I don't so much disagree with changing more often but there is too often if only because of the waste.
with a full synthetic flavor run at least 5K between changes. And to put perspective on that I run an approximate 7200 mile oil change interval with my 2.7L.

Well that's interesting. I have an Acura (Honda) with 200,000 miles on it and it gets it's oil changed when the when the maintenance minder says so, that's every 10,000 miles. No timing chain stretch. Honda got rid of fixed service intervals (7,500 miles) many years ago, mines is 10 years old
According to some you should change your oil before your trip. Change it again when you get there. Then when you get back home change it again. You cannot change it too much. As a matter of fact you should've changed the oil on the dealer's lot before you brought it home.
Ford engineers spent lots of time and money developing the engines and transmissions in our trucks. They designed, engineered, tested, and built them from the ground up. They may know what they're talking about when they say change the oil when the IOLM tells you too.
At the end of the day it's your money and time and you should do what you feel most comfortable with.

At my next change (2.7 @ 33,000 miles) I’m going to have Blackstone analyze mine. I run the recommended Motorcraft semi syn with a Motorcraft filter and the oil will have about 8000 miles on it. I found it interesting on their site that Blackstone won’t recommend an oil but did note that everyone there generally used conventional oil.

most of blackstones customer base are fleet owners, airplane owners and boat owners. Yes really. the airplane owners that have their toy planes with Lycoming engines are not recommended to use a synthetic oil but the shell ________ that has the lycoming spec on it. Since the bottle isn't labeled as a synthetic - most consider it conventional. They guy that has the inboard mercrusier motor on his ski boat - uses whatever the dock MX people put in or whatever - marine oils typically don't say synthetic on the label either.
The other big group of customers are fleet owners that run on road semi-trucks - using Rotella D or some flavor there of - also not labeled synthetic.
SO I could see how their evidence might skew aside.

When i had my eco i had my oil analyzed and blackstone said due to fuel dilution they recommend 5000 mile oci. I always reccomend getting an oil analysis done to see where you are at for your trucks oci's.
i now have a 5.0 and i am on a 7000 mile oci at the recommendation of balckstone. If it comes back good i will push it out a little farther. But thats my truck and the way i drive and use it, not everyone else's. I run penzoil ultra platinum. Some say its hard to find but i buy it off walmart.com with free shipping for $24.95/5quarts.
whatever you decide do not follow the olm for your oil changes. It does not take into account fuel dilution. Fuel dilution just kills the oil in the ecos.

the way a person drives and uses their truck will make a difference in what will work for long term maintenance. For the average person that drives 10 to 15 thousand per year coupled with their driving style and powetrain the olm may or may not work for them. Driving a lot of miles in a short period of time and following the olm might be okay. Any way you slice it get an oil analysis done and know for sure.

I agree with Santiago. By the way, how many guys here know how to tell when their engine has completed it's break in? Full Synthetic oil will prolong the break in miles. The stuff is just that slick. So for what its worth, I recommend using the semi synthetic or dino oil for the first two the three oil changes. (3K intervals). I monitor my mileage closely and when I see it start to climb from what it starts out at when new I know the rings have started really sealing. At that point I switch to Full Synthetic exclusively. It works for me.

As to synthetic being lower friction than conventional I wouldn't bet a whole lot on that with oils meeting GF5 + the upcoming GF6.
As to Synthetic Blends most Conventional Oils are a Group II / III Blend or possibly a Group II+ Oil (Can't legally call it blend although basestock quality may exceed some blends) whether it's marketed as a Blend or not. Can't hardly meet the standards today without it
The margin between most conventionals and "synthetics" today is very thin.
The primary advantage of most Premium Synthetics today is they are formulated for longer drains. If you are not going to take advantage of that you are not getting much extra for your buck.
