Hi, we have got a 99 Discovery 2, V8i - LPG, we have just changed the transfer box oil & front & rear diff box oils and we have used Rock Oil 5/30 fully synthetic oil which we had very highly recommended to us.
Now a bit worried if this is this as good at the 75/90 that is usually recommended???
Any thoughts please?????
