If it actually gets cold then 5w30. The reason for lighter warm oil weights is mostly to improve fuel economy. The e36 M3 called for 10w50 b/c M3 owners don't care about mileage but they do care about their engine. It also called for a long warm up period before hard driving. Point being, if you are willing to wait for the engine to warm up and you don't care about mileage you could run 10w40 if you wanted to. If you drive short distances you may want to go with 5w30 b/c your trip to the store will be over before the car had a chance to warm up. If you drive more than 10 miles one way then 10w30 should be fine. 5w30 will not cause a leak, however if the car was originally run with mostly natural oil and then later in it's life switched to synthetics the gaskets may change shape/shrink/expand, and cause a leak. If you like Mobile 1 stick with it.

Well, the Mazda motors are built really tight. In the winter (below 30 degrees) I would stick with the 5W30. When you get over 200K on it, switch to 10W30. Good luck.

5w30. For a 4 cylinder in winter works well. Synthetic is good but not necessary.

It depends upon the lowest winter temperature you expect. For really cold winter temperatures, use the 5W30. Ask the Mazda dealer in your area. (5W30 will NOT cause an oil leak.)

The weight ratings are as follows: The number before the 'W' is the vescosity of the oil when warm, the number after the W is the vescosity when it is cold.
Your question failed to include the region/area you live in, the temps you experience during winter, and the vehicle you drive. The best thing to do is to consult your vehicle's owners manual for their suggested Oil for winter. Many newer cars are calling for a 5W20 for winter, but check your owners manual for your car.

I have a 200,000 mile 1991 SAAB. I use Mobil one 0W-40 all year long. Starts at 20 below zero.

5w-30 for winter and 10w-30 for summer.
