Hi, I have a 2000 Neon. It has 256,000+ miles and runs great. My immediate issue

What is your question?

My immediate issue is it eats up 3 quarts of oil per month. I don't see much smoke coming out of the exhaust, only if it idles like waiting to pick up daughter. I see a tiny drip by the oil pan. Is it ok to use that stop leak you add to your oil? It has a lot of miles so do not want to put too much money into it but it looks like new. SO, my question is, should I replace the oil pan,which I am not a mechanic and never done anything like this, or would it hurt anything just to add 2-3 quarts of oil per month? Oh, I have same issue as others with the water leaks in the rear floorboard and trunk and have used silicon which helped for a bit but always comes back. Ty for any help and advice and if there is a recall on the water leak problem. -Phil
