Oil Analysis 6.8L
Does anybody have average numbers for a V10? Below are the results from two consecutive 5500 Mile, and 5000 Mile runs respectively. I have been using about 2qt/5K since going to Mobil 1, when I was using Dino (first 15K miles) I would be 1 Qt low at change, but didn't use any more. She now has over 70k. Runs great, no noise, any thoughts would be appreciated.
Element 1st 5500 Mi, 2nd 5000 Mi
Lead 7,4
Chrome 5,3
Magnesium 274,76
Tin 0,0
Silicon 33,20
Iron 82,52
Aluminum 16,10
Copper 25,11
Silver 0,0
Titanium 0,0
Nickle 3,2
Sodium 23,19
I guess what scares me is the high(?) iron, and Magnesium. Although I can't imagine what in this engine has Magnesium. Could be an addative package change in Mobil 1 as this does span several months. I don't have any earlier numbers to look at and couldn't find any others on this site for a V10. Any thoughts would be appreciated.

I think it is interesting that you 2nd round of numbers are lower across the board and I think I know why. Synthetic base stocks like ester have a lower analine number than mineral oil. I think I spelled that right, but I know for sure what it means, The lower the number the better the solvency. This means that a synthetic will clean old deposits better than a mineral oil. Which I think is important. This would cause the synthetic to actualy appear to be inferior to mineral oil on the first couple oil changes based on wear numbers as they clean and carry away old deposits. Maybe more on a dirty engine.

I would agree, except I started using Mobil 1 with about 15,000 miles on the truck, and these two changes were at 67k, and 72K. The only number I am really concerned about is the Iron, the Magnesium is likely and addative package change when Mobil reformulated about this time. I just can't find any benchmarks on the web anywhere for what is "Normal" for this engine. The only data I can find in the forums is for a V8, and it lists 23 as typical for the Iron. I would expect a V10 to be a little higher, but not double to tripplet that. Any insight would be appreciated.

I am using Motorcraft 5w-20. These are my last 3 reports. Reports done by Blackstone. 1st=15,849 miles on truck, 3,158 miles on oil, 2nd=19,067 truck, 3,218 oil, 3rd=22,170 truck and 3,103 oil. Not as many miles as yours but I am not sure I want to run this oil that long.

These reports span multiple towing (6000 lbs), below zero starts, and a lot of mountain driving. Most of the towing was done in the mountains also. I have an 02 F-250 with V-10. Hope this will help you out. As soon as the Mobile 1 0w-20 comes out I will be trying it.

For years the Air Force has done oil sampling for turbine engines to monitor pending component failure. However, for this to be useful you have to know which engine components are being identified by the spike. Otherwise, you will identify pending failure of a component, but you will not know exactly which one it is until it actually quits...
