Fuel economy

turbo25 · 07-28-2005, 03:31 PM

I have a 1999 s-10 extended cab v6 4.3 vin x, automatic trans. Wondering how many in town miles and highway miles you guys get per gallon? I currently get about 250-280 miles on a full tank which is a 19.5 gallon tank. That is mostly in town driving.

Thanks

ill get between 220 and 260 to a tank, about 20mpg, and i drive it hard

City driving mileage varies from town to town depending on what the traffic is like when you drive, elevation, if there are hills, and a practicly endless list of varibles.

Your best bet for a fair comparison is talk to someone that you know drives a simular vehicle in your city at around the same time of the day as you.

For example if you talk to someone that has to drive in LA at the rush hour peak they'll be lucky to get 150 miles on a tank.

I have a 02 Crew Cab and I get 17 mpg. Thats in stop and go chicago suburb traffic. And when I cruz long distance I ave 22mpg. I its always been that way from the day I took it off the lot. Even put in a K&N air filter hoping it would change but it didn't . Anything I can to to increase it. I would love to here from you.

free flowing muffler.

Synthetic oil in the transfer case and differentials and the engine.

Syn oil in the engine.

Blazerlt's advice plus tonnu cover if you dont already have one, and from what i hear about 2 or 3 oz of acitone in your gas tank every complete fillup will help, going to go raid the shop tonight, if im thinking correctly, we have a 55gal. drum of the stuff, and if we do, a couple gallons is about to fall off the truck and ill let ya know what my results are with it

I have a cap on the truck already. Still stucks gas. How much of a difference will syn oil make? I wish I knew about that earlier. The truck is getting the rear diff seal replaced right now. I would have told them to put in Syn oil. Truck only has 80K I figured I would go Syn after 100K. I love this truck I have beat it up so many times and only minor repairs. Now that I am thinking about it I probally busted the seal in Canada on some very cool logging roads. I thought I was going to loose the boat I was pulling.

Your O2 sensor is due for replacement.

It could be wearing out.

I got 17.5mpg highway recently in my 89 4x4 with the 4.3. And Dang that front end adds ALOT of drag. There is one big hill around us, all of our other vehicles (2wd, never driven another 4x4 on it) gain about 10 mph down it, and I don't gain anything!

You have a brake dragging.

So drive it around for a little bit, then pull out the ole temputure gun and take some readings?

My '99 Sonoma gets about 320-330 miles to the tank. 4.3L, Automatic, extended cab, stepside, ZQ8 suspension, posi rear end. It's all stock other than a K+N intake system. Driving is pretty much mixed between city and freeway. Running the AC doesn't seem to change the mileage very much. I really don't drive it too hard, but occasionally I open it up to hear the roar from the intake system (which is worth the extra gas).

Yea, see if one disc or drum is hotter than the others.

Damn you guys all get better mileage than me.I'm getting like 10-12 mpg.That's with a 4.3 with about 10,000 mile on it,new O2 sensors,new fuel pump,new plugs and wires,cool air intake.I don't get it?
