My results came in today. I've been interested to see how it compares to Fritzs, even though he has so few miles on that oil. We have the same year engine, almost the same miles on the engine, and mostly in town use. Not New York level of city, but we have plenty of stop signs and stop lights. This was an annual oil change with about 2/3 of the 3,213 miles being in town use, short trips. No towing but I do drive it like sports car from time to time and not much unnecessary idling. Rotella T6 5w40. There appears to be a big difference in moly, potassium and boron compared to Fritz, is the 15w40 that much different?
The notes basically said wear metals are low, as expected for oil with low miles on it, and the 5.5 TBN is strong, oil is fine. They said that calender time isn't much of a factor on OCI for modern engines and I could try 5k instead.
You put on ~3k miles/year? If so tough call as I believe Ford's OLM calls out to change the oil at a maximum of 1 year for time in service. Having said that, your UOA looks like T6 should and your engine looks to be in excellent shape. If it were me I wouldn't exceed the time required to change the oil as long as it is under warranty. I wouldn't compare your UOA to Fritz's since I'm sure he's adding some type of additives to his sump.

Yep, the most I put on it in one year was the first year, about 5k miles. Overall average calcs out to around 3700/year. I wish I had the need to drive it more, but this is it for now. We have a small SUV that sees about 7k/year between my wife and I, and my little truck got 800 miles last year haha. I agree, the vehicle year, miles on engine, and mostly in town use is where the similarities end between mine and Fritz's truck. He has a lot more truck with a lot more done to it.
I plan to stick with the annual OCI, to satisfy Ford and myself. I've never gone 12 months between oil changes on any other vehicle. I was curious to see how it looked at 12 months, make sure nothing was abnormal, no fuel dilution from the short trips, city use or whatever. Glad to see it's all good.

Looks good. Even the viscosity levels in yours is good. That makes me wonder why mine has been so low…

That is interesting, I do wonder where all the potassium came from. Boron and Moly you at least see a little more frequently in oil blends, potassium not so much. Usually it is a sign of a coolant leak or he got a banana sucked into the intake. IIRC good olde Rev-X had a significant slug of potassium in it.
Mine is at 12% now, will be interesting once it hits 0% to see how many miles it went and get a sample out to BS to see the final results. I know the reason for slightly lower viscosity on mine was due to having 10W30 from the previous oil change still in the block. Doesn't take much to dilute the mix. This OCI is mainly daily driving @ 60MPH 120 miles a day, so good and hot engine to burn off any water, and reduce fuel dilution from cold ring bleed down. The last one @6400 miles showed trace fuel.
Not a big fan of oil analysis, my thinking has always been use the money to buy new oil.
but, I broke down and did one just to see what I could learn…learned nothing…oil is fine…no metals (engine damage type), some silicon (thanks ford air filter), but nothing to get e cited about.
Comments welcome.
What comments did Blackstone leave? Considering the viscosity drop, flash point, elevated silicone, all with only 500 miles on the oil...I would think they gave some feedback.
Would be interesting to see an analysis on this oil. Motorcraft 10W30 diesel oil with about 5,000 miles on it. Truck has 88k now and is bone stock. I'm assuming it's fuel that is causing my crankcase levels to do this so fast. Quite annoying though.
Jumping in here. I've been a Blackstone oil analysis guy and was made aware that their fuel dilution testing is very subjective, mine has always come back at .05%. I sent my last sample out to Oil Analyzers and received it back showing 5.3%. Driving conditions are similar. I have a reasonably high idle time (~20%) but otherwise my truck is hauling the toy hauler or running down the freeway empty. Last two samples were at ~7,500 miles on the oil.
Thoughts? Should I just change my oil more often or is this nothing to worry about? Oil level does not seem to change on the stick even though this is more than half a quart being added to the system.

Generally speaking 2 to 2.5% is considered the upper limit of what you want to see for fuel in oil. A single data point is just that, the trend is more important. Assuming the wear rates aren't elevated I wouldn't lose any sleep over it, given the amount of idle time you have I would run 5k OCIs since I think that puts you in the severe use group.

There is always talk about idle time, but I've never seen my truck perform a regen while idling. Not that I check every time but it seems we are quick to blame idle time but I thought it was regen that put fuel into the oil. My truck almost always regens while I am on the highway (I monitor soot level and regen status with the Banks iDash). Just curious what else causes fuel in the oil. Wear rates look great. I'll do a deep comparison to my other samples when I have some time.
And since there is such a difference with how the analysis companies determine fuel % I'm wondering if we have all the information we need.

It isn't just regen that can be a source of fuel in oil as a result of idle time. Wet stacking can occur during extended idle, if the engine isn't warm enough fuel can make it by the rings and into the oil. Regen is only part of the issue, that is why there are high idle options available to keep engine temps up. Especially on common rail engines that really don't generate all that much heat at idle, my 2004.5 CR Cummins (which obviously had no DPF) would fuel in oil with extended idling much more than my 2002 7.3 PSD.
IMHO, the trend is more important than point to point.

Makes sense... in fact I use high idle almost everytime the truck idles once it's warm. My previous truck ('06 Duramax) had the same workload as my Power Stroke but without a high idle. Fuel in oil was never a concern and never mentioned in an oil analysis even with 10K oil runs.

IMHO, if the wear rates didn't materially change I wouldn't get too excited about it. Maybe take another same at 4500 or so miles (depending on usage) to see how things are going. Sampling risk is a thing and it is possible this is a fluke/blip on the radar.

I guess what I am getting excited about is the dramatic difference between the Blackstone and Oil Analyzers fuel dilution numbers. I get they use a different method for calculation but one result might change my behavior the other I'd never worry about it...
I did compare to the other oil reports and the wear metals and everything else are very very similar or identical. Same oil, same mileage and roughly the same use case.
