Yet another Gas mileage question
 

Ok someone try and figure this out, because I am stummped. After all of the improvements I have done. Full tune up, new header, sudo-deck plate mod, new thermostat, cleaned throttle body & adjusted TPS, etc...

I am getting better gas milage in stop and go traffic (city driving on the hi-way), than I am getting when cruising at hi-way speed (AVG 70 mph).

I thought stop and go is supposed to have a negative effect on milage not the opposite? Any thoughts.

It is weird, but check this out.

I always get better gas mileage after a 4WD romp in the woods.

I normally get about 12.5 to 13 MPG in my rig with city/highway driving.
Take into consideration though I'm not geared for the 31" tires, so my mileage is actually a bit better than it comes out on calculator.
And I do check my mileage every fill up.

I filled up yesterday and I got 14.25, the highest I have gotten in months, and it was from going wheelin'.

That is with lots of slow driving up steep hills too.

I can only attest this phenomenon to the fact that the rig is happy getting it's shoes dirty in the woods, and everyone knows a happy rig is a good running rig ;)

yeah Corey, I also am not geared for the 31's on my truck. But is noticeable on the gas guage. If I have a bad traffic week, 24 mi. stop and go traffic, I can go 4 days on a tank. If I have a good week with little to no traffic, I can only go 3 days on a tank.

Stop and go is a pain but I'll take it if it is better on milage. Just wish I could get better hi-way driving milage.

Pirate,
What tranny do you have auto or stick? Dont know if this is a factor with only 31" tires, but I have heard of people with large tires and auto trannys not geting up to high enough rpms to kick the tranny into final over drive. Just a thought...

5 spd w56

Pretty much still stock and I'm getting about 19.1 around town and almost 20 on my Aspen trip which surprised me with climbing the long passes required alot of 4th-5th gear shifting just to maintain 65mph speed.

94 PICK-UP, 3VZE, V6, AT -- I got 17MPG the other day (about 100 miles for one quarter tank). In city drive.

I think a lot of is my driving habits. Normally, I am very slow on take-off and whenever I am approaching a red light, I let it cruise there, sometimes as far as 100 yards away.

I am also a very slow driver. That's why people hate me on the road. If the limit is 40; I'll be doing 40, while the majority of the others are doing 45 with a few crack heads doing 50+.

This helps alot, I think.
