    gear oil question

    I want to change the front & back gear oil on my 80 gs1000g. The book calls for 80 w with a GL-5 rating . I have 80 w 90 . Is that ok ? Just want to make sure !
    thanks as always !

        When i changed mine I switched to Mobil 1 synthetic 75W90 and didn't even use a full quart between the gearbox and rear differential.

          Use an 80W-90 or similar gear oil rated for hypoid applications. The stuff your supermarket sells for car differentials.

          Don't use engine oil, otherwise just about anything intended for the application will be fine.
