Hello all!
I just bought a new to me 2013 F-150 XLT Ecoboost with about 134.200 miles on it. It was well taken care of as far as I can tell, as the previous owner was running synthetic oil and everything was pretty clean except the air cleaner. That surprised me as there was paperwork in the vehicle for a dealership oil change from June of 22 with everything in the inspection sheet marked as good. I would have expected something like that from a Jiffy Lube. At any rate, after reading the great debate about catch cans, I pulled the throttle body and found it to be much cleaner than I expected. With a new air cleaner and cleaned-up throttle body, I took it on the road for a 2,000 mile highway trip expecting to see this 20mpg-22mpg gas mileage being hyped for the Ecoboost. Driving open Western US highways with 80 mph speed limit I got no better than 15mpg for the trip. I admit I do push 80pmh - 85mph where I can get away with it, but most of the trip i had the vehicle on cruise control for long stretches.. Still I was getting 14 mpg to 15 mpg which I used to get with a 2007 Cadillac Escalade 6.2 liter V8 under the same driving conditions. When I got home, I changed the spark plugs so I can monitor many miles they will accrue, even though I was not having any issues with rough idle or misfires. The plugs that were in it appeared to be the originals but were all clean with no oil or carbon. So my question is, what are you Ecoboost owners seeing in real MPG for the series (1) engine? Am I missing some fuel/air issue that can improve the mileage I am getting? What can a person reasonably expect for mileage out of this engine under the conditions I described. I know the obvious solution is to slow down, but I grew up in Montana back in the day of the "reasonable and prudent" speed limit and I never got over it.
Thanks for any help on this.
