Good points 2eye. It seems the oil burners and blown motors seem to always follow the same scenario:
1) Owner does not change their own oil or care to lift the hood, uses "iffy" lube type places.
2) Owner bought the truck used & does not know the full history of the truck.
3) Owner is aware the engine uses oil, does not troubleshoot issue.
4) Owner noticed some engine noise after an extended, high speed travel, no oil showing on dipstick, engine has spun a rod bearing.
