I received my UOA the other day via email from Fluid Life. The caveat: I was under no illusion of what I was expecting this to be. The truck had 48,545km on it with 24,238km on the oil. PetroCan Duron SHP 10w30 semi synthetic CK4, CES 20086 approved. So I expected the wear metals to be elevated as there was still some factory fill in there. What I was really interested in was viscosity, fuel, TBN/TAN and soot. This index was using the Fleetguard LF16035. The next change has the Hastings LF608.

Now I tried to attach the report but for some reason it would not upload so I will see what I have to fix. Anyways I had labelled the oil as 10w30 but they tested it as 15w40 and flagged the drop in viscosity. I never received TBN/TAN and now see I have to call ahead to order this as an extra. The viscosity advertised for the oil is 80cSt at 40C and 12cSt at 100C. The oil tested 76.4cSt and 11.47cSt respectively. So at operating temp the oil was holding strong in my eyes. It was still well within the condemnation limits set forth by Cummins for a 30 weight.

Fuel came back at 2.87%, which could account for the slight reduction in viscosity but really the oil appeared unaffected. Cummins specs 5% max so I am still within limits. Out of the 24,000km, about 12,000 is towing. That breaks down to about 1800km with 20k lb and the rest at or near 10k lb. There is a full winter of use, a few unaided cold starts around the -30C mark, the rest having the truck plugged in. We idle a lot in the cold as well.

Soot was .59% which is well within limits. I think they spec 3% max.

I have not spent much time looking at which additives PetroCan uses but they seem close to Fluidlife's typical averages. Zinc was down to 1230 from 1270ppm, phosphorus 987 from 1150, calcium was 1060 from 1070ppm. Now they say these numbers are for the 15w40 SHP but that should fall in the same bracket as the 10w30 SHP.

Potassium was 124ppm, aluminum 45ppm, iron 106ppm, copper 124ppm were all flagged high. Sodium 2ppm and lead 1ppm. While most were high, I am not worried until I have more tests done over the upcoming changes to establish trends. What I wanted to see and did was the 30 weight oil held up well and did not really lose much viscosity with use and fuel dilution.

I have never seen potassium so high in any UOA. You might have a coolant leak even though sodium is non existent.

Metal numbers "should" settle down with the next service. The iron number I thought was a little high though...for what was about a 15,000 mile interval, I'd want to see that number eventually under 45..with 30 being a better target IMO. Too bad they didn't get the TBN/TAN for you. Every now and again I have to have that fight with Polaris as suddenly my samples will come back missing one or the other....even when I specifically ask for both.

Will be interesting to see how the Hastings hold up. After switching away from Fleetguard to Wix XP...I have switched back to Fleetguard (post about the results coming soon).

Thanks guys. Unfortunately I have to wait 3/4 of a year until the next change as that seems to be how long it takes to get the 24k. I expect the wear numbers to settle and will monitor the coolant as Fluid Life suspects its ingesting coolant due to the potassium. But if the level is consistent I hope to see that drop.

What I am aiming for is to see how well a 30 weight holds up in the 6.7 ISB. I like what DNewton is up to with his Dirtymax and like to dispel the classic "Diesels can only run a 40 weight and I cant have good results unless I run some expensive 5w40."

Buying in 4 liter jugs, the 10w30 runs about 4.7$ a liter (price is up 20 cents a liter since last year). To get into the 0, 5w30 and 40 weight synthetics from PetroCan you are already north of 6 an 7$ a liter. If I can get good all season results then I see no need to spend that money.

I have good news for you, Brian. I feel confident saying that the potassium and some of the aluminum is coming from the intercooler.

My Detroit Diesel showed lots of potassium in the first couple of samples, too. The lab's comments said that the potassium and aluminum were leached from the intercooler and Detroit's literature said that would be the case as well.

There may be differences between our intercoolers but I'm betting that they're similar in materials and that's where the potassium (and some of the aluminum) is coming from.

Specifically, it's the brazing flux in the intercooler that has the potassium, aluminum or whatever else is in the compound the manufacturer uses, where the leaching occurs.

I had never heard of such a thing until I sampled my factory fill and then read Detroit's info about what would be found in it.

Sorry tried to post the UOA. I had to snip it to get my personal stuff off and now the file wont work.

You can quickly rule out a coolant leak by pressure testing the cooling system. IMO it beats watching the level and/or waiting for another UOA. 2cents
