I have done been driving almost 600 miles and I have an average of 16.1 MPG. My current tank has an MPG of 13.9 MPG with 118 miles. Am I crazy or is this horrible economy. My 2018 2.7 always hovered around 20 MPG and I am driving the same.

I will pass on some information my grandfather gave me when I was first married many many moons ago. "Never check your MPG or how much your wife spends while shopping, both will piss you off and there is almost nothing you can do to make either of them better."

Average 22 mpgs mixed on my stock FX4 suspension and stock STX 20" wheels. Been hovering just about 21 mpgs with a 2" level and custom offroad 20s and more rugged ATs.

Well I think my MPG issues were resolved with the O2 sensor replacement. I was able to get 23 mpg over mixed highway driving. I found once I started going over 70 mph it began to drop. 65-68 it kept going up.

Yeah O2 sensor issues will usually make a vehicle dump extra fuel to run rich as a safety measure which will give you horrible MPGs
