Eot & ect GVW is 20000# is this to high?

[Bluecat1]

2004 6.0, 15k miles ago 4in Mbrp exhaust,no cat or muff, Egr delete, new oil cooler, flushed coolant and put coolant filter on.

I've recently bought a SCT tuner, I'm running the caned tunes, tow package + 65hp

Truck and trailer weighed 20000#

My ect was around 210 and eot was around 230! IS this to high?
Just seems to be a big gap between the two?

Everything I have read says no more then 15 degrees when running on a flat road at highway speeds for 10 minutes or so unloaded. Try that scenario and see what it reads.

Did you delete the egr cooler too?

The 15 degree delta does not apply with a trailer on

[jetjock15]

Those temps are fine, and expected towing that trailer. I wouldn't expect to see any higher temps or more spread though, that trailer is not super heavy. Real question is what's your delta unloaded?

[6.0f250firstcar]

Yeah it doesn't apply with a trailer on but yeah check out your deltas unloaded at 65.

What are you running for oil? You should be running a synthetic 5w40. It is much more capable of protecting your engine at high temps than dino oil. Overall your temps are not out of line for that weight.

Running rotel oil not synthetic though, egr cooler was deleted, empty my deltas are 5-8

What is hot for eot?

I ran up a long long grade today. From Las Vegas to Baker very long IMO and I ran up 50-60 MPH towing my 40' Montana 5th wheel. Loaded down and towing a dirt bike trailer behind. About 15k plus the truck and the highest I saw was 229. Rotella t6 oil and mbrp 4" no CAT no other mods. Stock tune
Just FYI to compare

With oil temps of 230* plus I would really want a synthetic oil in the truck, but with all the evidence concerning how much better synthetic oil is than standard dino oil for these trucks I don't understand why anyone would continue to run dino oil in them.
