Sorry guys but for those of us who don't know what all of those acronyms mean can y'all tell us; on another note what can I do to my 2003 stock 4X2 5.9 cummins diesel with auto tranny to make it get over 15 mph (miles per gallon)in town and 17 on the road

My 03 has 180,000 miles on it and I bought it used last year my mileage is at about 14.5 mpg so any ideas on helping out the mpg; should I have the injectors checked and the valves checked first also when changing the fuel filter it is hard to crank up could the line pump be getting weak, any and all ideas will help

I use Wix and was told by my local parts man that the Wix is the only filter other than oem that doesn't void warranty
