A 300-hp diesel truck is used for hauling gravel from the rock quarry to a stockpile at a paving operation. The crankcase capacity is 6 gal and the expected time between oil changes is 100 hr. a.- b.- Calculate the gallons per hour of lubricating oil consumed. The fuel consumption for this operation of the truck, if the truck were dumping its bin with excavated soil at 1 minute per cycle operated at full-power, with the rest of its 12 minute round-trip cycle at 15% rated power between quarry and dump site locations (Assume a time factor of 1 on average per day of usage).
