i have a '98 f150 4x2 w/4.6 engine & get 18 mpg, 10 mpg towing 4300 lb tt. i am considering upgrading to a diesel 4x4 but am concerned about the fuel consumption.
could some diesel owners post their mpg. thanks for your help.

 

I've read that the new 6.0 is rated at 18city/24hwy.

Do you tow most of the time? Then the $5,000 upgrade and cost of a new truck might be worth it.

 

I have a 6.0L PSD diesel with the 5x auto. Currently the trip computer says that I'm getting 15 in the city and about 18 on the freeway. I'm told to expect it to raise as the motor gets broken in. The truck has close to 2k on it, That puts it right in with my 2001 E-150. I did pull a camper with the E-150 last summer and the mileage was halved.

 

Fantastic fuel mileage, read signature, P.S. I tow a 10K trailer up in the hill country and it doesn't downshift out of 4th, or slip the convertor...

 

got a 2002 2wd with about 15k and average around 18-22 depending on the type of drivivng.during pulling it drops to around 17 but it still isnt broke in yet.

 

McQueen--Welcome aboard!!! this is one of the best websites out there...

I got best fuel economy between 10k and 15k...

 

After 25k, I was getting 18MPG unloaded. With a 6500# trailer, I was getting about 12MPG. That was with the 7.3. Dunno what I'm gonna get with this derned GMC.

 

Hello,

'02 w/7.3 and 3.73, 15-17mpg all day long. Towing a 9k# 5er aprox 12mpg.
