my quest for 20 mpg while towing 1k
#21
The blaster is a 94 all stock and very clean other than then faded gel coat. I picked it up cheap for my wife to ride. The SJ is my real baby.
The SJ is mostly stock but I have added some REV foot holds and it has a b-pipe and stainless prop and a riva intake grate and ride plate. It is a blast thats for sure. Do you have one?

Well you can always punch your cats and throw some of the BG oil additive in there when you change the oil. Everyone who I've ever talked to about BG stuff says it works great and punching your cats will always get you a MPG or two... As long as you don't mind having your rig smell like a motocross bike. Make sure it's not illeagal in your nick of the woods too.

Ummm 20MPG.. no way.. especially towing. Those who think they're getting over 20MPG in a 4Runner most likely aren't calculating correctly or misinterpreting a one off. Either, way I doubt there are many pulling off over 20MPGs, and especially not pulling something. See the thread below for more economy discussions:

Plenty of people have gotten over 20MPG. Don't know why you're so skeptic?

Here is a part of a spreadsheet I keep of my 01 Taco:
Date-----Miles----Gallons---MPG----PPG-----Highway / City (percentage) Avg. highway MPH
4/9/08---196.9----9.424----20.89---$3.079---80/20----74
4/11/08--252.5----12.339---20.46---$3.079---70/30----72
4/14/08--236.6----11.996---19.72---$3.079---60/40----75
4/18/08--290.4----13.961---20.80---$3.249---70/30----73

4/25/08--189.6----9.074---20.89----$3.199---80/20----74
And from my 02 4Runner:
5/10/07--184.6----8.168---22.60----$3.019---90/10
5/14/07--201-----10.636---18.90----$3.069---20/75
5/16/07--224-----10.432---21.47----$3.059---70/30
5/21/07--193-----9.866----19.56----$3.059---80/20
5/23/07--180.8---8.512----21.24----$3.079---90/10
5/29/07--151.4---8.057----18.79----$3.119---40/60
6/1/07---294.5---12.837---22.94----$3.199---80/20
6/5/07---292-----14.076---20.74----$3.199---75/25
6/7/07---217.5---10.461---20.79----$3.109---60/40
6/9/07---231.2----10.58---21.85----$3.129---80/20

6/14/07--266.1---12.424---21.42---$3.089---80/20
6/16/07--219.9---10.282---21.39----$3.099---75/25
6/19/07--252.2---11.685---21.58----$3.149---70/30
EDIT: I will add that increasing the tire size to just +1 (265/75/16) dropped my MPG's from 21MPG to 18MPG on the highway. Very significant drop. I also compensated for the larger tire size in Excel. All of the above figures are from a 100% stock vehicle (265/70/16).

This is a pretty cool website. Most of this is stuff I have been doing in the honda for years but its cool to see it all in writing. I never go as far as turning the car off (unless I am going to be going down a huge will and clutch start it with out the use of a starter, obviously not an option in an auto 4runner though) Does any one have any idea how long it takes the efi to get back into a groove after you pull the fuse? We are about to pull the skis on a 4 hour road trip. I have used up about a quarter tank with out pulling so far.
Oh and for the guys asking I tow the skis with over drive on. They don't really weigh enough to need it off. hit it for some of the big hills but thats it.

As an experiment I drove 70-80mph for one trip and my mpg's dropped down to 15-16mpg's.
There are many things that influence mpg's when pulling a trailer such as aerodynamics of the trailer, outside environment (rain/wind/traffic flow), vehicle, driver (biggest one), and trailer miscellaneous (tire pressure and freshly packed bearings etc). So it is definitely possible to break 20mpgs consistently with the 3.4 pulling a trailer, barring unforseen circumstances like traffic flow and weather.
My 2 cents from experience.
Cheers

Yes way! I was getting 20+ mpg's pulling trailers on the highway with my 97 3.4 litre 5 spd 4runner stock. And no I am not calculating it incorrectly, nor am I misinterpreting anything. I consistently got 20-22 US mpg's pulling my apprx. 1200# tent trailer and loaded 4runner with family inside on several occassions. The key is to not be a lead foot; I drove between 55-60 miles per hour, and was easy on the braking and taking off. My best mpg was just a hair under 22.5 US mpg and my worst was 19.1 US mpg. All of this was done pulling the trailer through the Rocky Mountains, including 3 mountain passes.

thats what I like to hear. You are my inspiration. I will check my mileage on my trip this weekend and report back. I am not hoping for much since I just reset the EFI.

Hey ya'll,
I have a 99 4runner LTD 4wd, 3.4, locker, auto, roof rack and air deflector
for the sunroof and air deflector for the rear window.
Running boards removed. Michelin LTX MS 265/70/R16 at 37 psi all around.
and I use Scangauge II on my OBD II port. calibrated every time I fill up, which has been about 34 times now. It is dead accurate.
I am getting (absolutely, no question):
Highway
22.1-22.5 mpg when driving 150 miles with cruise control locked on 68 miles per hour
this drops to 18-19 when I have my large Saris ski box on the roof.
*drops down to 21 if I go uphill a lot, or through more than 3 tool booths.
20.5 mpg when going 72 miles per hour
18 mpg when driving the way I used to, fluttering between 75 and 79
17 mpg when driving like a dip
-----
City
18-19 when doing errands with occasional highway, and few stops
17.2 mpg when drivin, doing 4 and 8 mile errands, and avoiding the hills in my area
15-16.2 mpg when not avoiding some of the steep hills in my area
-----
these are the true facts for a cali-emissions dual-cat 1999 4runner with 150,000 miles, new plugs, spray-cleaned original MAF, new A/F sensor, new air filter, and it's third severe maintenance done (timing belt, all the belts, all the fluids, greased driveshaft) and pumping
'early spring new england formula' Exxon 87 octane.
no I have never used bg-44k or sealame I mean seafoam

PS: if towing a trailer, what counts is how the trailer is balanced, including it's wheels. Tire pressure,
and how you accelerate. you'd be surprised how low your initial takeoff mpg can drop when accelerating.
For instance. The throttle position sensor is at 20 most of the time on the highway getting 22 mpg.
But if you put it to 20 taking off, your mileage drops to 4mpg. or less. TPS at 13 is the best you can do, and then your mpg
is about 12-15 taking off, but you are going slow for a long time. there is a fine balance between getting
moving and wasting gas. Only a computer like scangauge can show you the sweet spots. sometimes
it is better to mash it and get up to speed then cruise. with a trailer, all bets are off. once up to speed you
should get at least 20mpg below 70mph with 1000 lbs and a top notch trailer.

Instead of calling BS, maybe you should try to put some thought into what you could be doing that's hurting your MPG's or potentially taking care of some maintenance items on your 4Runner.

It's not rocket science. Any idiot should be able to figure out the MPG. Fill up, drive, fill up again. Divide miles driven by how much you just put in = MPG. There will always be variables due to the inaccuracy of: your actual miles (odometer), gas pump auto-stop, climate, etc. That's why you need to do it multiple times. I commute 100 miles per day. Terrain and miles per hour all stay consistent. My 3 year average is over 20MPG.

Now I have a big, huge hard body travel trailer that's 4200-4300#'s loaded to the nuts with all our family's gear and my fuel mileage has dropped significantly (avg. 12.5-13 mpg at 60-65 miles per hour). I can still get 15-16mpg's on gentle rolling hills driving 40-55 miles per hour (where speed limit is posted at 50mph), otherwise the drag from my travel trailer causes my mpg drop to what I said above any time I drive faster than 55mph. It's amazing what pulling a big square box can do to your drag coefficient. LOL.
Good luck and definitely post your results. Hopefully they are close to or better than mine.
Cheers

Oh, and my 98 had 130k miles, my 02 had 90k miles and my current Tacoma has 106k miles.
Also, look at what kind of driving you do. Mine is 80-90% highway and I have my cruise set at anywhere between 70-80MPH. If you do lots of city driving or idling maybe that's where you're getting the lower MPG's.

I am also extremely skeptical that some people here can get 400 miles out of a tank of gas. I must have about 10 kilos buried in my truck somewhere because I'm not going to see 20+ unless I drive off a cliff.
