Blackstone oil report
Got my oil report back yesterday and have some questions.
Was using rotella t 15w-40 oil with 5000 miles.
2.0% fuel in oil-they said this could be caused from city driving or idling. I drive very little city and only idles upon warm up(about 10 minutes), should I be concerned?
They said copper and lead were high but may be due to new parts wearing in. Copper 23, lead 6. the average is 4 & 3.
Engine has 8000 miles on it.
Copper and lead mean main bearing problems doesnt it?
Any help or opinions welcome.
Thanks, JAY

Yes 2% is considered high. Are you using any kind of tuner, chip, fuel box?

MRKnight-
IMO you are a prime candidate for oil analysis based on your reported poor fuel mileage. High levels of fuel in the oil can be an indicator of injector(s) failure. It should be noted that a lot of 6.0 owners have reported 2-3% in 5,000 miles (myself included) with decent mpg results. An oil analysis on a your truck could help figure out why your mpg is low- Or at least tell you that there is not abnormally high levels of fuel in your oil (among other things). The narrative that comes with the analysis from Blackstone is quite informative.
Good Luck and please report your findings-

I suspect there is a typo in your post but let me confirm, you have a two year old PSD with 8,000 miles on it. If that is correct, expect this kind of analysis. You are only putting 4,000 miles per year on the engine. The injectors are going to leak some, cold starts are going to add up, and you apparently don't drive it far when you do drive it. Your soft wear metals will also be higher because of this driving habit. If there is a typo and you have an 05 PSD, I would suspect a leaking injector. The soft wear metals would be break-in and should taper off to an average at around 20-25,000 miles. Rotella that you are using is a good oil in the PSD. We run it in our chase truck at work. Wear metals are well below universal averages across the board with 5,000 mil OCIs. Our drivers are not known for being gentle with the trucks either.

FLASH, no error on year. 03 PSD, truck has 20,000 miles but engine replaced at 12,000 miles because of metals in oil pan, 3 rear seals.
Yes my trips are short to work and back but truck and tranny at full temp, this is why I`m concerned about the lead and copper.

I thought Ford had stated 6% fuel in oil is considered normal. Most reports I've seen here have 2-4% and were considered normal from Blackstone.

Two questions: I've seen this "Ford allows 6%" thing on plenty of threads but I've yet to see any official Ford documents to that effect. Can anyone cite an actual reference on this, other than "dealer/service rep told me"...?
Second question: it's my understanding that the Fuel in Oil calculation is a proxy measurement based on a combination of flash point and viscosity analyses. If this is true, I wonder if oil shearing has any affect on the Fuel in Oil calculation, and if it's not true, excactly how is the Fuel in Oil analysis performed?

Seems plausible. I'm no chemist, but as I understand it, shearing is technically the reduction in viscosity due to physical "squeezing" or pressure that literally shears the long hydrocarbon molecules apart and makes them shorter, thus reducing viscosity (and the oil's protective lubricating ability). This is different from viscosity reduction due to dilution or heat breakdown. It does seem like dilution may make the oil more shear-prone, maybe via the spreading out of the oil molecules which results in greater pressure on fewer molecules(??), but I'm just guessing here. Probably depends a lot on additives, too. No matter...fuel in oil sure can't help anything. 
On the other hand, if Blackstone is using viscosity and flash point to calculate fuel in oil, and if oil shearing is higher than usual in a 6.0L engine, might this skew the fuel-in-oil calculation? Or is flash point a control here? Dunno....

This is an older thread i have started reading, my first report came back with 2% also. I do a lot of in city stop & go driving. will report on next report. I do know that when I change the oil it is much more runny than that I take out of my other vehicles.

Thanks for that thread Tinytrxie, now have more questions.
Looked at my silicon reading and its at 51, the average is 11. This is from contaminates coming through air filter I believe. Since I`ve got an aftermarket intake system(AFE) I`m wondering if its not filtering enough. I dont drive in very dusty conditions.

If you have 14 qts of oil in you engine, x's 2% = .28% fuel which is
9.6 ounces. I got that one time doing alot of short trips. That is not
considered alot of fuel in your oil. My last report was less than 0.05%
Alot of short trips and idleing will cause this. This is what I have
found out.

I do believe that if you drive less than 10 miles per one way trip the engine doesn't get hot enough to burn off exess moisture and fuel in oil. Yes your temps would be up to norm in about 2-3 miles but not hot enough to burn off excess. I drive 14 miles work everyday and I asked a diesel mechanic about his before buying our first diesel pickup.
