Living in a cold winter climate like Calgary, Alberta. Canada where we have just been through a very cold spell where many people could not start their vehicles including me. I am going to do an oil change tomorrow which Mobil 1 Oil should I use 0W30 or 5W30. I have an older vehicle.
Thanks in advance Denny B
Without knowing what car/truck you have one could say 5W30..! However to be more accurate, would you please tell us what vehicle you plan to do the oil change on..? Or, you could check
I'd use the 0W30. Once the oil warms to operating temperature, it will be almost the same as the 5W30, and when it is cold it will flow much better.

Thanks Denny
However to be
Does the weight make a difference in just STARTING a car? The lower weight would mainly reduce damage from extremely cold starts.
If it is an 1981 Farimont, it is likely that the seals are already leaking. I think the idea that synthetic oil can casue problems with seals and gasket is overblown. However, if you are really worried Mobil now has a "high mileage" formula syntehtic blend oil that claims to condition seals to reduce leakage.
