2000 Ford Mustang My Poor Car

You need to find that leak asap! You should start by wiping clean under the car. Clean it enough so that you can tell what is fresh oil and old. Second of all. Check the coolant for signs of oil. You need to determine whether its leaking or being burned up. You can slide a piece of cardboard, if you have some, under the engine. If its leaking down you should be able to see where and then go from there as far as repairs. Does the car sound normal and the pressure go back to normal when the oil level is right? When its low, what kind of noise does it make? Does it tap or rattle or what? Does the sound change when you rev the engine a little? Repost here when you find something out.
