Hi guys

I got some Liqui Moly 75W90 GL5 oil for my gearbox change. I see on the american site, that you can use this same oil in the rear diff.

Is this ok?

How long is this synthetic oil good for in the gearbox? 100 000kms?

P.S for got to say I have a 2004 STI.

personally i would use a specific LS rear diff oil..............

honeybadger

I know. Right?

This must be a GL5 specification, I'm sure. The owner's manual really is sh|t. It shows all the possible oils and their heat ranges, but recommends nothing.

Do you know the viscosity of the LSD oil the STI wants? is it a 80W90 GL5?

just me
