    I asked the same question of Alde UK and got told they use a Comma brand product in their service dept in the UK..

    It has to be a Glycol based product [some modern automotive ones are not] and many older cheaper antifreezes only have two year life corrosion inhibitor package. It must also be very specifically for aluminium engines, to have a suitable inhibitor package.

    One Comma one that I found has a five year inhibitor life however personally I am focusing for this summers change to using a new generation Land Rover product which is again a 5 year life. If its good enogh for their expensive aluminium engines it should be fine here?

    With these new generation but still Glycol based fluids, there is a strong makers recommendation to flush out all the earlier two year fluid as the two generation inhibitors are not completely compatible.
    So my intentions are to flush well by refilling twice with clean water and then refill with this Land Rover 5 year product. The two year change just comes round too frequently. Time will tell if its a good choice.
    A main dealer just stuck in anything to hand during a service; I went ballistic but they claimed I was the first to ever ask.

    I am not qualified to give you hard advice, the knowledge I have is based on guidance given to me;
    Based on that my personal concerns is that its not an Ethylene Glycol product but a low toxicity Propylene Glycol product, and I was advised against using "organic acid" types. The latter, OAT [organic acid technology] I was warned not to use.

    It does claim compatibility with all other coolants and that alone rings warning bells as being too good to be true based on what I have been told.

    Land Rover's "Extended Life Anti-Freeze Coolant" is specifically an Ethylene Glycol based product an so is in my book a "safe", if not the best product to use. It is very toxic, but thats not an issue that concerns me much.

    Just had this reply from Alde

    "Hi, Yes use motor vehicle engine antifreeze (ethl Glycol). The solution should be premixed 40% glycol 60% water before pouring into expansion tank."
