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!

 

umm ya, get a different car!

 

oh and btw, welcome to RF!!!

 

Thanks for the warm welcome, and thanks for the useful information!

I bet removing the entire air filter would help a ton, you cant blow any air through one of those. But something could be sucked right into the engine

 

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.

 

Better mileage? Read the sig

 

Not a whole lot you can do.

hence why i did the hyundai mod lol

its a truck, a 4.0L V6, and a 4x4, heck I'm surprised your gettin around 18.... but yeah let some air out of those tires and do a tune up, and the main thing that will help you is lay off the skinny pedal, thats what helped me!

 

yeah,,, just save your self time and just get another car.

 

lol, atleast we're all on the same page here.

 

I inflate my tires to the max on the sidewall also. Much less rolling resistance when loaded...18 is pretty good, just drive it nice and find long downhill roads.

 

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.

 

get a 3.0. I get 25-26 highway :)

 

^^^you're 2wd also.

 

I don't get that on the hwy!!! Must be different gearing...

 

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. :(

 

my 2.5L mazda got me 27mpg all around

 

holy ****!

 

18MPG holy crap. best ive seen so far on mine is 11

 

ive gotten as high as 22.5 with cruise set at 65 already and i have a 4.0 4x4 lol

 

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.

 

keep the truck it helps the economy by keeping gas haulers in a job.
