Jeff, Mobile 1 is available in theses weights:  0w50, 5w50, 10w50, 15w50, and 20w50 ask NAPA to get whichever one suits your conditions.  The first number is for starting the engine in cold weather.  The second number, 50, is for running the engine once warm.  Once warmed up the engine does not know what temperature it is outside.  It needs 50 weight oil.  If you had a block heater or a heated garage then none of this is relevant, use 20w50 or 15w50
