I have a 2004 lexus es330 leaking some oil. It is not a lot. I was going to use Lucas Oil stop leak. However, I am scared to do that because I do not want to break my car. What are your thoughts?

+1. Without a diagnosis, you'd just be playing a game of guess-and-check. There are ways to find the source of a leak - for instance:

I would try to find out where it is leaking so you know your options. Stop leaks will not ruin your car/engine, all they do is soften/expand the seals/gasket to stop or lessen the leak over time. The Lucas one you have to put a lot of it in your engine so I would do it after a oil change and not put as much oil in it to make room for it or else you are going to have to drain a little oil with the Lucas.
