Hi guys,

I've searched but haven't found anything conclusive.

I'm looking to order some Subaru LSD oil, but have found two numbers. K0305Y0900 and K0318Y0000. Which is right?

I also noted that the K0305Y0900 is a straight 90 oil whereas K0318Y0000 is a 80W-90.

Is K0305Y0900 still available?

Certain threads suggests that K0318Y0000 superceeds the other oil, but they have different viscosities as stated above? So it's not really the same thing is it?

Has anyone used the "new" 80W-90 Subaru LSD oil in your plated rear diff?

Thanks for any help.

Regards
Errol

 

wouldnt mind knowing this also as im thinking about changing all fluids in my hawkeye WRX and cant find anything for diff oil.

 

new-age WRX simply uses std gear oil for the rear diff........

 

any recommendations? weight?
