mpg gone to crap ????
well i have a 99 7.3. the gas gauge has been screwed up for a long time so when i fill up i go by mileage about every 350 miles i fill the tank with 22-23 gal.today i filled up @ 265 miles and put in 24 gal.Ive never put 24 gal in my truck or had such bad mileage.i took it to ford today paid $170 for them to tell me there is nothing wrong!!!!! the last 3-4 fills I've only got about 250-275 out of the tank before the next fill up.I'm pretty sure its a 26 gal tank I'm not driving it any different then i have before,its all stock. any ideas what the hell is going on?
