I've noticed recently that I'm getting 13 MPG whereas I was getting 16-18MPG last month. My tire pressure is 37lbs all around. I don't feel a loss of power, knocking, or sputtering. It's a 2008 with 165K highway miles 1 owner.
Is it Tune up time? I know the oil is due in about 500 miles. I just don't know why all of a sudden it starts sucking the fuel. Air Conditioning?
My truck is an 11 ext and I drive it back and forth to New Orleans every month. It's a 2500 mile round trip and if I try to to make two trips on the oil my mileage goes way down. From 22 down to 17. I would bet your Low on oil. It's 25 bucks. Change it.
Spark plugs don't last forever either. Another cheap 20 minute job.
