oil dripping from engine but very very less in quatity. on 1998 Acura TL

There is a oil leakage from engine but very very small in quantity not dripping on bottom just engine body gets oily.
I bought this car for $.5000.00 in 2006 my car mechanic's opinion is don't spent on repair better check oil level every month regularly and top up if found needed.What should i do?.
