    Here is some updated information, and as a reminder there is a difference between Initial oil fill, and an oil change. I use Royal Purple, I have pasted in the Oil I use at the end of this. This oil is available from Pep Boys, however, the last check they did not have the V8 Engine Oil filter so I have been ordering that online.

    I can provide you a contact at Royal Purple if you want to try to formalize something. This stuff is not cheap. I have no agreement with them, I just promote the product on LR because I like it.

    The transfer case should be done every 40-60k miles (at your discretion, and based on how hard you are using it) The Differentials fluids-- I normally tell people once every 30k miles or so.

    The transmission, this is a big one, and everyone misses is, LR recommends service at 150k, that is twice the service life of the fluid. The Lifeguard 6 is rated for 75k, so change it (pan/filter) every 75k).. Transmissions & transfer are expensive, especially from the dealer, the good news is I have both.

    Open Unit:
    Castrol SAF–XO
    Initial fill:
    1.23 liters / 2.59 US pints
    Service fill:
    1.18 liters / 2.49 US pints


    Electronic Unit:
    Castrol BOT 720
    Initial fill:
    1.77 liters / 3.74 US pints
    Service fill:

    1.72 liters / 3.63 US pints

    Front Differential:

    Castrol SAF–XO
    Initial fill:
    0.68 liters
    1.44 US pints
    Service fill:
    0.61 liters
    1.29 US pints

    Transfer Box:

    Shell TF0753
    Initial fill:
    1.50 liters
    3.17 US pints
    Service fill:
    Fill to level plug

    Transfer Case: Royal Purple Synchromax (part #01512, quart bottle)
    Differentials: Royal Purple Max Gear 75W-90 (part #01300, quart bottle); 0.65 quart for the front and 1.6 quarts for the rear

    Motor Oil, Royal Purple 5x30 or Royal Purple 10x30. Royal Purple Filter;
    V6 4.0L FI
    Filter # 20-820
    4.4L V-8
    Filter # 20-2009.

    Kindest Regards

    Sorry to revive an older thread, but the front diff level instructions have got me scratching my head:

    5. Fill with 0.61 litres (1.07 pints) (0.64 US quarts) Castrol SAF-XO - 75W/90 (LRN 7591)
    CAUTION: Do not use the fill plug as a level, fill with the correct quantity

    How have people been measuring out 0.61 liters or 1.07 pints? By eye?

    Hi All,

    Great thread! New here and looking to change 2011 LR4 HSE drive fluids (75k service) on my girlfriend's LR4. Went to Newport Beach dealer today to get the fluids. They told me to "fill until spill" on the differentials. This is how I've always done it on other cars, but after reading this thread I'm a bit confused. I had them call back and verify with the tech on hand. I mentioned reading online the capacities are much lower- Of course they blew it off as people not knowing what they're talking about... Anyone have the actual shop manual and could send me a snap shot of the instructions?? They wouldn't show that to me...

    Thank you in advance!
    Ryan
