I had a 14 3.5 eco and I used full synthetic. I had my oil analyzed many times by blackstone. Their recommendation was 5000 mile oci's due to fuel dilution. If it wasn't for the fuel dilution I would be able to go a lot longer. I understand some here feel everyone should just go off of the trucks computer for changing oil. This would make sense if it weren't for the computer not being able to take into account fuel dilution when it runs your driving habits and conditions through the algorithm. I would recommend working with blackstone to get a baseline of where you want to be on the oci's for YOUR truck. Everyone drives a little different and in different conditions so the only way to really be sure is to test your oil. Good luck

Worst hairday ever...
Use synthetic and change out at 6000 mile intervals if you are afraid of the oil life monitor. You have a turbo which is oil cooled. That in itself puts demands on the oil. Also it was proven long ago that changing oil too often is detrimental to engine wear and life. What are you really saving? If you have any doubt you can draw a sample after a set interval and get an oil analysis done. That will tell exactly what is going on with your engine.

Here we go, again.
What does your manual say? I know it's tough to open and read, but it says use synthetic blend or synthetic. No turbo motor says to use conventional and change it more often. Why on earth would you want to do that? I wouldn't use a synthetic blend, since Mobil 1 can be had for $2/quart with the semi-annual $12/jug rebates and is much better oil.
Changing oil more often than needed does not provide 'peace of mind', just a hole in your wallet and wasting time doing unnecessary oil changes.
However, there is no harm in changing oil more often than recommended and there is no study that says it's bad for your engine.

Going over 5K on a turbo engine is not a very good idea IMO, and since I do my own oil changes, it's cheap insurance. Besides, I run a lot of short trips, so that's harder on the oil. And with the reported oil issues with the variable timing system, rather use full synthetic and 5K-mile oil changes. If I was doing mostly highway travel, then I'd go 6K, but here in super hot TX, and with a lot of short trips, not worth skimping on oil changes. The only detriment is to one's wallet, since I recycle it, but since I'd have to pay more than the oil and filter for an oil analysis, might as well just change it 
. But to each his own.
. But to each his own.I run Mobil one synthetic and change at 5 k. I also run short trips. Pull your dipstick at 5k and see how black and burnt the oil is. It’s just a peace of mind thing for me.

Oil Changes
Dilution seems to be characteristic of the high compression direct injection engines. On our E350 with the M276 direct injection engine.. i notice a whiff of gasoline in the drained oil.. the ford F150 2.7 seems to have the same whiff of gas too. I have tried varying lengths of miles between changes.. after 3k miles you start to smell a little gas in drained oil. 6k its stronger.
