Is 10W-30 Suitable for Cold Weather Use?
Can I use Mobil 1 High Mileage 10W-30 engine oil for my 100,000-mile car even though the manufacturer of my car recommends 5W-30? I did some research on the internet, and people seemed to say that whether to use 5W-30 or 10W-30 depends on where you live. If this is true, does Mobil 1 High Mileage 10W-30 oil have a limitation on cold weather temperature?
