Probably one of many posts about Ecoboost oil, but wanting to confirm my thoughts. I purchased a very nice 2014 F150 King Ranch with a 3.5 Ecoboost. The truck has 155k miles on it. It has been serviced fairly religiously every 5k with synthetic oil, and is completely silent at startup and when running. The Ecoboost makes me nervous, but many times you don't hear the good stories and only the bad. What also makes me nervous is I'm getting rid of a Toyota (sedan) to get this Ecoboost . I'm hoping to avoid any major issues with the truck for as long as possible by changing all the fluids again (they were all last done at 100k, along with spark plugs) in the next few months, and then continuing the 5k mile oil change interval. What concerns me is what I am reading about fuel dilution in the 1st gen Ecoboosts. I have fairly short commute to work at only 1.5 miles, and then depending on the day I may or may not make similary short trips between buildings during the day. Outside of work the truck will be driven a little further and have more time to warm up, but not the probably hour or so I would assume it takes to clean up the fuel dilution. It may only get the good hour or more drive once every week or two. So, my plan at this point as we get closer to fall and then winter temps, is to plug the block heater in if the temp is low enough, remote start the truck when getting ready to leave so it has a minute or two to circulate oil (I've never warmed vehicles before, only given a few seconds for oil pressure and then drove away gently while it warms up), then make sure I try and get a good drive on it on a somewhat regular basis and/or consider 3-4k oil intervals depending on how that goes. I am intending to run Quaker State Full Synthetic 5w30 as that's what I've been running in our 5.4 Triton 3v F150, our 2017 Edge 3.5 Duratec, and even our lawn mowers and snow blowers (one oil across the board great simplicity!), and a Motorcraft filter. The truck did just have an oil change but I noticed tonight when looking around that they used a AC Delco filter, so I'll likely do a QSFS oil and motorcraft filter oil change soon to remedy that. My other intentions are looking into getting a catch can as well as doing the1/16 weep hole in the bottom of the intercooler.
