Well guys according to fuely im getting between 12-15 mpg city, before when i filled up from where the first line is by the F on the fuel gauge I would get between 55-60 mpg (highway) once the needle got right under the first line and between 127-139 mpg (highway) by the second line....Today I filled up and between the first and second line I got 77mpg on the highway no where near what I use to get.
My 02 P5 has 158000 miles, 205/50r15 hancooks all around, a simota CAI, OBX header with header wrap, NGK wires with NGK plugs (ZFR5F-11), new coil packs, a vibrant performance stealth muffler, and an oil catch can between the pcv valve and intake mani. I have no codes, no misfires, no sputters, no hesitations, no fuel smells and no idea where to begin with trying to figure out why my mpg's are so bad so if anyone has any idea where I should begin, I honestly think I have a leak but with no fuel smell its kinda hard to say thats what's going. I did notice that the needle did move quick between the the first two lines which gave me that 77 miles (in my trip meter) but as soon as I hit 80 miles (trip meter) it slowed down drastically. So please guys don't be shy with your input.
