Delta is not a reference point with external oil coolers dudes... the oil and water are not going through a combined cooler, so there is no reason they should be close. So with the BPD external oil system, delta is not applicable, it is a measure of nothing. More like a conventional motor. My LS6 in my CTS-V runs 230 EOT and 190 ECT all day long, and that is normal... Once the 6.0L engine "oil/water cooler" is removed like in the BPD kit, there is nothing relating the two fluids except the fact they are flowing through ports in the same block. Make sense?
and as far as "normal oil temps", to the OP, you are fine, towing 12k or more, the temps are going to be higher, EOTs under 260 are fine. Textman, dude, where are you taking your reading? and when was the last time you weighed your trailer bro. Facts are the most helpful thing we can provide each other on this forum, nobody is pulling 15k at 209 EOT, sorry bro, something is wrong with your reading. Normal unloaded temps are 190-200, you don't pull near Max combined GWVR and only run 9 degrees hotter, your system of data capture is corrupted or something...
