In a 2005 F150 5.4 liter engine, 5500 miles with a middle Ga. climate. It seems to be getting terrible gas mileage ( 12-13 mpg) with the MC 5-20. I am not a driver with a lead foot so I know that I am not abusing the engine as far as gas mileage goes. Any and all help with this would be greatly appreciated.
What would you recommend?

OIL probably not responsible for low MPG. Did you get better mileage with a different oil or something?
Think winter fuel.

huh???
I think he meant oil is not responsible for MPG. You have a typical ford truck MPG. You can't really do much better. Take it to your dealer and have it checked out. Even though you don't have a lead foot, your driving habits may not be conductive to good milage. Pumping the pedal, not driving smoothly and steady. Coasting into stop signs and lights. May not apply to you, but a lot of people who consider themselves smooth drivers are anything but.
Sorry yeah - what a typo!
Fixed, thanks Fred0803.
Bottom line - look elsewhere besides oil.

BUDSHAD,
Here in the Northeast the refineries blend gasoline and diesel fuel differently (leaner)during winter months causing between a 10 to 15 percent penalty in fuel mileage. I get 22.5 MPG in the summer and cannot break 20 MPG in the colder months, in the MACK I get 5.65 in the summer and 4.75 in the winter. This is probably what PABLO meant. I don't know if they have these cold weather blending rules in your area, but if they do and you increase your figures by 10% you would be right where you s/b.

I believe the oil is the correct viscosity. However, I am thinking the 12/13 mpg is environmentally and behavioral related.
So for example I have a 1996 Toyota Landcruiser that is EPA rated from 13-15 mpg. So the real world range can be from 11-18 mpg.
The recommended and used viscosity is 5w30.

Everyone I know that owns a full-sized pickup from the Big-3 complains about gas mileage.
Interesting about the lower mileage with winter fuels. Combine that with ethanol and I guess it could be even worse. I remember when my dad gave me his old Lincoln Town Car with a 5 litre it only got 12 mpg.
I would say a combination of the winter blend fuel and the possibility that the motor is not completely broken in yet at only 5500 miles. Some vehicles need as much as 10k miles of break in before they see an improvement in fuel milage.

Budshad has the 5.4 V8. He probably would have gotten better mileage with the 4.6 V8 or the six banger. Of course the current F150 is a pretty heavy truck (IIRC about 4400 pounds) and that will toll on the fuel mileage too.

are these highway miles?
i guess i wouldn't be blaming the oil just yet, especially with all the different qualities of gas out there and doing simply things like properly inflating your tires.

My 2000 Silverado 4x4 Ext Cab (which weighs 4800 lbs(I've had it weighed
4.8 lt V-8 with 5 speed.
Worst it's ever gotten was 16 when I towed a U-haul car transport with a 1967 Willys CJ-5 jeep on it from Apply Valley, CA to SLC Utah. Spent most of the time in 4th gear going 60 mph just to be safe. (U-haul takes so much care of their trailers
My 1996 Chev c1500 2wheel drive 4.3 V-6 would get 24-26 all day long..
My 1994 F150 2 wheel drive 351 v-8 would do max 16 mpg.
My 1990 F150 2 wheel drive 302 V-8 would get 15mpg.
I've always found that Fords don't get good MPG over Chev.
Never owned a Dodge truck or had one in the family that is gas powered so can not comment...
For the orginal poster, I'd run 5w30 dino, change it every 4-5k miles or 6months and drive super light on the go pedal.
Also, it may get a little better once you get 10k miles on the truck.
Take care, Bill
PS: Trip sevens is correct, I do wish my truck got 30 mpg!

I was getting 15.5 in town with my 2000 Chevy Silverado with the 5.3L auto.
Got 20-21.5 on the highway.

Yeah, my 2004 GMC Sierra has the 5.3L with 4-speed auto, 3.73 gears, and 4WD. I get 18-19 on the hwy at 60-65, and 15 in town and pulling boat.
I had a 2001 GMC Sierra 4.8L with the 4-speed auto, 3.73, and 2WD. It got 21-23 hwy at 60-65, and 17 in town.
I would have that checked. I'v heard Ford's got worse gas milage than GM, but 13-15 is just crazy. GM 2500HD with the Vortec 8100 8.1L Big Block V8 get 12 mpg, so something isn't cool, I would think anyway.

Does Georgia even get 'Winter' gas ??
If you only got 5500 miles on your truck, it will only get better as you put more miles on it.
My friend has a new Mini Cooper S and was also unhappy with its poor gas mileage when new.

It is not a truck, but
My 5300 pound Toyota 4Runner V6 gets 23 MPG combined city and hiway (EPA rated at 17/21).

Hello, Budshad. If MPG is an issue, why did you buy a petrol car? The same car with a turbodiesel uses 20-30% less fuel. If you aren't satisfied with the output from the engine of a turbodiesel, it is easy to "chip" it and then you are increasing MPG further. A modern turbodiesel is more economic than a hybrid(only because hybrids don't use dieselengines), and faster than a petrol-engine in practical use, because of the higher torque.
