I am about as confused as a Monkey Screwing a FootBall. I have a 05 F250 with 35's on it. I just got it Sat and I am getting about 10mpg on the HWY and about 7 Mpg in town. CAN SOMEONE HELP ME????????????

 

Whew, wish I could help. I saw on msnbc that we will be paying $4.00/gal in no more than six weeks.

My 07 150 is actually pretty good if on the interstate keeping it under 2000 rpm. On a real cautious trip about 180 miles, I got 21.5. Stop and go around town,mix in a little light towing 15.5 to 17.

M.P.

 

I have a 04' F150 SCAB with 5.4L and 4x4. Highway driving I can get 25-28MPG if I keep it around 65 MPH and keep my foot out of the throttle. There is a slight little enhancement that will give you alittle extra for less money. Try adding Turbo 108 Octane Booster (about 5.25 oz) per tank fill-up or better yet at half tank. The fuels now a days is not even close to the 87 octane that they are supposed to be. You can get the large can of 108 (not the small plastic bottle) at Pepboys, Advanced Auto, Checkers, Murray's Discount Auto for between $7 and $10 unless it is on sale and then you can get it for $5 per can. (the small plastic bottle runs $7 normally)

Also, if you have a Flying J truck stop or Mejiers near you stop in and pick up a bottle of MotorKote. Add the appropriate amount to your Engine Oil (2 oz per quart) and then add it to your trasmission, differentals, transfer case (if you have 4x4) and to your power steering (as suggested on back of bottle). Then drive it for about 20 miles to let it work in. This stuff is compatable with all petrolium lubercants and it can be used with Hydralics, 2-cycle, wet-sunk clutches, Wheel Bearings, greases and such. You can read more about it at www.motorkote.com and even purchase it through thier website. I even use it in $600k tractors and pulling tractors. I have used it for over 15 years on everything from Lawn Mowers, Chainsaws, Mazda B2000 (over 300k miles), Ford Ranger 89 and 96 with bother well over 200k miles, Ford Explorer 2000, Toyota Corolla 06 and 00, Motorcycles (Harley, Kawasaki, Honda) plus all the farm equipment $$$$$.

This stuff is great and it works. Check it out.

What are you talking about open Diff????

 

I've had my 5.4 3.73 F150 SC Lariat for about three months now. I haven't done the math, but the computer says I'm getting 22 mpg on the highway, and around 16 in town. I'm averaging around 18.2, if the computer is right. The truck is bone stock with factory BFGs that I run at 40 psi. Haven't added any snake oils either.

Driving style affect fuel economy a lot. My wife complains that I drive like her grandpa, but when she drives it, the fuel economy drops about 2 mpg. I don't drive like a hypermiler, but I do accelerate slowly and anticipate slow downs. I usually drive around 60 (in the slow lane) on the freeway.

dale,

That's real similar to the results that I get. I added a K&N intake that doesn't really do much more than sound loud when I do have the need to step on it. In some places though driving only 60 mph is almost dangerous(I-95) in Fl.

Open diff= no limited slip. I was wondering where on earth he got a 3.31 gear ratio. The only options I know of are 3.55 and 3.73. If I am correct, all the 3.55 ratio's are open. The 3.73 has open or limited slip. I have a Lariat with a 3.73 open diff. I wish I had a 4.10 limited.

 

Truetrac,
Your definitely right about driving slow in some areas. It's a bit easier in Ohio, because the speed limit for commercial vehicles is 55mph. Most travel 60. I can just tuck into a row of semis and travel across the state without being run over. But even where the speed limit is 70+ I usually don't have any problem as long as I stick to the slow lane. The best part is I can set the cruise at 60 and rarely have to slow down or speed up to pass.

I used to drive 5-10 mph over the limit, and was always running late or in a hurry. After years of radar detectors, white knuckles, and looking two miles ahead for the SHP, I said "WTF", and started leaving a few minutes earlier. I've found it to be much more relaxing, easier on fuel and brakes, and the net result is a 60 mile drive only takes 8 minutes longer. No big deal. Maybe I'm just gettng old?

BTW, I regularly get 42 mpg in my wifes VW Passat 1.8L gas 5 spd. using this technique. Sure wish I could have gotten a manual in the Lariat . . .
