Difference Between EOT and ECT
My 2005 F-350 6.0 has 135,000 miles on it and the differences between my oil and coolant temps are as follows:
Up to approximately 50 mph = 7 - 9 degrees.
Up to approximately 60 mph = 10 degrees.
65 - 70 mph = 11 - 12 degrees.
From all I've read, these readings seem high and probably indicate partial blockage in the oil cooler. I'll be installing a Sinister coolant filter kit in a few days. If the differential between EOT and ECT doesnt get any worse, is it possible I won't have to replace the oil cooler? By filtering the coolant, is it possible that some of the blockage will be cleared? (Probably just wishful thinking, huh?)
Thanks for any help.

The test is up to temp, steady 65 on level ground. From your numbers you are good. 15° split is the max so you're in spec. but I'd be keeping an eye on it myself. What are the actual numbers?

With engine up to temp and running 65 on level highway, the difference shown on my Edge Insight monitor is 11 degrees.

I installed the mishimoto t stat now my eot runs higher than it did before. Before it stayed around 200-204 now its in the 208-211 range.

The temp spread of 15 degrees being the threshold is only valid if the coolant temp is at 190. If you raise the coolant temp to 200 with an aftermarket thermostat you have to determine a new target temperature spread.

Curious where you got that info. Not saying it's false but the first time that I've heard it.
