check oil light
 

I have a 2000 STS and the check oil light came on, had to add a few quarts and level now is fine. When starting still shows check oil. any ideas??

the sensor in the pan is sticking when oil is warm it loosens up
either replace it or take it out next oil change and clean it

Thanks, I will have the shop do it when I take it in for the normal oil change.
