Plated LSD oil is one on its own, and you must use an oil designed for that purpose otherwise your diff will not work.

too much friction reduction will prevent the plates working.

mine has 85/140 in it i picked mine up in person from gripper diffs and they told me to use 80/140 but the difference in weight between 80 and 85 is to small to matter so 85/140 is fine and it is used in truck diffs and gearboxes

looking again on the opie site a lot of the lsd oil is 75w-140. lots of makes at reasonable prices.. although the motul is 42 quid a litre..
ill ring them tomoro to make sure.. cant see a lot of difference in 75w or 80w though so should be ok if they say so..

if u was in basingstoke id fill u up for free lol but 75/140 will be fine the difference from a 75 to an 80 or an 80 to an 85 is to small to worry about

yeah i thought as much.. and thanks for the offer shame ive got a month off work as i pass basingstoke on the way up.. ill most likely order some up tomoro .. hopefully it wont be the motul 40 quid a litre stuff they recomend.. ive used redline stuff before and had no problems but they do castrol in the same grade too so a few to choose from...
thanks for the help..
