What would cause rough noisy idle, gas smell in oil and exhaust

yes, it did run out fast and almost seem to have more oil than usual. Very thin, but did not notice black smoke. However, I did notice small amount of water coming from exhaust pipe. I had tried to take it in to get diagnostic codes last Saturday (didn't make it). When driving it, it was extremely loud, didn't want to shift gears and when I pushed in the clutch it sounded like the engine was reving up. Didn't have enough power to get up my driveway (hill). After replacing the battery it seemed a little stronger and was able to get it up hill. Hoping I won't have trouble getting it to autozone today.

You stated taking it to a shop not zone. The shop is where it needs to go!

thank you I will post codes once I have them
