Is my motor broken??
 

I was driving home in my old bug and it started cutting out as in loss of power. Then it was sputtering, and a friend driving behind me said there was alot of sparks coming out of the exhaust. I pulled into a gas station put in a little more gas since it was almost out, and noticed oil puddled under it. It won't start, it tries but it doesn't actually fire up. What do you think happened to it??
