New to the site and couldnt find any threads that talked about mileage this bad. Also new to my 2011 f150 ecoboost 3.5l v6 Lariat Screw without any modifications (that I know of) and with a bed cover. Filled up on Thursday night, drove about 4 hours of city, and about an hour highway total over the weekend and its now Sunday and I'm at a 1/4 tank. Currently getting 12.0 mpg city with a very light foot. Recently took a 600 mile road trip and got about 14.8 mpg, but I cruised at 85 and I hear mpg drops off over 70 so Im not too worried about that. I'm going easy on the pedal and Im getting maybe 1 mpg more than when I normally drive it. In stop and go traffic the truck also shifts at really low rpms. Driving through town I never get above 2k rpms but im almost always in 4-6 gear. Coming off a light I'll hit 6th by 40 mph or so but when i have to slow down i stay in a higher gear and it sounds like the truck is bogging down. Could the rpms cause bad mileage? Am I wrong to think it just doesnt sound or feel right? I live in florida. Its been 50-70 this weekend and I drive by myself or with one person. Havent driven over 70 this weekend and havent hauled anything.
