Oil Change (Back to Stock)

[Steve]

Gents,

At one point I switched to GL-5 for the wheel reduction units and now I'd like to go back to GL-4.

Will this create any problems?

Thanks,

No problem to run GL-4, but most run GL-5 in the hub reduction units. The transmission is the only component that requires GL-4(Redline MT90 is also acceptable fir the trans).

[Steve]

Thank you, Sir. Is GL-5 used because GL -4 is so scarce these days?
