Warren's Coastal GL-5 Gear Oil says "Limited Slip applications for top-off only." which indicates a minimal or no amount of LS additives. It has EP additives of course or it wouldn't pass GL-5.
I might actually look at this Coastal 75W90 dino for my Subaru's gearbox, because it requires GL-5 due to the hypoid front diff residing inside the gearbox but don't really want LS friction modifiers in the gearbox.

The owners manual specs 75w90 GL-4 OR GL-5. Someone here mentioned the factory fill was GL5 75w90, and it pretty much works the best in this application, dino, not synthetic
So, can anyone suggest a DINO 75w-90 GL5 that isnt overly additized with limited slip additives? Would a plain jane napa or coastal fluid work? Or I think I saw valvoline having one too...
