Thread: Locking rear diff - which oil!

Buy the correct oil - the front diff oil can be sourced in auto shops, the correct transfer case oil is only available from dealers and is a bit expensive but you dont use much. Buy the e-diff oil from the dealer to ensure you get the right stuff.

Despite what Reback says the e diff oil is different to the standard diff oil.

The standard diff is 1.1l of Castrol SAF-XO - 75W/90
The E-Diff is 1.5l of Castrol SAF Carbon Mod Plus

Both your recommend diff oil's are not listed on castrol australia's website (I'm not saying its not available in Aus as I live in a regional area with only a real basic autoshop so I can only rely on what I can find online).
So if they are not available retail then you either buy an oil from the dealer or look for an oil that can cross reference with the spec you need. I've personally got no issues with using another lubrication product where it exists, and for me ording oil online is much easier when not dealing with dealers. Plus my disco isnt new anymore.\


Royal Purple recommend Max gear 75W-90 for both normal and e-diff

This oil has been superseded by Castrol Syntrans Longlife 75W90 which is available from any Castrol distributor or reseller.

No worries - as I said it is the owners choice - I would rather pay the dealer a little extra rather have to pay for a new component. There have been two alternatives listed for Lifeguard 6 that have subsequently had the alternative listing removed - same with some other oils.

Owners choice.

Topix still has the original oil listed - maybe superceded by Castrol but it would seem not by LR at this stage.
