Can someone help me? please.
I'm getting 9 miles to a gallon currently, I checked air filter, spark plugs, mass air sensor, tire inflation, turbos are fine. Truck fires right up, nice smooth idle and it feels fine.
I was getting 17 miles to a gallon but now I'm getting 9, I just don't know what else to check.
Any suggestions?

Stock tires and wheels?
Check engine light on?

How many miles?? Has the alignment been checked?? Is the emergency brake fully released??? Anyone else drive this truck besides you??? Any chance someone could be stealing gas at night??
