Figured i'd share this link with you. A used oil analysis is something that everyone should do at least once (being that this is in the 92-00 civic section). It only costs 35 bucks and will provide you with invaluable information on what's going on inside your motor. Here is a link explaining how Blackstone Labs breaks down and tests your oil. Cheers, Jeff.
