<div dir="ltr" data-setdir="false">Hi - if you are running a Quaife, the Redline should be okay. The only reason it would not be okay would be if you were still running the stock differential center section which has brass / bronze (aka "yellow metal") parts. The shockproof stuff is API GL5 and that will eat the yellow metal. But the Quaife internals are all steel, so GL5 should not be a problem.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">As a point of reference and pertaining to the question, I've been mostly using Mobil 1 75w140. I would also recommend using the higher numbered oil 75w-140 vs 75w-90 because the differential runs very hot and I think the 75w-90 would be working out of temp range.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Regards,</div><div dir="ltr" data-setdir="false">Bob Lang<br></div><div><br></div>
