[QUOTE="Pstrke96, post: 1217831, member: 15655"] I get 8-9 mpg loaded, however I credit a lot of that to the 9sp trans. I don't shift out of 8th until55 mph and have had it doing better than 80. The broad too end gear keeps the rpm relatively low at normal cruising 65 ish. When I left my gramps company this truck had 498k on it l, never any smoke but black. In the 8 years and 90k I put on it all it ever got besides pm was a water pump. The only downfall I can think of is the cylinders are not sleeved so an in frame isn't pheasable, that's just food for thought like I said never any trouble with mine wish we had more like iy [/QUOTE]
