Wildly platform dependent but I once emailed Mobil about a track day where my car exceeded 300 degrees.

They said that was no problem. Engine is still going strong 8 years later...

What I have heard form guys that race and use their diesels in heavy use situations, 265*-280* is getting too hot, but you should never see close to those temps. I was using Rotella 10w-30 and changed it to 15w-40 on the trip where I saw mine climb. It did bring my temps down about 5*, but nothing major. I wouldn't even worry about it....just keep on going. I am not even sure I would spend the money on a UOA unless you just want peace of mind at this point.

There is the other thread from back in March.


Thanks for the info Cowhorse01...interesting reading. One time during the trip the outside temps were 105 degrees and I was pulling the trailer up into the Siskiyous. Not an idea situation for towing. The EOT readed 225 at one point until the clutch fan kicked in and it brought it down a few degrees. I think I feel more comfortable now knowing what was said in your thread.

The 7.3 was originally speced for 30 wt., you're not doing any damage running 10w-30 with the temps you've reported.

Personally I use 10w-30 in my 7.3 and 6.0, with outstanding UOA results, but if running a heavier oil makes you feel better go fro it, your 7.3 won't care.

I think I am going to send in an oil sample and see what the results tell me and go from there.
