Just a quicky, but what engine oil does everyone recommend for my '92 69k saph coss 4x4 , as i can get silkolene fully synthetic, to the same grade and spec as what ford recommend, at very good price.

Also what diff oil (spec/grade)

and Gearbox oil for the MT75?

Any help greatly appreciated!!!

P.S i have a technicians manual on it's way soon, but thought i would ask anyway!!!!
