The co. truck all of a sudden started using oil (3 qts less than a 1000 mi). No sighn of leakage, no blue smoke hot or cold, no excess black smoke on fender, truck has 60k and to this point we have never added oil between changes. The truck gets worked real hard often and some times overloaded. Truck gets serviced at the dealership using there oil and filters. Got any ideas before we take it to dealer. Only mod's is KN air element that they service and said was ok to run. Thanks Much

Gene..thats alot of oil, the first thing they will likely do is start an oil consumption test. Basically fill it up, document it and send you on your way. Have you bring it back in XX miles or XX hours and see how low it is. IIRC gm tolerance is 1 qt per 100 hours.. I think. But that is only for properly maintained vehicles, under 3/36 warr... blah blah blah... I do agree, that does some excessive..
