    Re: ZF6 oil change

    Keeping the fluids clean and fresh...diffs, transfer case and transmission has been a key to success for me - almost at 190K and no whine or wear out on any of those components. I want to see 200K by the end of this year with no blown components. I have done diffs at 30K, transmission and tranny case at 75K. Now to be fair...both tranny and transmission have been very clean even at 75K so you could stretch it 100k, but since I'm towing quite often, I think it's cheap insurance to do the PM.

    Now...if I can only find a good pancake house tomorrow morning...and some Vermont Maple Syrup with a twig of Madagascar Vanilla bean...all will be good!

    Have fun with the project!

    Re: ZF6 oil change

    Just be aware that LR specify changing the oil at 10years/150,000miles (240,000km) if the vehicle is used normally. Must be changed earlier if used in arduous conditions such as offroad, towing or commuting. The reason for the high distance is to meet EU pollution requirements and waste oil comes under that so the longer the change interval the less waste oil.

    However ZF the makers of the gearbox and the standard fluid say the oil should be changed at 50,000miles - as well as the filter. Big difference between the two - I would lean towards the ZF interval. Replacing the plastic sump with the metal sump makes changing the filter easier.

    Reading many different forums I have yet to come across of an outright catastrophic failure of the gearbox - all failures have been caused by oil degradation causing wear and torque converter failure well before the LR service interval. There are exceptions though.

    My own box is about to get a metal sump and oil change (top up and drain then top up method) at 60,000miles though I only have the little 2.7 diesel not your high powered V8 petrol engines so my gearbox will not have as much wear and tear as most of the north american vehicles.

    I am also changing to a local oil that is 1/3 the price of the Lifeguard 6 but with the new sump I will change the gearbox oil every time the engine oil is changed.

    Isn't that somewhat contradictory? Your vehicle produces less wear and tear on the transmission and while you do a fair amount of arduous activity and offroading, you're going to change it every time you change the engine oil? That does seem overly excessive...what's the point of that?

    Because I would rather spend $70 on gearbox oil and about 30 mins of my time every 12,000km and once a year rather than $8000 on a new transmission. Noting it is not a full oil change just the basic drain and fill so only about 1/3 of the oil is changed each time - and the oil is not Lifeguard 6.

    That's funny math - so you'll change the oil 10 times at 1/3 the price per change, when you could go 75000 miles and change it once with the proper oil. The transmission is not going to implode...but Ok...seems like changing underwear 3 times a day.

    Just go without underwear and it's no longer an issue.

    Love Google...I own some shares.

    That's the 'non-normal' driving interval.

    An individual choice - if you don't like it don't do it. Simple as.
