Depends on where you are.   What is the ambient temperature where you are
at when it happens.
You may need to change the oil to a lighter weight.   I used to change it
to 10w-30 about this time
of year and change back to 20w-50 for the warmer months in early March..

If the ambient temp is warmer than say 30 + F  then it's probably not an
oil weight problem.
