Oil leaks should never taken for granted. It might leak slowly now but the drain plug is at the bottom of the pan and any impact can further loosen the plug, which can cause it to drop off since the threads are not good.
Using an oversized drain plug is one way of doing it but you have to tap the hole to make the plug fit. Getting a longer drain plug with more threads to use the inner thread is another option, which is easier.
To avoid overtightening, always replace the drain plug washer.
