I have a 2005 dodge magnum and the oil light comes on when full and oil has just been changed. Is there a reset button that needs pushed?

Dash lights always get stuck or messed up- the most popular one is the check engine light.
You should call up all of the local repair shops and see either what to do yourself or how much they will charge to fix it, which shouldn't be much at all. Anyways, if you don't have an oil leak and it is full, the gauge light is just stuck. Same thing happened to my car.
