hi im new to this forum and i wanted to ask to make sure, i have a 2003 1500 QC 5.7l 4x4 and im getting 6mpg in the city and about 11 on the interstate. the original engine went kapput and i put in a 2004 durango 5.7l. new plugs, all new gaskets, cleaned throttle body put a cold air intake. it has the 20" rims with falken wildpeak 275/60r20 tires. im not complaining i know its a heavy truck to haul around but i want to see if this is normal gas mileage.
