I got my first analysis:



"JIM: Potassium, boron, and sodium are all from the Rev-X you added. They're harmless to your engine, but because coolant shows up in our tests as potassium and sodium, the presence of Rev-X can make it tough to spot a coolant leak. But with coolant comes wear, and your engines metals look fine. Iron is a touch higher than averages, which are based on 5,400 miles, but if your engine works hard, that could certainly account for it. Fuel dilution measured at a trace, but no other contamination was found. The low viscosity is harmless. Try going 7,000 miles next time."

Thoughts and comments are welcomed.

No shock t6 sheared, in general 5w40s shear more than narrower grades. Iron is up a bit compared to other uoas I have seen on a 6.0 but still in the normal range. Looks fine IMHO.

Anything I should do different? The truck also has high coolant PSI...

Your oil report looks fine.

I have archoil in this oil and I'll be sending in another sample.....I'm thinking about going to 7500 mi.

How high is your coolant pressure? Does it look like there is any oil in it?

The problem with Revx is its use of sodium and potassium so the usual smoking gun of coolant contamination is nullified.

Here is mine with AR9300 in this change. I seem to be showing a fuel issue in the oil, will be watching this closely. Pleased with the wear though.

15-16. There is some kind of milky, bubbly film floating on top in the degas. My delta is 7-8.
