Differential Oil

[M30]

I am planing to change the oil in my diff on my E23. What oil would be recomanded to be filled in the diff. The thing is that i also have 2 bottles of oil at home which was suppost to be used in my Land Rover but i sold the car before i could change the oil. One of them is a Esso SAE 140 and the other one is a Castrol EP 90. Is the multigrade better?

Bros,

How often should you change the diff oil?
No service book la...

Esso SAE 140 should be a lot thicker then Castrol EP 90.

I have mixed oil before too, to get the in-between viscocity... .

I normally change every 20,000km, but a lot of ppl didn't give much priority to the diff oil and can sometimes kept using till it goes past the 100,000km mark.

use the 140.

I did not know have to service that often...but the last time my mech told me my oil is still ok but thought of changing to clear the oil stock in my house. What is the ratio u mix?

use the 140.

I have been using Q8 Fully Syn 75W90 and sometimes mixed with Q8 mineral 85W140... 90 should be sufficient...
try the 140 if you have stock... you might like it better since it's thicker and may suit the old diff... However, if it doesn't fit right, either drain it and use thinner diff oil or mix some of the thinner oil...

that's what i said.. use the the 140. the 140 is thick. what do you have to loose ?
noisy diff or a worn bearing ?
