Ecoboost carbon buildup

I have an Ecoboost SHO, with twin turbos. Two years old, premium fuel and no problems. On a recent trip to Colorado, I was cruising at 80 on I-25 (Legal in WY), and getting 28.9 mpg, with my wife and luggage for a week in the rockies. Admittedly, 99% of my driving is 70-75 mph, with very little city driving. The only thing(s) done to it have been the Fuel Module recall (no problems but replaced by the dealer as a precaution) and the check of the right front axle, also a recall. Again, no problems. I do change the oil at 5000 mile intervals and use a full Synthetic. Apparently, according to a member on the SHO forum, Ford does not recommend using any cleaner as it can destroy the turbos. With the warranty Ford has on the current engines, I would not be concerned. I did purchase the 7/100 ESP from Ford, just in case.

BMW has been using DI on their cars since 2007 with the 335i with no issues. Now the N54 motors had other issues mainly HPFPs and such but carbon buildup on the intake valves was not one of them.

I must be getting old(er) as I could not find the thread;however, I did find this from a 15 Jun 2011 article in Edmunds Auto Observer, maybe cleaning is a mute point:
"At the Detroit Auto Show in January, Ford was confident enough about its popular 3.5 liter EcoBoost direct-injection V6 to have technicians tear down an example engine that had accumulated the equivalent of 160,000 miles through an intentionally abusive regimen of log dragging, high-speed towing and desert racing. When they opened it up before a live audience, they found some light carbon deposits on the valves and pistons, but not enough to affect performance. In fact, the engine showed a loss of just one horsepower afterwards."
Hope this helps in lieu of not finding the info on cleaning.

That's what I was thinking. To make your engine last you can throw that ecoboost (alleged) better mileage out the window. The F150 owners already complain loudly that the mileage sucks and many wish they would have got the 5.0.

That's probably why you have very little problem. Especially if its a long commute. Unrelated to the engine but still working under the same principle I've seen people almost double mileage warranties on tires with long commutes (50-60 miles on the highway one way)
An extended light load with the engine up to operating temperature is about as ideal as it can get compared to driving around in the stop and go hell that is in the city where people have short commutes.
