Quick Diff Oil Question:

I'm meaning to change my diff oil amongst other fluids, I was offered a big big new bottle EP GL4 80w90 oil today. I think the diff is said to take sae90 - will the 80w90 be suitable?

Much obliged,
Matt

80W/90 GL4 should be fine; 80W is the cold viscosity but the oil soon will rack up to SAE 90 as the gears warm up.
