Lift Mpg?

Ok so i have a 98 ranger with the 3.0 and i put a 3 in body lift and a 4 in suspension on it. I am currently running 35in toyo mts on it. I haven tracked the gas mileage on it so I was wondering what other people with the same lift and engine are getting?

Also i am not really sure how to track the mileage?

And what mods have people used that increase the mileage?

I am thinking about selling the thing because of the amount I spend on gas, but I love the truck so much so any info would be great.

I've got an 04 with the 4.0, 3" body lift and 33x10.5 A/T's. With 4:10 gears and a custom tune I'm getting 19-21 mpg.

Changing your gears and a adding a tuner should do alot for your mileage.

not to mention that changing gears will do A LOT to extend your transmission life...

1) Fill up and reset odometer
2) Drive for a while
3) Fill up

Divide odometer reading by the amount of gas you put in to refill it.

If he has not reset his speedometer/odometer to match his tire size, that is inaccurate... there are a few more variables to add into the equation.

Hey not to steal the thread, I have 35's on mine, stuff isn't reset, what math do I do to get it to where I can divide my stuff successfully and see my mileagE?

To get the calibrated mileage, take:


Current tire height
Original tire height

X

Miles on odometer since last fill-up
Gallons to fill-up

= Calibrated Mpgs



Oh, and I get just shy of 18mpg around town 3.0 5spd auto 4.10's 33's, 9" of lift, exhaust, intake, underdrive pullies, screamin' demon coil pack (plugs gapped to .065").

Explain to me how raising the truck is going to change the fuel mileage.

uhmmmm more rolling mass...
more needed to get going and keep it going.... gotta give it more to go up hills..

and normally lifting=regearing which means your gonna be turning more RPMs on the highway

Bigger tires = more rotating mass your engine has to push causing decrease in mileage.

more wind resistance. As your truck is made to have air go over it not under it and lifting it allows air under the truck.

3" body, 4" suspension and 35" tires. The tires should have helped on fuel mileage. Lower fuel mileage=heavy foot.

i've heard they are SUPPOSED to help on the highway.. to keep you going? idk my gas mileage still sucks, but around town there is no way that theory can be right in anyyyy way
if that were the case i would dump the bed and fenders and run 38s

So your saying if you go to a higher gear or bigger tires so the engine runs slower then your gas mileage will be less.

Man, you must be on some REAL GOOD grass or crack. That goes against all the known ways to increase fuel mileage. You ALWAYS make the engine run slower at a given speed to increase fuel mileage.

And, get real, at highway speeds having the truck 3 or 4 inches higher is NOT going to increase the aerodynamic drag on it that much.

Now, if your running around 100+mph then it will affect the aerodynamics but at that point your flat on the floor and fuel mileage is not real important right then. Keeping your *** alive is much more important.

Thanks, I did that and I got about 17-18 miles to a gallon...Im 4:56's 35's 3.0 auto...does this sound right? It sounds high to me. I did 35/28 = 1.25 then I had 195 miles / 14 gallons and then multiplied it and got 17.xxxx

what the FCUKKKK?!

steeper gears.. as in 4.88 or 5.13s up from 3.73 or 4.10? your rpms WILL be higher on the highway... whoa. go learn something.. 99% of the people on here know that ****

and once your rolling sure, bigger tires MAY help, but once you have to accelerate or go up a hill, your engine may be at a lower speed BUT its working harder aka more gas gets guzzled..

99Ranger, a higher gear is going from a 4.10 to a 3.73. That's called gearing it higher.

Going to a lower gear is going from a 3.73 to a 4.10. That's called gearing it lower.

You've kind of got it backwards there boy. Yes, going to a lower ratio rear end will increase the rpm's.

Back in the day putting in taller gears meant you went from say a 4.10 to a 3.73 and putting in shorter gears meant going from a 3.73 to a 4.10. Terminologies change from generation to generation, but going to a higher gear or a lower gear don't ever change.

By the way he didn't change rear ends, he raised the trk and put bigger tires on it. In the long run putting bigger tires on WILL give better fuel mileage if you drive for fuel mileage. If you lead foot all the time anything you do won't help the fuel mileage.

Go learn something huh, well I've been working on trucks and cars since 1957 and spent 17 years as a diesel mechanic with Cummins Diesel on road trucks and 17 years as a machinist in a job shop. I bet you aren't even 20 years old yet.

edit: Well, well, your were born 8/14/88 according to your profile, just a little under 20, pretty good guess for an old gezzer huh. I was born 8/8/41. If you learned anything in school figure my age. It looks like I have a lot more years experience of working on these damn things than you have.

BTW, go change your diaper, you stink.
