commitment toward CNG,” said Dufour. “We have placed additional orders for Kenworth T440s, and by 2015, 90 of our 105 trucks will be CNG-powered.”
