Everytime your vehicle sits for more then a few hours you start it with "no oil",at least no oil pressure,and don't forget when "you" do the oil change it is started with no oil,and that seams to do no harm when you do it so how is it different when a dealership does the same thing?
actually about 80-90% of the wear on an engine occurs between the time the key is turned and the oil reaches the bearings - once the oil is there - there's virtually no wear.
So if you have a situation where the engine was run dry even for a minute or two - then you've destroyed the crankshaft bearings.
once the bearing is destroyed it's a fairly quick for steel to steel contact to overheat and damage the rod which breaks and goes though the side of the block.
Although when that initial damage occurred would be the question, but the timing of oil change/150 mile drive/ dead engine - implies at the oil change something went wrong
(unless your oil pickup dropped out of your oil pump - but hey that's a Chevy thing)
Oh yeah - and CRD folks blame the techs because Jeep Techs cause a lot of problems - due to the non trivial detail that they were never trained for diesels - 1 hour videos don't count.
and the MIT grads I know don't change their own oil.
in fact most of our maintenance techs - don't even like the idea of any Engineer MIT or not, getting close to any machine at all - they lock up and hide the tool boxes
