Our mechanic suggests shell rotella (diesel) formula.  even though engine is not diesel.  says for 1992, this was recommended.  also he recommends to avoid synthetic oil.

If you already have a leak - it will leak even faster with Synthetic because it is a thinner oil. His suggestion might be a temporary lessening of the problem - but it will definitely not fix it. Only a new seal and/or pump will resolve your issue.
