Nope, not unless you have a air cooled oil cooler like the BPD. Think about it... the oil is being cooled by the coolant. The oil can never get cooler than the coolant.
When the truck is stone cold, before you start it, look at the EOT, ECT, trans temp, IAT, ambient temp ,etc... They should all be fairly close. I suspect you EOT is reading artificially low compared to the ECT.
