Which oil viscosity to use regarding the temperature under the car hood?

Why should i consider the outer temperature 10C.25C or 32C when in machine bay the temperatures are much higher.And then the motor operating temperature get about 100C...Which oil viscosity to use regarding the temperature under the car hood?
my answer is try to check it out first on auto repair shop..Which oil viscosity to use regarding the temperature under the car hood?
Almost all the oil used today is a multi viscosity oil like 10W30 which means when the oil temp is cold it will get no thicker than a 30 and when hot it will get no thinner than a 10 rating. Your engine may run around normal temp of 160 or more but the problem is cold start up when the oil is thick so in colder climate you may need to run a thinner oil your local shop should be able to advise you of an oil that is right for your car and climate.
What kind of car is this?????? I use only Mobil One 0w-30 or 0w-40, depending on what the owner's manual says. THis will improve your performance and return the best MPG's under ALL temperatures!!!!
