I live in Texas so the cold was definitely not the problem. I had my oil changed last week and I noticed that the oil level dropped slightly.
I took it back to the shop where they changed my oil to have them take a look. After further inspection, they noticed that they did not replace the washer on the drain plug. There was some leakage from this area. They told me that there's no way to check the oil pressure. That makes me wonder. I just now noticed that they put in 10W 30.
Hopefully it did not cause any serious damage. I have since not heard that noise since a couple of days ago.
