I'm just wondering what temperatures you guys are seeing with after market oil temp gauges. I'm going to be installing one with the temp coming off the port on the oil filter housing. TIA

 

I installed mine about 8k ago. I have an isspro mounted on top of filter housing. Normal crusing at 73 mph unloaded with outside temp of 80 oil will run 207-208. Pulling 3k at 77 mph with outside temp at 85 will run 215. Pulling 3k in colorado near lake city at 68 on long grade 235 deg with outside temp at 75. Running 68 between garden city and dodge city with outside temp at 104 and pulling 3k oil temp 225. 207-208 is pretty much the norm for my truck.

 

200-210 is normal for my truck also and highs up to 230-235 when loaded down with the toy hauler.. Scotty
