Toyota 4Runner

    Perhaps I can be the first one to post a giggle over this typo. I'll bet hotelseven means 13.5L/100km, unless his 4Runner is powered by 4 big turbofans and travels at 600 MPH.

    Galileo757, there are several posts in this thread that deal with the use of regular fuel, including one or two of mine. Briefly, it's ok to use lower octane grades, as the engine has a knock sensor and adapts. You won't get lower mileage, just lower peak horsepower. In fact, you should get slightly better mileage on lower octane fuel.

    "13.5 km/100L of fuel"

    You crazy canadians.......8^)

    I hate it when I get interrupted in the middle of a post and somebody beats me to it; I was figuring somewhere around 3 gallons to the mile. Sounds like M1A1 territory...

    I don't have any experience with superchargers but I do remember some talk about a "knock" problem with the TRD superchargers in the past. A third party company was offering a box that changed the spark timing to eliminate this problem.

    It is kind of odd that the TRD website doesn't have the 4.7L supercharger on it even though TRD makes it. I did see it on for $4,699.

    It looks like there's a different part number depending on WHICH specific 4.7L V8 vehicle you have (4Runner, Sequia or Tundra) and in some cases which year (Tundra).

    The site has a lower price for the Tundra supercharger.

    My friend is on the market for a new SUV and he is leaning toward 4Runner (other options are Pilot and Pathfinder). What he can't figure out is how 4wd system works on 4Runner. I though I would be able to figure it out myself as I know how it works on my Rodeo but it looks like I am clueless as well.
    What we were able to dig out from the specs is that V6 4Runners (that's what he is looking at) got "mufti-mode part and full-time 4WD). Also, it looks like that all 4Runners have "ABS & Driveline traction control" which I'm not sure have any connection to 4WD system.

    Judging from what Isuzu uses, I got an impression that part and full-time 4WD is analogical to Isuzu's "Torque on Demand" where you have an option of using 2WD, All-time 4WD and part time 4WD. The difference in Isuzus was that when using "all-time 4WD" you were not required to be on wet/slippery road. When you manually engaged 4WD (on Isuzus) you had to be on wet/slippery road. Is it the case with 4Runners as well or Toyota meant something else? Also, do 4Runners also offer 4WD-Low? Is it used only with manually engaged 4WD? Any additional comments/suggestions/"for dummies explanations" will be appreciated. :-)

    Hey Guys,

    Thanks for the speedy replies, I did not mean to start another same topic msg thread that has already been hashed out. Premium unleaded gasoline here where I live is .20 US cents more then regular, maybe a compromise with mid-grade 89 octane. Good to know the V6 can use low end octane gas and higher than 91 octane racing or Computer and knock sensor for timing adjustment, wow technology is wonderful.

    Just got a new 4 Runner Limited three weeks ago.

    I had posted earlier.

    Ran it on a quick trip from Santa Fe to Las Vegas, NV, could not have had a better experience with a vehicle. V8 decent mileage of 21-22 MPG, using midrange gas. Owner's Manual calls for at least 87 Octane, but suggest 91+ for better performance.

    I have no squeaks, rattles, thumps, or rotten egg smell.

    I have a first class truck, which is what I wanted.

    Can anyone comment on the stiffness of the 4Runner suspension as compared to other similar SUVs? I mean the standard suspension, and just the general bumpiness on straight roads. I drove a Honda Accord before my 4Runner, and sometimes I feel like I'm tossing a salad in my new truck. Only if there are bumps in the road, of course. Its not too bad though-I'm just curious, compared to the likes of a Montero, Trailblazer, Explorer, etc, if anyone has ridden in those + a 4Runner.

  • hotelsevenhotelseven Posts: 33
    Can anyone suggest an after-market GPS system that could be attached to the 4 Runner? I'm not looking to spend huge dollars but I would like a colour screen, and perhaps something that is portable....Any suggestions?

    I have the V8 03 Sport and discovered something this past week. When driving 45-70 and put the petal down with either of the following, window down, moon-roof open or back window cracked I get the exhaust egg smell in side the truck. Called Toyota and thier are cases that have been documented and many complaints.
    At the present time Toyota does not have a fix for this. If you see where the exhaust ends right under the bumper it makes sense. Poor design. Some suggestions were given to me were get an extention that points down or have a muffler shop bring it out the side. I think and hope Toyota will correct this soon. What is the sense having windows if you can't use them. Anyone having this problem. I have 5,000 miles on the vehicle.

    Go to the main SUV conference page and look up the topic, "Toyota 4WD Systems Explained". Go to the first four posts. Most of your questions will be answered there. I wrote that explanation before the new Runners came out and there is only one difference with them. They now have a Torsen center differential which never allows all the power to go front or rear. You always have some power at both ends.
  • bcmalibu99lsbcmalibu99ls Posts: 625
    Cliffy1 said it doesn't allow all the power to go to front or rear, but it seems to be inconvenient. What if your front wheels get stuck? It means this diff won't allow 100% of power to go to the rear wheels. Kind of strange, no?

    Check out this extensive thread by me:

    It will answer most of your question about Torsen Center diff...just scroll down.
  • sovangsovang Posts: 56
    I read the tundra FAQ and it says that the "clunking problem" only occurs on some Tundras. My question is; can this problem be fixed for good or do I continue to grease the hell out of the yoke for the next 5 years? Also, why does it only occur on some runners and not all?

  • coranchercorancher Posts: 232
    I am probably making this harder than it needs to be, but I got tired of reinventing the wheel each time I wanted to convert from the L/100km convention of our esteemed Canadian neighbors to our MPG ratings. It is a bit of an odd thing to do, though, as their base unit is distance and they quote a volume, while our base unit volume and we quote a distance.

    Anyway, this seems to work: If you're given a rating in L/100km, just take the number 282.5 and divide it by the L number. This will yield MPG. Thus Galileo757's 13.5L/100km is 20.93MPG.

    Which is not too bad for a vehicle of this mass and horsepower, by the way.
  • sovangsovang Posts: 56
    I know very little about cars/trucks, but would like to try and grease the slip yoke on my 03 4runner. Could someone provide some tips or point me to a website where I can find some help.


  • jaredmsdjaredmsd Posts: 127
    Oh man oh man, you have stumbled upon the mother load. This topic has been discussed, rediscussed, flamed, everything. Try searching for 'egg', 'sulfur' and even spelled wrong 'sulfer'. You will have a ball. BTW, sorry that your are one of the unfortunate ones.

  • steverstever Posts: 52,572
    I was looking around some "octane" sites yesterday and one place mentioned in passing that if you burn premium, you may notice the sulfur smell more than if you run on regular.

    Perhaps it's time for someone with the smell problem to test drive a few tanks of the lowest-octane stuff from the scuzziest off-brand station in their neighborhood and see if that helps?

    I only use regular gas in my SR5 V8 and have NEVER suffered from the smell. I'm not sure if that's luck, or a scientific correlation.

    After 2,000 miles my gas consumption is averaging out at 19.6 MPG, in mixed driving.

    Ah yes, but is this Miles per US gallon or Canadian gallon?
  • Boris2Boris2 Posts: 177
    I'll look there... I'll let you know if I have more questions...
  • coranchercorancher Posts: 232
    Very funny, billf6531, let's just hope nobody takes you seriously. This conversion stuff is strange enough already. Fiddling with Canadian gallons would just make it worse.

    Next thing you know, you guys will be asking for something like drams/furlong!
  • tidestertidester Posts: 10,059
    I agree! That's taking things a bit far because a dram is a measure of weight so your conversion will depend on the brand and type of gasoline (they all have different specific gravity).

    Still thinking about buying a 4Runner and have been checking this site regularly to see if Toyota comes up with a fix of the smell issue. Love everything about the vehicle but my wife just won't let me buy because of the smell issue...
  • stephend2stephend2 Posts: 21
    Actually there's a 20% difference between the imperial gallon and the U.S gallon. So If you could be out by a bit on your conversion. However we all find this a pain in the but so lots of use the conversion chart made for us on Freds TDI page ( for Vw TDI people)
    Pls go to and use the link on the lower left side of the main page. Now all problems should be easy.

    Steve d. 2003 runner sport. (no smell)
    Awesome truck bur need some bush bars for the side so my kids can climb in easier. Any one have recommendations?
    Also the fog lights don't through as much light to the side as my previous Sequoia did. I really miss this on country roads as we have a lot of deer here. Any one have ideas on that?

    Actually I wasn't trying to be funny. I think your calculation, resulting in 20.93 MPG, was per gallon of Canadian gas. A US gallon is only .835 of a Canadian gallon. Therefore your mileage would be 17.48 miles per gallon of US gas.

    Anyone want to re-do the calculation from scratch and verify this? BTW, I used 3.8 litres per US gallon, and 4.55 litres per Canadian gallon in my conversions.

    EDIT: I saw Stephend2's posting referencing after I posted this note, and plugging the 13.5 litre value in gives the correct MPG in both Canadian and US gallons. Neat stuff!

    I just wanted to add one little comment regarding the smell from the exhaust. I have a yellow lab who LOVES hanging her head out the window. One of the reasons I like the Runner is because of the rear sliding window. Now my poor pup has to stick her head right into that egg / ammonia smell from the exhaust. Hope it wont hurt her....
  • coranchercorancher Posts: 232
    Billf6531 you are absolutely right about the Canadian/Imperial gallons. I grabbed the liters/gallon conversion from a US website and just assumed that it was US gallons. I feel especially silly because, while I didn't know the exact figure, I sure as heck knew that there were less than 4 liters/US gallon. Why the 4.546 liters/gallon figure didn't raise alarm bells when I saw it is a source of mystery and chagrin.

    Anyway, if you find yourself wanting to do the conversion and don't have a web browser handy, (that site IS nifty) the real figure to divide by your L/100km figure is 235. And the result (in US MPG) of 17.5 is more realistic for a V8 in mixed driving. Thanks for setting me straight.

    I have found this site to be extremely useful. It can convert just about everything.

    Hi everyone, I'm new to the 4Runner forum, having been a former GMC Envoy owner. I just traded off my 2002 Envoy SLE for a Black 2003 4Runner SR5. Dealer had equipped it quite nicely w/ 17" wheels, moonroof, side curtain airbags, dual cargo, 10 speaker JBL, painted stripes and a clearbra.

    For anyone interested, I have posted a bunch of Toyota and aftermarket accessory part numbers for the 2003 4Runner in the "Accessories and/or owner's club?" discussion...

    Has anyone found a good price on aftermarket auto-dimming electrochromatic mirrors? The best dealer price I found was $157 for one w/ compass. (listed above) The Gentex and Donnelly sites show pricing much steeper at closer to $200.
