well, i have a pretty heavy wooden double full length drawer system in the back, the hefty fabworks aluminum front bumper with 10k winch, roof rack, plus recovery gear, sliders. seemed like standard stuff everyone is doing, is everyone else with simliar set up getting 12 mpg?
gas milage seems really bad at 12 mpg anyone else?

hmmmm, very interesting point.
i am going to go on a quick rant here. 2 weeks ago rented a dodge durango and drove the fam from oakland to seattle, hitting national parks. that durange is amazing, 24 mpg, a 9 speed tranny, tons of room.
WHY OH WHY after all these years, can't toyota put a good transmission in the 4runner and put a turbo on it as well. it's a no brainer in my opinion.
i love this 4runner but you know the old saying, it will pass anything but a gas station?
well toyota managed to make something that won't pass anything including a gas station. mine is fairly gutless, in my opinion.
i know this is a 4runner forum but has anyone researched other good simliar 4x4's that might get better milage with similiar setup, like 33's, roof rack, some xtra bumper weight and gearweight?

do you think you could feel a stuck caliper? like when you coast to a stop?
OMG!! i will go crazy driving long distance if I go under 70 mph!

Welcome to the 12 mpg club
i hope i get kicked out of the club!
Where did you get the blower done??

Check out my sig for my rig details. I've got about a 3" lift. I'm sitting right around 15 avg. More city driving = < 15 and more highway = > 15. That being said I usually don't go over 70 mph on the highway and I try to not have a lead foot.

I found that the computer calculation is not very accurate. It shows that I get about 17 mpg but if I do a manual calculation I get 18.5. The way I do it is like this. First, set your Trip-A meter to zero the next time you fill your tank. The next time you fill your tank, check the trip meter and write the mileage down. After you fill your tank, divide the number of miles on your trip meter by the number of gallons you just put in your tank. Your answer will give you you average mpg.
Here are some other things that can affect your mileage. Most have already been mentioned.
Oil - If you are running oil heavier than 0-20W this will reduce your gas mileage.
Oil Additives - like Lucas oil may help improve your mpg. Make sure you use the synthetic for “LIGHT WEIGHT OIL”. if you use the other synthetic or normal one you are essentially thickening your oil which will reduce your mileage. Lucas works wonders on engine that use a heavier weight. I’ve only had my 4Runner for 6 months and I’m still waiting to see if I’m getting better results. So far it looks promising.
Dirty Fuel Injector - If you have a older engine you most likely have a little carbon gunk build up inside. If you have enough build up on your fuel injector it could reduce burn efficiency a little which will reduce mileage. So try and runs some fuel injector cleaner through it. And since the fuel injectors on the 4Runner spray on the valves you’ll have the added benefit of getting those cleaned as well.
Dirty Engine - Same story as above but in the engine it turns into sludge. Just before a oil change run a engine flush for 5 min then change the oil. This will help remove sludge. I also, know some people who used Marvel Mystery Oil in their engine with good results but I have not tried this personally.
Gears - If you have a older car, check the fluids on your transmission, differentials and transfer case. Old oil can reduce efficiency. Just like the engine, these have scheduled oil changes too. Also if you have done heavy mountain climbing this can break down the oil quicker since you are running at higher rpms and if you were doing it in hot weather this will break it down even faster.
Breaks - Check and make sure your break pads aren’t riding on your rotors.
Skid Plates - I heard someone say that when he added skid plate that he ended up getting better mileage. His theory was that it smoothed the airflow underneath the truck. If anyone here already has some on their vehicle and noticed a change good or bad, please chime in.
Tires - Plenty of good info already given here. Just check your tire pressure.

Mine currently says 14.6 but I have not reset it since before the lift and tires and it has continued to drop. I am trying to stay oblivious to what it actually is but I know its dropped a lot. My driving style doesn't help.
The door sticker is only valid for OEM equivalent tires, if you are running E range tires 30psi is way underinflated and contributing significantly to your poor mpg
Lookup a load-inflation chart for your tires, you should probably he over 40psi

From the roof and up and over the rack to protect stuff (stuff, RTT, skis) as well. Water jet cut aluminum, bedliner, hardware is black now. Huge difference in wind noise as well. Modified hardware from Rhino racks fairing (theirs was terrible)

You need to reset the mpg computer and drive your normal routes for a week and then look at your mileage. Don't use "long term" mpg calculations over 28,000 miles. I would guess you will end up seeing around 14 or 15 mpg at best unless you change the rake (if that turns out to be reverse rake) and possibly take off that sail of a box you have up top. Even if it's "low profile", its catching wind.
Your on road tire pressure should definitely be above 30psi.... prob more like 38-42psi in my opinion. E rated tires can be heavy as f*ck compared to stock so that drops your mpg significantly, but your cooper 3's may be C rated. I definitely think you have quite a bit of weight added, but you should be seeing above 12 with just a few changes.
I am sure you've idled somewhere or been stuck in traffic a few times in the last 28,000 miles to be at 12.9mpg.
Maybe you hit up the Sonic drive through and keep the 4runner idling... you been through a drive-in movie lately? (They still exist) :snacker: Just some crazy ideas, but definitely happen!

Usually some noise but to be honest the parking brake barely registers against the torque.

Same here. I start nicely around 70-75, but within 15 minutes of watching the same cars trying to pass each other with a 1mph differential, it drives me nuts and then I find myself going at least 85.
that's a nice job!

So you’ve never reset your MPG counter?
Do you keep a notebook for hand calculating MPG for each fillup?

THIS
and these!
I have clocked my mileage every tank with the CarXpenses app since I bought the truck six years ago.
I have a 2.5/2.0 (leveled), extra weight (AL armor, battery, air, winch, fridge, rec-gear, passanger + dogs
), and had BFG KO's C-rated 265/70r17's for years until I wore them out. I'v averaged 15.6 mpg. Highway only trips I get 17-19. City I get 11-16. Offroad+highway same as City.I just "upgraded" to D rated Goodyear MT/R's 285/70r17 I have put in four tanks so far:
14.08 - city
12.59 - city + offroad + return highway
15.27 - city + highway
10.98 - offroad + return highway
So time will tell. I picked MT/R's specifically because they are D-Rated and NOT E-rated tires. C's I think are okay but this platform feels like it needs just a little more when you build it, even mildly, and E's are just overkill for general offroad and regular usage.
I too do think that going nose up really borks your mileage the most, second racks and crap on them. We are driving bricks, not as boxed as and FJ or even a Jeep K-series (which incidently get worse mileage than us) but bricks none-the-less
What do you expect if you want to go where you want and look cool doing it
