Another oil temp thread cm2350

I have read several of people complaining about high oil temp on these engines -like 250* I was told locally that there is more than one oil stat for the isx15 and that earlier versions were typically cooler. Anytime mine is working hard in this 100*+ heat , which can be close to an hour between small towns, uphill, heavy and wind, mine sits right at the redline 250 or so. Cools back to 240 or so going through town, then back up. Water temp never exceeds 209 no matter what. Cools down as it should when fan kicks on. If you lock fan on oil temp will come down to 235 or 240 but not during normal cycling.
I was told a cooler oil stat would help considerably. We work our trucks hard and change oil every 10-12k miles. 250 continuously seems it would really take a toll on conventional oil. Does anyone know a part number for a cooler stat? Thanks.
