New numbers on 2002 by duke15

The mpg numbers on my 2002 had dropped by 2 mpg, and didn't get better after the 90K mile service, done at 88K miles. But it looks like I am back to the mpg I got when new once I hit 91K miles - I just got 24 mpg driving mostly highway, one day trip at 70 - 75 mph on I-95 south from Northern VA to South Carolina - with 20 minutes of heavy rain at 20 - 40 mph. The next tank with about 75% highway, 25% mixed, with much more idling with AC on, gave me 20mph. The next important issue with my 4Runner is... surfboard rack for the roof. God I love my 4Runner!

careful with the computer by nedzel

The gas mileage computer on my 2003 V8 4WD 4Runner is about 2 mpg optimistic. It shows about 19.5 mpg. The best way to accurately determine mileage is to fill the tank, reset the trip odometer, drive a few hundred miles, then refill the tank and divide miles driven by gallons used to refill the tank.
 
My most recent fillups have shown that I'm getting about 17.5 mpg in mixed city and highway driving, about 2 mpg less than the computer reading. I'm driving with a light foot, keeping highway speed about 60 mph, coasting to lights, turning off the engine while stopped at traffic lights, etc.

I have a 2WD V6 and just took a trip from Texas to California. I actually got 22.5 MPG REAL mileage (computer read 24.2) at one point. That's cruise control on about 75 MPH, good weather, no wind, no traffic (there seems less these days), and relatively flat traveling.
 
check out www.fueleconomy.gov
 
You can register and see what other owners are getting....we need some 4runner owners on there, because right now there are only 2 of us sharing info.

Hello. Just pick up a 2004 Limited with V8. Is premium fuel needed?

go with your owners manual recommendation - in my experience with Toyota vehicles you can't go wrong with that. no need for premium, they run great on regular.

trying to improve MPG by chilisquid

I have a 2004 4runner, V8, 4WD
 
I used to get 20 highway, 16 city. That was in the USA.
 
My vehicle is now in Thailand, I am working here. I do plenty of highway traveling (2 hour drives at 70+mph) It seems that my computer never reads more than 16.6mpg. what gives ? I have tires inflated to 35psi. I have always kept up with maintenance.
 
It seems that I first started noticing the lower MPG after I tried a couple tanks of the gasohol that they sell here. Could it be that the gasohol caused a problem ? I switched back to gasoline (95 octane) and I am still getting only 16.6. seems my computer is stuck on this number. most of my driving is highway.
 
any ideas what I can do to improve MPG ? I always used to get 20+ highway in the states. once I hit 24. Could it be that the gasohol caused problems with the computer ?
 
Gas here is 39 baht per liter. I have an 80 liter tank. 33.40 baht to the dollar. thats $100 a tank.

2008 4Runner V6 Limited 4WD by rasmaxwell

Based upon miles driven divided by gallons used over 7500 miles, I am getting a consistent 18-19 mpg in suburban driving and 21-22 mpg in highway driving on Ohio roads. I drive at 0 to +5 mph over interstate speeds. My driving is 90% in 2 wheel mode. If you run in 4 wheel mode on the highway, you will get about 1 mpg less. Best was 25 mpg on a 100 mile highway trip with a tail wind. The onboard trip computer is consistently 1.5-2.0 mpg optimistic, so do the math yourself. Runs very well on any major brand of regular gas.

Getting almost identical numbers as rasmaxwell including computer being about 2
mpg optimistic. I run regular 87 octane gas, but have experimented with 89 octane and seem to have gotten a mile or two better mileage although obviously not under controlled conditions. I think if I really tried and drove like a hyper miler never going over 50 mph etc I could get 23 or 24 real mpg.

turns out I needed to reset my computer. Once I did that, and kept it at 70mph or lower, my computer read 20-21 mpg on the highway.

Low Low MPG in my 2002 Toyota 4Runner by snobound7

Does anyone have any advice on what I can do for my poor 4Runner?
 
I just bought it used a two weeks ago and right from the start I noticed it using a lot of gas. I was encouraged to test it and told that they really do not do too badly so not to worry. Well after driving it for about 1,000 miles I have verified that it gets between 10.2 - 14.4 MPG and that is taking it easy, keeping it around 65 on the open road.
 
I have gone back to the Toyota dealer I bought it at and ask for some 'warrenty' work to be done to bring it up to better MPG. They told me that all checks fine on the computer - no error codes and I owe them for the bill. The 'warrenty' apparently only covers MAJOR items.
 
Also, does anyone have trouble with the 4-wheel drive not engaging at very cold temps such as I do here on the mountain (-15 degrees). It takes a full 2 to 5 minutes before it clunks into 4 wheel drive. I have tried driving slowly (15-20 MPH or stopping and shifting to Neutral then pausing and shifting to Drive or stopping and trying reverse, then neutral and drive. It just blinks and appears 'stuck' in limbo - not in or out of 4 wheel drive. Since the 4wheel drive worked when they looked at it; no repair work will be done.
 
When I talked to the dealer they told me that I should have bought a Lexus and that I have a 2nd rate vehicle - what did I expect for buying a 2nd rate car. (*!#!*&%)
 
The 4Runner has 120,000 miles on it and the dealer tells me now that it is worn out and I had better buy a new car at once. It looks just like new; I hate car sales BS especially when the dealer does not stand behind their sale 2 weeks later. (This is supposed to be a reputable dealer - lot of my family and friends have bought cars there with nothing but glowing reports...)
 
The 4Runner ran quiet at first, now it creaks and groans and sounds like it aged 10 years in a week. Still however it looks like showroom new. Is this just the nature of the beast; creaky, clunky, and all the rest? I hope not. They must have sprayed 10W40 in all the joints...
 
I have the V6 engine and it is a 2002 model. :
 
Thanks for your help.
