Make sure you have the right oil weight, if that checks then it could be a bad oil light switch or you indeed have an oil pressure problem. Best to do a manual oil pressure check, if the pressure is low at idle but jumps up to normal at slightly higher engine speed then you may well have excessive bearing clearances inside the engine. Now going a heavier weight oil may help but only for a while, so it’s either engine repair or get rid of it while it’s still running.


Could be oil pressure sending unit, or a loose oil cap are the 1st 2 things that come to mind....or it could be that it registered full before starting and then filled the filter to register low
