hey every one my first post.... just got my 06 psd supercab 4x4 lariat.. love it this truck rocks, bbut my mileage on my lie-o-meter is only at 13.5? i only have 350 miles is that why?maybe its winter fuel? help!!

 

Welcome to my world. I would try calculating mpg by hand.....otherwise, if I got 13.5 mpg from my 05, I would be doing backflips. I get no better than 11mpg not towing.

 

Cold weather will impact gas mileage. Congrats on new truck.

 

I started out getting 15/19.5 I now have 12,000 miles on my '05 cc sb kr and am lucky to get 13.5/16.5. Bad news is that is seems to continue to get worse.

 

maybe ill keep my mouth shut then? it started at 8.0 and slowly has worked its way up, just expected more.. guess with mileage on o.d. increasing i should? hope to see the mileage increase.... dealer told me to do first oil change at 5,000, i was thinking maybe earlier???

 

5,000 sounds too late to me also. I did my first change at 2,500.
I followed the break in instructions i found on this site- at first I was so happy with my mileage and bragged about getting 19.8 on a trip to my buddy who has an '04 cummins. I am to ashamed to tell him that my mileage is getting worse.

 

I think the fuel this winter must be poor qualty....I went from 16 to 12 on short trips this winter....I have resentily started using Deisel Kleen and am back to 15+ now

 

try using an additive to retain some mpg. Stanadyne has done well for me. Dont fell to bad it is not just psd'd a friend with a 04.5 cummins gets only 9mpg but he does have 36" tires. Still 9 aint good no matter what especially at 2.40 a gallon

 

I am getting 15.5-16 City and about 19-20 Interstate on my 06 w/ 3K miles on it.......

 

I've got a 05 250 King Ranch with 12,880 miles. Around the city I drive as light as possible, (many 30 mph zones with tight enforcement) and am getting 11-12.9. Highway under 75 gets 17.5-19. Towing with 3 horse trailer with 2 horses gets 11.9 to 14.

 

Your engine needs to break in. You're bearings need to break in... Lots of moving parts to get acquainted.

Gas mileage goes up as the truck gets broken in. Some people say they get their best mileage after 30,000 miles+

It'll come... Don't worry.

 

A lot of other factors play into the mileage. Your driving habits, what truck are you driving, quality of fuel, etc....

 

I have an 04 F250 CC 4x4 with 21000. I'm not happy at all with my mileage. It was 14.2 mpg until my dealer reprogrammed the computer. Then it dropped to 13. I've been back to the dealer several times because of this, and all they say is Ford won't stand behind any kind of mpg requirements on a diesel.

I'm looking into a Edge juice platinum with attitude to try and help with some of the mileage issues. A lot of money to spend to only get 2 more mph!

 

I have 9K miles on my 05 F250 Lariat 4x4, I get 14/16 around the city using #2 diesel. When I use Winter blend I only get 12-13 (even tho they say it increases mpg) Now towing my 30ft 5th wheel, I only get 10/11mpg. Im interested to see how this baby gonna handle going throught the Rocky mountains this summer.

I change my oil every 3k miles no matter what. I believe this is the key for longevity for a diesel. My last diesel was a 7.3 an I had 225K before I sold it and its out there still running.

 

I have a 2005 F250 FX4 6.0 with 44k miles on the clock and when the wife drives she is getting about 20.5 mpg. That is based on 100 miles a day of which 90 are highway miles at 65mph. Your mileage will get better as the engine breaks in. I have found that how you drive away from stop signs and traffic lights will greatly impact your fuel economy. Also keep in mind that these diesels don't break in until 30k or more.
