I have a 94 302 4X4 and I did the basic tune up spark plugs, wires distrubitor cap anyone know a way to get more mpg's as mine is ****ty.Iwas thinking about doing exhaust and a cold air intake any thoughts?

 

Yea exhaust and maybe some headers, also i got rid of the mechanical fan and put one from a 94 cougar with a temp sensor in mine, and also try an under drive pully kit

 

Yeah i got an idea: Quit HaulnAss!!! LOL!!

 

Better intake and better flowing exhaust, underdrive pulleys, a guy online here said he gained 4 mpg by putting in a new thermostat rated at 165, an electric fan would help too. See what Jet chips has for your year.

 

Oh and maybe check out your O2 sensors, and find the thread on here about advancing your timing

 

you could always put a honda k20 vtec motor in haha, i thought it was kinda expected for bad mpgs, hell im getting 11 or 12 i think. whats typical for a 5.0 anyways

 

did you ever try sea foam in your gas

 

11 or 12 is typical gas for the 5.0

 

!8/23 MPG's (when I drive specifically for maximum miles) on my 87' 302 auto trans. w/87 octane. Balanced compression output, stock Motorcraft plugs, sidegapped to.054. 60K coil (48K would have been fine, but it was a packaged deal), brass cap & rotor, MSD Superconductor wires, 16BTDC base timing. K & N drop in air filter, Synthetic fluids, 60% distilled/ 40% antifreeze, 180 F thermostat, wax once a month weather it needs it or not. Lucas Injector cleaner every 5 tanks, Seafoam through the air intake manifold prior to oil changes. 11 MPG is what you get if the ECU isn't entering closed loop function, or some combination of maladies. Or mods made w/o MPG's a concern. I've just about talked myself into some aluminum underdrive pullys. Not sure what they'll do to MPG's. I could spare 1 or 2 mpg's if I the performance increase is worth it.

 

Hey i keep seeing people talk about that seafoam stuff but what is it and what do you do with it, ive seen it in stores but never tried it or picked up the can? and what package deal did you get?
