why is the millage on my 5.7 hemi going down
I have 109,000 miles on my durango and the millage is getting worse on a vehicle that already gets poor millage. I recently replaced the EGR valve and the plugs. any ideas?
Air filter ok? Driving over about 62 mph really hurts my mileage in my 2007 hemi 1500. I try to stay off interstate or if I have to run it try to keep speed down. Other drivers might not like it to much but if I run 70+ you can almost watch the gas needle drop.

thanks mark, yes I have a k&n filter,could need cleaning. I typically was getting 19 to 22 miles/gal on the freeway at 65 mph. recently I can barely get 18 and the in town millage is down around 2 miles/gal also.based on what the computer is telling me. the only thing I am noticing is the exhaust is getting louder probably a result of the baffles on the inside of the muffler and resonator rotting out.
Cleaning the air filter will probably help some.
Common mistake..don't worry. We are not Mark That's to click if you think the post is helpful
