I have a 1994 F150 5.0 with 187,000 miles and gas is killing me I only get 12 miles to the gallon and i was wondering if there was any way to make it get better with the job I just started i feel im going to be in trouble with it. So is there any way to get better gas mileage seems my only option is to sell the truck and I don't think i could do that.

 

12 mpg is about average for that truck. As far as mods it would take years to pay those mods off so save yourself the money from the mods and just use that as gas money. Fyi I only get around 12 with my 97 and a 5.4

 

Start with a basic tune up (plugs, wires, cap, rotor, air filter).

Lube, oil and filter. Prefer a good synthetic oil in proper viscosity for engine.

Repack or replace front wheel bearings and seals (if 2WD).

Check front and rear brakes for ANY dragging, repair as necessary.

With the miles you have on the vehicle, I would also check and replace as necessary the O2 sensors and the catalytic converters.

Check tire pressures and keep inflated to maximum inflation pressure.

Check vehicle wheel alignment.

How hard are you accelerating from a dead stop? Is your foot so far in it from a standing start that the intake valves have Athlete's Foot fungus? Or are you keeping up with traffic from a standing start?

Remember, you are driving around 4500 + pounds of steel with the aerodynamics of a brick. F150's and fuel economy just don't mix.

 

is that around town? highway? mixed? my 93 4x4 got about 11 around town with a worn out 5.0. right now i can get 9-13mpg around town depending on how i drive. there are small cheap things you can do like insulating the stock airbox and hoses with a foil face self adhesive foam insulation and throw in something like a K&N drop in filter. advance the timing a few degrees(stock is 10* btdc). do a tune up with autolite copper core plugs, a decent set of wires(i like the napa beldin wires and they are lifetime warrantied) distributor cap and rotor, fuel filter(i prefer wix filters), and using seafoam to clean out the engine. thats about all your gonna be able to do cheap to maximise fuel mileage. as said above thats about the average mpg for these trucks.

 

My daughter was just complaining about the same thing, yet she thru the 36" tires back on her 86 3/4 ton yesterday

I've been getting 16mpg with the 98 4x4 -5.4L, city and highway since the winter before last, after going thru it. Pulling and empty 1900 lb trailer I'm @ 12mpg. Loaded, she gulps it down lol.

 

I was lucky to get 12 to 13 in my 2000 f150 but the swampers dont help much.

 

I get 12-14 combined. Best I ever got was 17 up in Montana doing 80 on the freeway up there..

 

Look at the GMC Sierra ads on this site. They brag about their new 6.6L Duramax getting 680 miles on a tank (36 gal). I get over 700 miles per tank on plain ol' regular gas.

 

I have been reading and seen somethings that you can make your truck run on water just wanting to see what yall think and if know how give me the steps

 

I'm lucky to get 360 miles after one fill up lol. I have never heard of 700 miles from a tank, hell I've never heard of over 400. Yea, larger tanks I guess. I wouldn't want that big of tank in a 1/2 ton anyway.

 

Nope, Super Swampers don't help Mpgs. I traded up a set of those for a credit toward a new set of 44's (Ground Hawgs) way back when.

 

That's normal MPG for the 5.0L F150...

My Dad got the same when he had his.

 

I get about 14 Mpg in my 97' F150. I try to drive sensibly as far as speed and take off from complete stops go. I couldnt imagine selling my truck since its already paid for. Just bye yourself a old gas saver to drive to work in and keep the truck.

 

Save your money, it does not work. Search hydrogen on here, that is what the so-called water gas systems do - they break down water into hydrogen and oxygen. Problem is that it takes more energy to break the bonds than you capture back. You can't defeat laws of physics.

Back toy our mileage question, besides ensuring the truck is running best it can and a light foot, using normal size radial tires and lowering the truck can help some. Keeping air from under the truck with an air dam can also help. But the real reason is that you have an aerodynamic brick and weight, it just takes a certain amount of energy to move. Those pesky physics laws again.....

 

what gears and tires is the OP running??
