V8 range

Just looking to see what you guys are pulling in your v8'S. I got 275 miles on on about 18 gallons of gas. That was the first tank and it was from the dealer so it might be a little off

Also what do your trip computers read after fill up. I believe mine around 340. I have only put about 350 miles on it. I think the computer was reset when the dealer detailed it when the cleaned up the battery and engine. I have read that it takes time to fully adjust.

Not looking to start another mpg thread. I found similar info for the v6 but not as much on the v8.

I've got a V8, 2WD though, and I believe the tank (per the manual) is 23 gallons and I typically get 370 miles or so, when I fill up. I think it depends and I've read on other threads that the computer is actually (IIRC) about 10% off.....someone correct me if I'm wrong.

I get about 370 Miles, about 18MPG V8 LTD AWD
 
With my 05' Sport 4x4 V8, I can sqeak out 340 or so before I get worried about running dry. I normally have 1.5-2 galons left when I fill up, so 350 would be a safe bet for me. That's 90% highway and an occasional lead foot!
I'm sure slowing down to 70 would help but all in all I'm happy w/ the range to have the added power of the V8.
I catch myself calculating the range based on my appx mileage since the computer reads 1mpg high. Once that range meter hits "0" all bets are off, although I have a pretty good feel for going 45 miles past zero if I've been easy on the gas pedal!
 
I think one thing that affects our range is the gas formula(summer, winter plus more, more and more ethanol)

My highest range since owning it was yr 2008 up to summer of 2009. My range were from 355 to 368 and a one time 372. Year 2010/11 my range don't read past 350. My recent fill up was 344.

I have 2WD and stock size tires. The 4runner is my DD.
 
320-350 depending on driving. I do quite a bit of highway driving and usually get around 350 miles per tank. 320 miles per tank when mixed driving (highway/city). I have a 2005 V8 with stock tires. Looking for that to drop when I upgrade my tires next year.
 
Not to ruin results, but; even a few PSI difference in tires can result in 10% +/- fuel efficiency.

Also, the type of tire. Only if were all running the same, stock tires would this be of worth. Anyone else here every taken advanced statistical analysis? When I got my M.A. I had to take many classes on research methods... tons of math. Gross. But it taught me one think. You simply can't compare as easily as we think.

The hated "Spurious" data and unknown variable creep affects everything.
Meaning. How you drive. What you drive, where you drive, gas you use, tires you use. PSI in the tires. Load in back and front. Ambient Temperature. Air Filter and Oil quality.

The list, my friends, goes on.. and on.. and on.
 
Saying how far you go on a tank of gas is not Rocket Science. At around 310-325 I fill up and usually take about 18-20 gallons. Combined city/highway and actual mileage is around 17-18 mpg. Things change drastically when towing though.
 
No. But replication in another vehicle with another driver is what I was referring to.

Everyone can do simply math. Gallons used by miles driven. Got it! What I was talking about is the actual value these sort of comparisons play out. My car goes X, well mine goes Y... you can't accurately compare the 2 without eliminating some substantial variables.

It isn't rocket science.
 
Not disagreeing at all. I watch my gas mileage on all my cars very close. I do get 1-2 mpg difference winter vs summer. I keep my tires at about 35 psi which is quite a bit more than factory recommendation on any of my cars.

One thing I found very strange in my 93 Suburban years ago was that it got better gas mileage on lower octane gas. Everybody is always saying put higer octane in for better gas mileage, but I have never found that to be true on any of the Volvos I have driven or the Suburban. Have not tried that on the 4Runner or the BMW. I run 87 in the 4Runner and 91 in the BMW.

One time I did put better than 22 gallons in the 4Runner, but part of the tank was used for towing so miles was probably less than 300.
 
I get about 300 or so with BFG's and 85mph on the highway. I don't keep track. It depends on the weather and terrain. I use V-Power.
 
I have always averaged about 16.5 all around. I drive mostly suburban roads and when on the highway average about 20mpg.
 
Just got my V8 awd 4runner but it only gets roughly 270
miles of range when filled up. I'm curious because looks like people are getting way more than that going all the way up to 370. Currently has a catalytic converter check engine light but It passed smog a month ago so might just be the O2 sensors. Do you guys believe the range is this low because of the engines age ? It's got 220k miles. Or is there definitely something bad that's causing my range to be so low
 
Your range is constantly changing, depending on the terrain, driving habits, traffic etc. But it is over all of your driving since the last reset; city, highway, towing, everything. Reset mpg and range then drive the course you want to test and see what the range is then. The better the mpg the higher the range will be.

Go down a long hill and reset the range, mpg etc. and your mpg goes through the roof. If I pull my travel trailer the range stays fairly high unless I do a reset, then mpg goes down to 9, greatly impacting the range. I park the trailer, do a reset and drive the Interstate and my mpg goes to 18-19 mpg and the range is well over 300.
