sorry posted this in the wrong section, ill repost in correct section
Hey everyone new member here. So heres my situation. My neighbor has a 2020 mx5 with lsd and i usually do all his work on his cars and he asked me to get him fluid to do some maintenance on his car for him. i was looking up on alldata and Mazda says to use long life gear oil SG1 for the rear diff which says on the bottle online 75w85 GL4 , but does not list an alternative. I wanted to know if anyone has more info on this fluid and would it be safe to use a 75w90 say Valvoline synthetic or Mobil 1 as they are both locally available. but to my knowledge diffs would require a GL5 for hypoid gears.
