My 95 Ford Escort Wagon stalls. Only once the car is up to running temp. Also noticed an oil leak. Help me!

Had recently filled the tank, started the car and it ran really rough. Thought maybe some water or something in the fuel line cause it resolved a few minutes later. Car was past due for oil change so changed it. Noticed not a lot of oil came out and of course it was really dirty. Put in an oil additive and a fuel additive. Still stalling but only once the car is up to running temp. Dad says to try a can of dry gas. Another guy says I may have ?? thrown a rod?? Does anyone have any ideas? I have not been driving it and have noticed it has a little puddle of oil underneath. I can’t afford to put a lot of money into this car.
OK – So far it sounds like I should just get another car. Coincidentally, I was just offered a 98 Camry for a steal. Is it worth trying to fix the Escort to sell it? I can’t sell it as it, can I?
