I'm interested in this too. Spoke to Opie last week and wasn't convinced when they said to use the same fluid for everything. The manual gives different specs for them. Wasn't sure if the guy was flannelling me TBH

its perfect....ford oil spec is for std cars...not tuned ones producing lots of heat....
ive done 50k miles on fully synthetic 75\90 ,and its spot on.
bara, who builds the mullit box told me to never use anything else in them...theres hundreds of us using it....
its one of those once you use it, you think why havent i done this earlier
an example, front diff oil, normally when drained is black, burnt, stinks....weve all seen it!
with fully synthetic 75\90 in it, after 50k miles its still clean, not burnt, and smells fresh as the day i put it in!

Front diff needs bottom plate removed to change oil think rear diff has to have back plate removed. think i'll try 75/90 oil as well.

how does this oil effect gear change when cold as i think it may be thicker than original ford oil and does it really make that much difference. only problem i will have is my gbox will fuck up before i get real benefit from the oil as will have around 475 horses
