I want better gas mileage!
Hey guys i purchased a 94' Ranger 4.0 4x4 Auto last week and i'm itching for some better gas mileage out of the thing. With mostly highway driving its only producing 16-18mpg. I was wondering if theres any tricks to get some better fuel mileage?
I'm considering cutting off both cats and running a straight through pipe so the motor can breathe better. The cats are past the oxygen sensors so I don't think it would throw a code or hurt anything. My exhaust towards the back has a kink in it somehow and that has to be restricting flow as well.
I've filled all 4 tires up to maximum psi so the least amount of surface is on the road to reduce friction as well, but im out of ideas. Are there any proven tricks you guys have figured out with the 4.slows ??
Thanks!

Trucks are built for work , not fuel economy.
For starters you can put on the skinniest tires you can fit and remove the front driveshaft.
Don't cut the cats out , as Rangers come with high-flow cats from the factory. It also won't pass emission inspection without them.
Change plugs and wires yet ?
Change the lube in the crankcase , transmission,transfer case, and differentials ?
Re-pack the front wheel bearings ?
Are you lifted ? That hurts the airflow around it awful.

the most ive gotten out of mine was 18.8. dont expect great mileage out of these. first thing would be a basic tune up. spark plugs, wires, air filter, fuel filter, etc. who knows how old the ones it has now are. i wouldnt bother with the cutting the cats off and be careful with tires that full. I would just keep them at factory spec.

be happy youre getting 18, especially from a truck its age. wear and tear over the years/ miles decrease engine efficiency and hurt mileage so youre lucky. my 93 4.0 5 speed was lucky to put out 13-14 MPG's on a good day. no offense but you should have looked into what these trucks get for mileage before you got one.

Choose the wrong vehicle for mileage. The best I have gotten is 19.4 and that was strictly highway. There really isn't much you can do to get better mileage. Which is why I am currently looking at getting a daily driver and turning the truck into a weekend warrior. Cause this 1000 miles a week is killing me and my poor truck. :(

I once got 30 mpg's on the highway with my 07 2.3 5 speed auto. I'm barely getting 19 mpg in the city just back and forth to work. Thats the limits with such a heavy truck to begin with. Keep it stock and don't haul around everything in it you don't need. 100 extra pounds is one less mpg.
