Rear diff oil

[anonymous-user]

Want to do a diff oil change - myself. Is it easy - i.e drive the car for a bit to warm the oil, drain via plug and refill?

What oil do I use? I used to use some special castrol lsd oil for my old Commodore GS/E.

Redline and friction modifier.

You could consider,

Castrol SAF-XA if you've been happy with their stuff before. Requires no additives or modifiers:-

Product Description
Castrol SAF-XA is full synthetic SAE 80w-140 GL5 limited slip differential oil. It has been reformulated to supersede the previous Castrol SAF-XA SAE 75w-140 formulation. It has improved oxidation stability and high temperature deposit control while retaining excellent wear protection performance. The formulation now incorporates the preferred limited slip additive, Sturaco 7098, for Ford and Holden limited slip differentials at the maximum recommended treat.


Product Application

Castrol SAF-XA is primarily intended for use in rear axles of Ford Falcon and Holden Commodore high performance models. It contains the preferred limited slip additive and at the maximum concentration recommended by additive supplier.

The upgraded Castrol SAF-XA has been successfully used in V8 Supercar axles in place of previous Castrol SAF-XA SAE 75w-140 formulation and provided at least equivalent wear performance.

1]Both limited slip and non-limited slip hypoid axles
2]For vehicles towing caravans or heavy trailers
3]Covers rear axle viscosity range from SAE 80w to SAE 140
