I usually get mine for here, www.opieoils.co.uk the guy posts on here to usually has some decent deals on oil going to need possibly 2 litres as im sure its 1.1l for the rear diff

the R180 rear diff only requires approx 0.8ltrs and the LS oil is exactly what you require
90PA Motul can also be used but not the only one.........

we carry an extensive range of Motul & Millers oils in stock and have the specific experience to back up your purchase

millers 80-90 crx Ls 80-90 is needed

90 PA is a mineral based oil, CRX 80w90 LS is semi-synth and CRX 75w90 LS is full synth

all are perfectly compatible with LSD rear diffs........

not doubting you high knowledge but would a mineral or semi synthetic be better in a lsd diff rather than a fully in your opinion ?

no, all are perfectly useable

in most cases and particuarly where high competition type loads are invloved the race spec full synth oil will be our choice everytime..............albeit in a different grade again (75w140 LS)

its the "LS" additive that your looking for and IMO a lot of 'myths' abound about synthetic gear oils that we dont find in practise, but then again what would i know - only been involved in Subaru's for 15yrs+ and before that various other competition vehicles (including m/bikes)
