Early Hawkeye Diff oil question
 

Evening all,

Could one of the transmission gurus please tell me what is the correct grade and quantity of oil for my 55 plate Hawkeye STI?
I have read quite alot about specific LSD grades being used and would like do an oil change to ensure i have the correct grade.

Thanks

90LS grade oil, not 75w-90 as that's the wrong stuff

I use mineral oil 90LS one, you have to change it more often but its possibly better
