how many miles does your 4 banger get on one full tank??

i'm going 420 miles and putting in 18 to 19 gals of gas. it really depends on my driving habits that week.

 

Ya. In my Suburban, I had a 42 gallon tank, but I'd gas up every 3 days because if I went 4, I'd have to swipe the card twice because it was over $100.

On the Taco, I gassed up every 4 days for the most part, but now that I'm comfortable rolling over halfway home from work with the light on, I'll go 5 days now.

Some weeks I won't get a light in 5 days, other days the light comes on just as I'm leaving work.

I've still never put more than 18.1 gallons in.

 

since i levelled my prerunner and went to 265/75-16's im pretty much 19.5 to 20.5.a mix of city mostly highway,back and forth to work.

 

The best mpg I got was 24 on winter gas and lowest I got was 20 . That's highway and town combined. Last tank I,went to about 316 then filled up but forgot to figure out my mpg once the summer blend comes back I bet I can,average 25 or better if I keep my foot out of it.

 

Looks like im getting street tires next i want hat milage!

 

Shit!!! I wanna get 18x12 wheels and some street tires...going HI style! I want em that wide cause it would suck to have a 8 ich wide wheel and not stick out enough for me

 

Yeah i understand that but chances are i may not like the wheel or it just may be rediculous on price, hard to find and what not..
I want a bigger size wheel if im gonna do this though look funny on a 15x8

 

Well i have another im gonna put em on tomorrow actually..255/70/16 michelin ms2 on 16x8s
Hmmmm probably $8500...with the extra set of wheels i have for them and the subs/amp, double din and stuff
Might seem a little over priced to some but it has 165k now

 

Keep in mind that a tire size change also changes the odometer reading.
If your truck came with 245/70-16 and you go up to a 285/75-16, then down to a 255/50-17 street tire, your calculated MPG and odometer readings will vary as follows over a theoretical 300 miles, with NO actual change in fuel used traveling from point-A to point-B:

245/70-16 - 18 MPG - 300 Miles
285/75-16 - 16 MPG - 270 Miles
255/50-17 - 20 MPG - 330 Miles

It might feel good to see a calculated 20mpg, but the fact remains that you still used 16.67 gallons on a road trip from St George to Salt Lake City.

Now, the smaller street tires are lighter, so there will be some fuel economy improvement from that. They also lower the effective gear ratio. Theoretically, your city MPG will improve, but there will be a loss on the highway.
Driving the 6spd manual with the 255's in 6th will have the engine spinning like the 285's in 5th.

But the only way to know where you are on MPG is to use a GPS when your tire size is changed.

 

Cause they keep their value so well !

 

Wow i would only dream to get that in mine!

 

And 400 miles is nothing on the 2.7 if you have a 5-lug...

Remember, 2nd Gen has a 21 gallon tank. With my best tank at 25.9 (ignoring the 26.7 aberration on a road trip) and my worst tank at 22.87 (ignoring the 22.1 aberration on the same road trip), I can guarantee at least 435 miles per tank, leaving 2 gallons in reserve.

On the 1/3/13 I added 5 gallons on 1/2 so this fillup was a total of miles and gallons for both stops, I didn't run it down completely empty.

 

I run two sets on my 3" lifted 2.7L 4x4 AC.
Street tires are 265/75/16 Dungflops (until they wear out then 265/75/16 Dynapros) and I get around 24 MPGs hwy on summer gas. City MPGs are around 20 MPGs.
Trail tires are 255/85/16 BFG KM2s and my MPGs vary from -2 (hilly) to +2 (flat) hwy. City MPGs suck!
Two sets make sense. Better MPGs for most miles & save the better traction tires (& more expensive tires) for off road.

 

But your numbers were artificially deflated by the larger tires.
You actually drove more miles than indicated.

Think of it as an extended warranty

 

You're probably pretty close to reality (if not comparable to other trucks).

Those tires are 7% over the stock 245's, but if the 4x4 is like my 5-lug, the speedo is off by around 3-5% anyways, which would mean that 265/70s would put it pretty close to accurate.

 

285/70/17. stop and go from cow town to cow town. 331 is my best tank with fuel light

 

I hoping to get at least 3mpg back from switching to the other wheels and tires ima start alternating them and run the smaller i the winter and bigger in the summer...probably gonna keep the snaller set on till the SPI meet in july

 

Speed is of with stock tires but odo is correct.
With 265/75/16s speedo is correct but odo reads less miles than traveled.
I use my GPS info to show correct speed & to figure MPGs.

 

Sounds right.

Same with my 5-lug and my motorcycle. The odo error is about half the speedo error.

But it's really not that much of a difference percentage wise. A 3% error is only 9 miles every 300.
18mpg becomes either 18.5 or 17.5 on a 3% error.
You're going to vary more than 3% from tank to tank.

 

175 on half a tank for me !!! With these small ass tires
