amt tech wrote does anyone know what the optimal speed is to obtain the best fuel eceonomy with the 2001 dodge ram 2500 4x4 diesel cummins 5.9 i have had many discussions with people who tell me one speed and others who tell me another. my truck has a 5 speed tranny. i am aware of the fact that diesels do not like higher rpms.... thoughts anyone the cummins powerspec program says the isbs best cruise engine speed for mileage is from 2100 to 2400 rpm for vehicles 10000 gvw and under. i believe thats true if your loaded or towing heavy but ive found the best fuel mileage at 2000 rpm or below when empty. powerspec report 1.select a gearing combination that will result in an engine speed of between 2100-2400 rpm at the vehicles intended cruise speed mph. 2.for maximum fuel economy or for vehicles operating 65 mph or faster select a gearing combination that will result in an engine speed of approximately 2150 rpm at 65 mph checkpoint. 3.gearing combinations that produce an engine speed less than 1900 rpm at the vehicles intended cruise speed mph should be avoided. 4.note isb is not intended for weight over 50000 lbs. engine isb application recreational vehicle gearing recommendation type line haul typical gross vehicle weight gvw under 10000 lbs. percent time operating off-road or on soft surfaces 10% percent time spent operating on interstate highways 90 - 50% intended cruise speed 70 mph gearing desired fuel economy the powerspec program that calculates optimum gearing based on information supplied initially by the user. any variation between this input data and the actual operation could affect the accuracy of the results and make comparisons with actual operating experience questionable. powerspec does not have the capability of making distinctions in resistance forces and factors affecting energy requirements such as; air resistance due to frontal area or aerodynamic drag coefficient. rolling resistance due to tire construction bias radial low profile radial etc.. air resistance increases due to winds and rain or snow. rolling resistance increases due to cold and rain or snow or due to different pavement types and condition. drivetrain and accessory loss increases due to cold weather. increased fuel consumption due to use of blended fuels and long periods of idling in cold weather. cummins is in no way liable for hardware selections made by the users. specifications should be reviewed with the vehicle manufacturer dealer or with a cummins distributor. -- ken .
