With off road tyers your mpg will suffer.
Not stock any more, "bashed in front air dam" time for the ARB.

 

Holly shoot, you guys get 1 1/2 times the mileage I get with the same amount of fuel. It's true that mine is driven all week in morning and evening traffic, and week-ends to run errands, but that's still unbelievably different.

 

Darover,
Did you do a induction cleaning on yours? Cleaner in the tank? It`s the little things sometimes that make the big differances. I`m not worried about how many miles per gal I`m getting I just wanted to know how many miles I could get out of a tank of fuel since my fuel gauge doesn`t work right. I have Magnecor wires and the fusion plugs to install, but i`ll wait untill I actually need them.

 

I got the plug wires, the new plugs, sythetics everywhere new O2 sensors....a lift and 31 inch tires(265/70-16) which create a 6% speedo and odoerror, and I'm not a fast driver by any means. Last tank, I got 12 m.p.g

It's true that its 80% morning and evening traffic with the rest highway. but, unless using the heated seats ( mornings are cold up here now)causes bad fuel economy, I can't explain why I went from 14 m.p.g to 12 m.p.g after changing my front O2 sensors with new o.e.m ones.

 

Taller tires should help in fuel economy. New 02 sensors are supposed to help too? Baffeling aint it? Or wait, Aint aint a word is it? LOL

 

No it aint ! I really can't explain it. Unless it has to do with the aftermarket y-pipe that was installed by the previous owner. When dealing with a gasket problem, I had removed the y-pipe, and had found that the entranceseemed to bevery restrictive. Other than that, my O2 sensors are new, so I guess that if the cats were kaput, I'd get a code.

The truck rolls pretty smoothly when driving, therefore I don't think that the brakes are rubbing causing a resistance. And the tires are inflated to 34 psi front and 38 psi rear.

So I really don'tunderstand what could causeother people with the same truckto getup to 4 more miles per gallon.

 

I actually run 28psi in front and 38 in back. When I ran the fronts higher I would get a front end wobble. Sticker on door says to run them at 28 on front. Thats where I`m at. I`d like to get a roof rack so it will make fuel mileage go down. But hey, Its only fuel right??

 

I would guess that your regular station started mixing Ethanol up to 10% about the time you changed the O2's. Just a guess, but it will kill your mpg by 10%

 

With the cra-,, ethanol I lost 22% in town and 9% hwy .

I DO NOT LIKE ETHANOL, LESS OF EVERYTHING
but cost.

 

I was trying to find a link, map, anything that showed ethanol use by gas station is my area, but came up empty.

...anyone know off-hand which gas station companies as a rule use ethanol and which don't?
