I have a 2005 chevy cavalier. I was riding around with very little oil if any and on a terrible tire that made my whole car shake! After a few times driving It like that I started hearing a rattling noise in my dash. I parked it and now it will not start. It tries to start but the entire motor shakes hard and it makes the initial start up sounds but wont completely turn over to start it.... everything inside still works.. ie radio, air, lights ect.

My dad put a quart of oil in it. And that was the last it started.... was it the wrong oil (it was harley davidson oil im assuming it was ok) did I rattle something loose? Any suggestions? I really need to get my car up and running - is it the brains or a coil maybe

Answer: Well if the engine on your Chevy was that low on oil and it stated making noise and rattling, i would have to guess that the engine is damaged. An engine cannot operate properly without oil.

The wrong oil would not help or hurt the fact that you have major engine damage. It's too late for that.

If you knew it had no oil in it, why did you drive it "a few times" ?

You are going to have to have a mechanic look at it. He will do a compression check, oil pressure test, spark and fuel pressure check to see why it will not start. My guess is that the engine is blown and you need a new one.
