Oily oil pan

[K8G_BLK]

I did my first oil change since buying my 21 with 54,000 miles (bought last November) yesterday and noticed the oil pan was quite...oily. I didn't notice at the time, but looking at the pictures now, could the drain plug not have been tightened properly have caused this? It should be turned all the way to the tabs, right? The oil level was fine on the dipstick. I'm thinking I should just clean it and see if it get oily again now that I know the drain plug is back on properly.

Also, my used oil smelled like gas, a lot. Is that normal?

Someone please correct me if I'm wrong, but I was under the impression that Ford plastic drain plugs are one time use, meaning a new one should be installed when doing an oil change.

As far as gas in oil smell, how long was the previous oil used? Excessive idling, short drives? Both can lead to the oil not getting hot enough to burn away moisture and fuel.
