Category talk:Non-petroleum based lubricants

If there already exists a category for Petroleum based lubricants then all others are implicitly the opposite, there is no need for this category. Its as if one started to create categories for things people/things aren't, i.e. Non-American people, Non-convicted politicians, Non-cartoon programs, etc.
