Can anyone tell me if I can use Full Synthetic oil in my 1998 EX Civic?

Is there any chances of leakage after using full Syn. oil?

Or only regular will be the right choice?

if regular oil has been working in the engine for the past 17 years, i see no reason to change it, why try to fix what isnt broken?

im sure that extra money would be better spent on, or saved up for other nessessary repairs/maintanence

It doesn't leak oil because of the oil type, it will leak with either oil type.

You should have no problems with it leaking oil unless you already have leakage.
