I got mine done at the dealer at 4850K. Yesterday the message came on telling me to change the oil. I have 6900K. What does the message go by? anyalisis? just programed to go off every 7K? Also how to reset the message so it won't show.

I'd recommend doing it again around 10,000 miles considering your oil life monitor is useless now. It needs to be reset to be accurate!

Dealer forgot to reset around 4900 when it was changed.
Was alerted at 7100. I had to reset it so it would remain quiet.
Changed again myself at 9900 and I did reset it so I know it is correct.

I had mine done at 5k. That was 7300 miles ago, and the computer hasn't asked me to change it again. I'm not "making oil", so I'm letting it ride. My advice, based on the advice of many others, is to follow the computer's recommendation except for the first change. Do that one at 5k or even a little less. Make sure you reset the oil life in the computer, and watch the oil level. I check mine about once per week. As long as it's not rising, stick to the computer's recommendation and you will be just fine.

if it does not accurately know the oil condition, how can it give you good advice since different oils wear differently. its pretty much a estimate, and estimates can be good and bad. i would do some oil analysis before i trusted the computer. but thats just me.

This technology isn't new, GM, Honda, and many others have been using it for many years with great results.
Check the tech folder, you'll find stuff like this:
1st post, long time lurker, recently joined as an FTE member. I work for Ford btw and my name is Paul.
The 6.7L is more efficient from a base engine design perspective. Migrating to the CGI block material from grey iron results in much less cylinder bore distortion as well. DPF regeneration impact on oil has also been reduced significantly by using fewer "active" DPF regen cycles (post injection) in favor of "passive" regen.
The end result is far less fuel in oil dilution under most operating conditions. Extended idle and low speed stationary power applications can accelerate fuel in oil percentages over time to some extent. Truck operation at moderate highway speeds will keep this in check.
The oil life monitor/systems programming is designed such that it monitors the engines operating parameters (temp, speed, engine load, frequency of dpf regen events, etc.) and adjust oil change intervals accordingly. Some of our fleet development vehicles such as FP&L have reported >9K miles before the oil monitor activated. Note that these fleet test vehicles, along with the others we have across the country have an oil analysis performed after every oil change in most cases.
During engine development it was determined that DSI (down stream injection or 9th injector) was less desireable for a number of factors for this engine program. Refinement of the active/passive regeneration strategy, eliminating the complexity of having another low pressure fuel system to manage, improved engine efficiency and the cost were just a few of the variables.
My intent is to post from time to time when the opportunity presents itself and learn what I can to help make our products better in the future. Please know that I only frequent FTE once a week or so when workload permits and athough unfortuneately I'm unable to respond to every question or concern on the forum regarding the 6.7L or Super Duty, I will try to provide relevant information when/where I can (such as above) within the guidelines of the company. Typically I've found that hearing direct feedback from multiple owners on a particular topic/thread provides a good overview of what the good the bad and the ugly is.
Thanks for your time, have a great day!

I am not saying its wrong, but until I knew how it tested the oil I would be skecptical of it. I know its been out awhile, and widely used in gas engines. My sister trailblazer has it(talk about a pain in the *** to change oil) and I change it for her.
I would like to know how it estimates the oil life. If its just by the way u drive then all it could be is a computer program, but if it has sensors I'd trust it more. But with a 6.7 engine a 7-9k upgrade I want something I know is accurate. That's why I was saying do some anaylsis, if they come back similar to what computer says, then I would be completly fine trusting it.
Also if it does have sensors to test oil, does it test containination along with shear strenght. Either can lead to advanced engine wear.
