Bone stock '02 F250 5.4 with 285s and horrible MPG. Is it the tires?
Guys,
I've got a 2002 F250 5.4 with 285s on it and it is getting MPG down in the single digits. Is it the tires? Anything else to try? No codes, doesn't smell rich or anything like that.
Anybody make an new y-pipe for this truck? I looked and can't find one? Was thinking about new exhaust from the manifolds back with a new cat and better muffler.

How bad is bad?
I'm at around 13mpg's around town all the time in my 2012 F350 Reg Cab 4x4 with 3.73 gears and 285-70-18 tires. Sometimes its better, others worse. The trucks mpg's never seem to be good on cold start ups combined with cold mornings. It seems as if the computer dumps lots of fuel in the motor to get things warmed up. Once warm, the engine gets better mileage.
My truck came stock with a block heater (yes its a gas 6.2) and I am going to start using it to see if I can get better mpg's with a warmer engine upon start up.
One thing is for sure, turn the traction control off and put the trany in "M" mode and the thing rips. Lots of power on the upper end of the RPM spectrum
Good luck with the 5.4, I've read several threads about ignition coil packs going bad but not throwing codes. You could also have a clogged catalytic converter?

I have gibson dual exhaust, SCT by mike @ 5 star in 87 economy, spark plugs changed under 1000 miles ago, cleaned MAF sensor and 265/75/R16 tires and my average for the entire year has been 11.8 mpg. winter fuel kills my 5.4, ive dropped to 9-10 but hopefully with this tuner that will bump it up some. over the summer commuting to work (about 75% highway) i was at 14 mpg. record has been 18.3 mpg on the highway for 103 miles, cruise control set at 68
