So recently especially in the mornings, like 6am. When i start my car to go to work, the check oil light comes on, but as soon as i start driving it turns off. This happens even when i just put oil in the day before. Could it be the cold weather? it's about...i'd say 40-45F around 6am. What else could possibly be wrong?

 

when the light comes on i'm assuming your checking to make sure there is enough oil in there.
Could be a faulty sensor, take it to the dealer and have them check it.
