Hehehe, sorry for my ignorance...ano po yung cat con?

Cat con reduces emissions but SUPPOSEDLY harmed by high ZDDP. Since you don't have cat con, you don't have to worry about your zinc levels unless it harms other parts. Let's wait for the gurus to verify this. Kung wala naming nasisirang ibang parts like cat con yung high ZDDP, you don't have to worry about it.

we didn't have catalytic converters on civics until 2001.
