This is a really dumb question but I own a 1992 Acura Vigor and 02 Accord.

The Vigors owners manual says nothing about replacing the differential fluid, but upon finding out in an Acura forum that the Vigor does have this. So with about 130k miles, I changed it for the first time. It was gross, dark, dark black sludge and smelled really bad. So I pumped the new (very clear)gear oil in and I'm good to go. Why is this not stated anywhere to be changed?

Main Question: Does my 2002 Honda Accord 4cyl have this?? It's not stated anywhere in the owners manual to be changed.

Thanks everyone.
