Boy, I don't know what happened this weekend, but my mileage was way down. I only got 14-15 mpg driving just under 500 miles.
From the easy one to the worse...Fuel filter/dirty EGR sensor/Plug intake

You probebly got a contaminate refuel or your EGR sensor is maybe dirty, just refuel from place with intensive traffic (Truck stop) check for water in your fuel filter, check your air filter and if this not help then clean the EGR sensor or find someone to do it for you. You got a hell of a truck! The new 6.7L are less reliable so far...And they get lower MPG

Something worth noting on gas mileage: use the right gas.

Our 3.0L V6 Ford Ranger runs just fine on "regular" gas when we're not towing, and filling up with "plus" gas doesn't really change its MPG figures much. Not so when we're towing.

When we tow a trailer and the Ranger has "regular" gas in the tank the engine "pings," or makes a subtle clicking, almost crackling sound when we accelerate or climb up hills. The engine makes that noise because the gas is burning faster than the speed of sound, literally exploding inside the cylinder, instead of burning in a smooth, easy fashion that radiates outward from the spark plug.

Pinging is not good. It leads to incomplete combustion, increased wear on the piston rings and valve seats, deposits on the valves and exhaust manifold that rob the engine of power, increases the vehicles emissions, and delivers less power from each cylinder stroke, reducing gas mileage. All bad things.

When I tow I gas up with "plus" fuel, and the pinging goes away. So my engine is happy, and my gas mileage goes from 15-16 mpg (sometimes worse) to 16-17 mpg (occasionally better).

I really think it is a 2.5L engine. The 2.2L was my 1970 Toyota Crown straight 6!

In 1961 I had a 1959 Triumph Estate Wagon. I drove 60 miles at 50mph on 1.4 Gallons of gas! That works out to 40.1mpg. I don't see where the 'big improvement' in gas mileage is.

Last weekend I confirmed that when towing at 60 MPH I see 15 MPG towing.
