I spent a few months solely using my 2000 for commuting approx. 1 hour trip consisting of 99.9% highway miles. I live about a mile from the on-ramp and had training 2 blocks from the off-ramp. I have a lift and 265/75s. Even using cruise control the entire trip at 65mph, I averaged 19-20.5 mpg over 3 months.

This is on a highway running N/S so wind factor wasn't as much of an issue. I not commute mostly highway (60mph) on a E/W state route and avg about 17/18.

Probably negligible but depending on wind conditions can surely impact your actual mpg from one region to the next.

My 2 cents.

I have a 2000 limited with 220000. Just put ome 880/906 lift on and installed Hankook atm 265 70 17 a year ago. I drive from Asheville to Charleston every week for work and I get 20-21 every trip. I run 5 over the entire way, so usually between 70-75 the entire trip.

That pretty much aligns with my numbers. For me, 60 mph seems to be the magic number to cover ground and maximizing fuel economy. Above 65 mph, the economy starts dropping very rapidly.

Another thing to help in city driving fuel economy is to lighten up on the right foot. I'm talking about accelerating less, and when you see that you will be stopping ahead, let off the gas early, and coast. It is a rather foolish habit to race to a stop light.

Also, do the math: 5 mph more on a 15 minute trip really doesn't gain you anything noticeable (unless you happen to be late )

That's pretty good. I'm lucky to see 20 mpg if I'm going any faster than 65 mph. 70-75 mph gets me about 19 mpg or less.

Well, I forgot to put this here, but here's a way to get you 1-2 more MPG, see the post here for a few guys keeping tracking of the mpg gains!

And I have this system on sale as we speak. Forgot to even mention it in here. The old muffler is the size of a coffin, HUGE, vs the new one is like 30 lbs lighter and gets 2.5" tubing.

I ran the tank down to the wire once on a long distance trip.....the most I ever hit was 22.7 MPG - calculated from actual pumps fills and ODO reading.

My fuel economy has been off lately, I've done a lot of maintenance since I last measured it....not really changed but then the Runner only does short trips lately so eeking out 16MPG around town.

I got an AFR sensor and Fuel Filter waiting to go on though.

Mine was parked with damage for 2+ years. Prior to the damage, I never recorded better than about 18MPG. I just replaced the front brakes and the front bearings 2 weeks ago along with several other smaller repairs that were needed. I have, since, gone on long trips two different times. Each time I filled the tank before I left and then again when I returned. The first time I went 88.8 miles and it took 3.8 gallons totaling 23.36MPG. The second time I went 117 miles and it took 4.9 gallons totaling 23.87MPG. These were straight HWY trips with little idling and little stopping but I have been astonished to measure right around 24MPG which was unheard of in the past...

The mechanic that completed the bearing/brake replacement said that the bearings were f**ked. He said they were basically welded together and it was near impossible to press them out. He also said that he thinks they may have been compromised for a long time and I was lucky one/both of the wheels didn't fly off at speed. I wonder if that is why my MPG has increased. Having a compromised bearing is like driving through deep sand all the time. It must negatively effect MPG.

It's clear to me at this point that strictly HWY at 60MPH I am getting better than 20MPG which is crazy to me.
