I thought i would open up this thread again. Are people able to update on their experiences of acceptable or proven bevel box oil brands and specifications. It would be helpful to know your local climate as well.
I have been using Red Line Heavy Shockproof Gear Oil 75W-140 this year, filled to the orange breather, it did seem to make the bevel box quieter. Most of my driving around southern UK. A trip into Europe when it was 32C did seem to create more noise from the bevel box though.
