katana85

Hi guys, can I use the 80w90 instead of 75w85? It is becoming easier to find this oil instead of 75w85 or even 75w90? So far the brands that I found are ZIC (80w90), KIXX (80w90) and ACDelco (75w90). Any one have experience any of them? Note: I previously used 85w90 as per the shop that deals with OEM parts. But I found it getting black in the rear two days back, when I changed the wheel bearings. So, I don't want to use that oil again. Please advice me. Thanks,
