    Question Isuzu MU-X 4x4 questions

    Hi all,

    Really like the look of the MU-X and went to test drive one two weeks ago.

    How limited is it off-road without the rear locker? Can the M-Locker be fitted after factory or must it be factory-fitted on new car? Are there alternatives to the M-Locker?

    What are the options for adding extended fuel tank?

    Regards
    Chris

    You can retro-fit a locker, not sure about brands available.

    My MUX spends its days (especially during the week) in deepish & loose sand, and when the rainy season rolls around - like now - in mud.

    Never been stuck, the traction control system does a fine job. For sure, it is not as sofisticated as more modern systems, but it keeps you going.

    I can imagine that axle-twisters / rockcrawling type offroading will see the MUX benefit form a diff-lock. However, personally I do not feel the lack of a diff-lock. And the same applied to the Trailblazer that I had before the MUX.

    In short - it has everything you will need and then some - for normal 4x4 requirements (and great articulation as well). It also helps that it is a tough as nails vehicle.

    As for extra fueltank, do not know. But consumption on the MUX will see you easily exceed 600 km's per tank - even in fairly tough going conditions. It rarely drops below 9.5 [email protected]

    I have not purchased one yet - considering it though. Just not sure whether an extended fuel tank can be fitted (I plan to do a Botswana trip next year) and if the lack of difflock will be problematic.

    Unless you plan on doing grade 4 or 5 obstacles, I would leave the MUX as it is - it is very capable off-road as standard.

    Wrt fuel consumption, if you plan on overlanding, rather carry a jerry can or two than incur the cost of an aux tank.

    What would the fuel consumption impact be of all the accessories fitted to this model here:

    If you're nearby or have a friend that's nearby take it for a test drive and check on the onboard computer it will give you an average fuel consumption.

    At almost 140 000 km's I can tell you consumption on the MUX is an issue extremely sensitive to the right foot. Much more than my Trailblazer before (I think because the TB had so much more toque).

    A test drive will not really reveal too much (sorry, Alex��), the only real measure is over time & distance. My best guesstimate would be less than 1 l @ 100 km. Drinking habits on the MUX is well behaved up to 130 [email protected] - after that it starts going seriously south - if my friend is to be believed. On my last tank I did 806 kms, by sticking to applicable speed limits and the OBC indicated 125 kms range left. This is on a 65 liter tank. However, I was in a hurry yesterday to get home in time for quali's so I just splashed & dashed, so I cannot calc the consumption.

    The diff lock is not that limiting. I am a complete noob and managed without it. It would obviously help but not worth it for me at this stage.

    i made it up here that day. This was my very first time doing any off-roading. So i think if you plan your approach correctly you should be able manage. But i am a noob....

    So how well does the traction control work in 4L? My frame of reference is the A-Trac (active traction control) on the FJ Cruiser. Allows relatively little wheel spin before it engages. Have not had to use the diff lock thus far.

    Really have no idea how to compare to the FJ. But I have zero doubt that the FJ will ultimately go places where the MUX will not go. For many obvious reasons, but mostly compact size of FJ and extremely short overhangs.

    The MUX will allow a bit of slip as well before traction control kicks in, but then, it needs that in order for the ECU to calc relative wheel speeds. It happens quite seamlessly.

    Personally I would suggest fitting A/T tires if shod with H/T tires currently. Now that makes a difference.

    Seams like a Harrop E-Locker can be fitted. Looking at about R35k including labour.

    Good evening. Anyone who has towed a 750 kg GVM trailer? What is the fuel consumption then like? And in thick sand? Can get a nice used model now but have a Botswana trip lined up for next year. Will need to travel towing a trailer for 500 km without fuel available - can work on 1000 km including game drive. This will be from Maun, to Moremi and Khwai and then onto Savuti and back to Maun. Will like to get an idea about how much extra fuel one would need to take. Can fit an ARB replacement tank that takes 112 l.
