Hello guys,
As subject..
Is there anyone use this differential oil for differential and manual transmission?

Ive been looking a few data and opinion that this oil can be used in manual transmission but seems no peace of mind if using this oil in manual transmission.

Is this oil fully synthetic or just mineral base?

I already use this oil in my differential and i wanna ask ur opinion that is this oil can be use in heavy duty? Or just light duty? Because i always full load of shop things or sometimes carry on 8 people and hauling a lot..
I am quite afraid of damaging the axle gear.

GL-5 means HD, but if your transmission has brass/yellow metal parts, you will want to stick with GL-4 gear oil, check your owner's manual.

HD means High Duty, right?
My own manual tells use GL4 for the transmission but ive been searching the fact that in RX8 this oil also can be used for transmission..yeah but still debating pro and contra..
