Hey guys I'm loving my new 2017 F150 2.7TT. Seems carbon build up is a real issue with this engine per some videos from a Ford Technician on youtube. Just wondering what I can do to keep that engine as clean as possible on the inside. My first oil change was to mobil 1 synthetic but I'm wondering if a different oil would be best for the DI engine. Also 75% of my miles are traveling long distances to work (500-600 miles), wouldn't the full fuel tank runs at interstate speeds help keep carbon at a minimum? Also I already run 93 octane. Thanks.
