I have a 96 4wd club cab. 3.9 engine. I'm only getting about 12 milles per gallon around town and 14 highway. At $2.50 a gallon its starting to sting. Anyone have a similar truck for a comparison. I'm wondering if the previous owner replaced the computer chip. Anyone know what the factory chip is or an alternate that would be more fuel savy?

 

I have a 92 and I only get 10mpg with the 360 and I fill up less than when I had the 3.9, so having that said. You are doing better than me.

 

if yours is like mine it is running very rich causeing the 12mpg check your 0/2, timing and , thermostat, things like that

 

I dunno, runs fine and everything is new, Its a 360 and I have a lead foot, so I'm not complainin too much. LOL

 

i got a 92 3.9l 4x4 and this thing drinks so much gas .. im not sure on the milage but im lucky to hit 400 kms on a tank which costs about 70 to fill but im assuming im getting no mor ethen 15 ish on highway dunnno what the avg is im gonna change som eparts i think .. would the 318 be better on gas ?

 

My 360 is about the same if not a little better, It takes less effort for a V8 to get the truck rolling, so unless you have your foot in it all the time. It shouldnt require you to press the pedal as far. Granted you have two more cylindars using fuel, but thats two more making more power at less RPM's too.

 

ya i think ill probably start looking for a good v8 ..
or would it be better to go to a dealer and get a crate engine or whatever brand new 318 magnum still exist im assuming :P

 

Not from the dealer. Too expensive.

 

4x4 with a 3.9 thats alot off weight being 4x4. could be better but not by much.

 

i have a 92 3.9 2WD and i get about 14mpg in city and if i run all highway i can get up to 17mpg. the only thing i added was a K&N drop in filter. i think i could do better but the engine is not in peak shape. if your looking to increase fuel economy, you might want to look into mods such as cold air kits and computer chips. they can help alot, and also give more power... thats just my 2 cents.
