As the BOA 90LS rear diff oil isn’t available from the local Silkolene branch office here in Greece, I try to find suitable diff oil for my car (MY2000 Euro spec).
Is the Castrol SAF-XJ 75W-140 right for the rear differential?
“Fully synthetic SAE 75W-140 hypoid gear oil formulated for use in both conventional and limited slip differentials. Whilst being suitable for all applications where a lubricant of this quality is specified it is specially formulated for use in limited slip differentials fitted to Japanese vehicles requiring an SAE 75W-140 Extreme Pressure Gear Oil. Castrol SAF-XJ is also specifically designed for BMW differentials including the Z3 limited slip differential.
SAE 75W/140, API GL5, BMW, ZF TE-ML 05”

If no, witch oil do you guys suggest me?
Thanks in advance.

Well Subaru specify a 75W90 oil in most cases(what does your manual say?). You should be able to get SAF-XO 75W90 which should be correct. The standard turbo has a viscous differential and doesnt need an LS oil. Here they use 75W140 Castrol oil at some of the Subaru garages so I am not sure.
