10mpg

[sonofmayhem]

UPDATE

second fill was 11.185 gallons premium gas. on the first fill,11.438, i got 185 miles. its about 16-17mpg so thats the norm. my tires were LOWWWWW. my passenger side tire was 15psi and the rest were 32psi and they are supposed to be 50psi, i do some haulin here and there.

Sounds like you're good to go, you're getting pretty good gas milage.

[uradyke15]

take a reading of the milage when you are filling up. Drive until you decide to fill up again and bring a calculator to the gas station. When you fill up this time, first look at your speedometer and see how many miles you have driven since your last fill up. Once youve finished filling up and after the automatic shutoff is completed, look at how many gallons you have put in. Take the number of miles you have driven since last fill-up and divide that number by how many gallons it took to fill up your tank. Ths should give you a fairly accurate reading of your mpg.

People already went over how to get your mpg.

I just previewed this and its long as hell but whatever...



Since you mentioned 50psi, which is a ridiculous amount or air for an unloaded yota, Ill let you in on THE trick to get the most out of your tires.

50psi sounds like your running an oversize or hi traction tire. Like it will say on the sidewall "max load 2250lbs at 50psi". Since these are not factory recommended tires you really cant go by what psi the manufacturer recommends because it will almost always be too much - too much air in a tire makes it ride unnecessarily harsh, wear the center of the tread and reduces traction due to only the center tread contacting the ground. A tire is also not designed to be run at max psi unless you are running close to its max load all the time.

This procedure is for oversize or hi traction (mud terrain) tires ONLY because usually these tires are much stronger, thicker and designed to carry much more weight than the standard size tire that is recommended for the vehicle.

1.Load your vehicle the way it is driven most often, like whatever tools and cargo you normally carry with you.

2.Fill your tires to their max psi.

3.Drive to a gravel road or lot where you wont have to worry about traffic.

4.Get on your hands and knees at each tire and let the air out a little at a time until the shoulder of the tread is firmly planted on the ground. While you are letting the air out, everyonce in a while shove or bounce on the bumper of the truck to settle the tread because it will be changing shape as you deflate it. The golden spot is when the tread is planted the firmest and the sidewall is bulging the least.

5.Record the psi at each tire. Now after running low psi offroad or hi psi hauling a load you will always have the perfect psi handy when the truck is going back to normal duty.

This is the way to get the longest wear and the greatest amount of on-road traction out of your tires. NOT necessarily the best fuel economy... but you probably shouldnt be too worried about that running big tires anyhow...

31x10.50 15s on my lifted geo tracker I ran 18psi in front and 16psi in rears <--these were M/T radials
33x12 15 on my jeep I run 22psi in front and 18psi in rears <--these are bias belted M/T tires



YMMV

getting close to 3/4 mark, and ive gon about 205miles, cant fill her up until tuesday, getting painted.

[nofear4189]

i get about 15 MPG in my 92' EFI with 31's. Hey, im getting mine painted right now too. MAACO all the way. (the one here in York does good work unlike popular belief about MAACO)

im goin w/ earl sheib im getting there 800 dollar job and body work for 525$ so im stoked. royal blue metalic, what color are you getting yours?

[mooseketer]

Check the timing and try some injector cleaner. Techron is best, get the concentrated.

[sonofmayhem]

well i am just a jack ass and cant add. i got 220 miles, with 12.50~ gallons.about 17-18. thanks for all of the ideas, i am still going to check the timing, and egr. i used seafoam in throttle body, gas tank, oil. so that coulda helped.

thanks

[Geius Maniacal]

i get 17-18 mpg on my 90' 22re with 31's
ur tire pressure should help a lot. especially with a weaker engine

[sonofmayhem]

yeah i also noticed an increase in acceleration afterwards. in the winter with snow on the ground, would it be better to drive in 4wheel, with the tires air down, gotta drive to school

[karazy]

I was going to mention that you should wash the truck. You'll lose 100 lbs and get the aerodynamics back.

[sonofmayhem]

haha true, my truck has so much grease, and dirt build up on the bottom, but i think all of that grease helped.
