Is this BS? (turbo's, ecoboost, short drives)

You'll notice which is happening to your engine once you change your oil. Strong smell of fuel and oil getting darker quicker than normal. Turbo pressure is simply forcing more (unburnt fuel and carbon from engine combustion) around the piston rings before they have time to warmup and expand giving a better seal against bypass.
The 2.7 eco was given both piston and rings which tolerate much higher pressure from the turbos... pretty much the same level as diesel engines. This is also being added to the newer '17 3.5 eco which is adapting alot from the 2.7 eco.

The issue I see with the ecoboost engines and short drives is carbon build up on the intake valves. Direct injection engines have issues with that. Short drives will not let the engine really get to temp and burn off some of that carbon.
The 2017 3.5 ecoboost has a fix for that carbon issue. The 2017's have 2 injectors per cylinder. The second injector is up stream of the intake valves. That will allow fuel to wash/ clean the intake valves.
Ford stated the second injectors are for inproved cold starts and emissions.... But its a bunch of marketing bull.
The truth is Ford is fixing the issue of intake valve carbon build up thats common to many direct injected engines.
The problem with the twin turbo engines,,,, you can't clean the intake with things like seafoam or other intake/top end cleaners. The junk you free up will destroy the turbos.
Adding a catch can will reduce carbon build up but MAY void your warrenty

Advice, dont always drive like your Granny does. One of the best ways to reduced carbon build up is putting the pedal to the floor ! If you tend to baby your truck try to floor it once in a while like up the freeway ramp. Really can help reduce carbon build up on the valves.
Please note I'm not attacking the ecboost engines. Carbon on the intake valves is an issue with most direct injection engines from ANY make. BMW had some big issues with it and so does VW.

Been around turbo charged vehicles for nearly 30 years, and have owned six vehicles with turbos. Ever since water cooling came about in the early eighties, turbos are a non-issue.
I'd worry more about the transmission than the turbo.
