Here is a fact, there are over 500,000 Eco-Boost powered F150's on the road. And I guarantee you the majority of owners are using the OLM (which for most will give you ~7.5K-10k OCI's depending on your driving style). And most are using Motorcraft semi-synthetic oil and Motorcraft filters.
Based on what I have looked into and conversations with a few Ford mechanics who work on these, here is what I have learned.
The engine was designed for 5w-20 and originally spec'd with that. Some smaller Eco-Boost engines still spec 5w-20. The fuel dilution is well documented, and the recommendation of 5w-30 takes this into account. I have yet to see a UOA with fuel dilution that shows any abnormal wear. Under normal driving conditions you should be able to follow the OLM with the spec'd oil and filter (Motorcraft). If you wanted to play it conservative, you could run 5k OCI's. Running 5w-30 PUP, M1, Castrol Edge, RP, Synpower or even full synthetic Motorcraft is a step up in oil. I would follow the OLM using a full synthetic, again the fuel dilution is taken into account. Using 0w-40 oil would provide even more buffer for the fuel dilution, but it is not the spec'd oil. This is not an automatic warranty dis-qualifier, but it could be an issue if you have any (unlikely) engine issues.
You also are not required by warranty to use the Motorcraft filters. They are generally good, but a few have shown up on BITOG with the tears that Purolator products have seen. You can use Wix, Fram, M1, RP, Amsoil filters with no harm and no warranty issues as alternatives.
If you plan on towing I would highly recommend using premium fuel to get added performance (I've been told somewhere between 20 and 40 hp gain) and less fuel dilution (Allegedly, I haven't tested this. But I can feel the increase in power with premium).
I am currently running 5w-30 Castrol Edge and the engine is quiet and runs great. There is a faint fuel smell in my oil but no more than my Wife's non-turbo GDI Ford Focus. I plan on running this change at least 5k to clean out whatever was in it before. Then I will switch to Castrol Edge (German Castrol) 0w-40 and plan on using the OLM. I have three co-workers with F150 Eco-Boost and they are either changing at 5k with the local dealer's bulk Valvoline or using the OLM with Motorcraft Semi-Synthetic. They all love their trucks and have had no problems. Their experiences were part of what got me to look at a Ford Eco-Boost.
Enjoy your F150 and don't spend too much time reading about all the modifications that are "required" to keep it running.
Thanks for all the info. I have a buddy that uses 5w-30 Redline oil in his EcoBoost. His reasoning is high HTHS & VI numbers he says is great for a turbo DI engine. But I believe Redline isn't API approved. So I'm gonna stick with the Mobile or PUP for warranty reasons, even though looking at the Redline specs it's a pretty amazing looking oil.
