Thread: Ecoboost gas milage

Got a 2011 fx4 crew cab with a Ecoboost getting 15.5 mpg. I expected more. It's also going through a long winter here in VT. I have to climb a short hill everyday to work. I use cruise whenever possible and the truck is totally stock. Anyone have any suggestions?

Yeah, and 15.5 is better than my current 11mpg. And that's with gas at $4.32 a gallon here. Is your way to work mostly city or mostly highway?

I'm getting about 20.5 mpg from my 2011 fx4 crew ecoboost. I've been trying premium, regular gets me about 17 mpg. Only thing I have is cold air.

Just rolled over 6k. I have herd I have to wait for it to break in but I didn't expect it to get worse. Anyone herd of extreme fuel treatment? The trip to work is mostly highway at 50 mph and a short slow down at 35 to go through a village which I mostly coast through... Thanks for your input folks it defiantly appreciated!!!

Ok, your mileage is a little low for that style of driving, but yes the engine has to be broken in first, then you will see an increase in mpg's. Also, like what Raptor said, winter blend gets you worse mileage. I've lost about 2mpg's since the switch. After they switch to summer blend your mileage will probably go up to 17.5mpg or so, and it should increase more as your engine is broken in. So don't worry too much as of now. Wait until the switch in blends and if you don't see an increase in mileage tell us.

You guys get winter blends in FL and CA?

Yup, I believe it's a nationwide thing, has to do with Federal Emissions Laws.

I hate winter gas


And salt. Hate salt
