warming up a cold engine

What is the best way to warm up an engine in the wintertime to prevent excess wear? I've got 142,000 miles and im running mobile 10w-30. Thanks for the help!!!

It's to use an electric water- or oil heater before you start it. You can also use a thinner oil (under cold starts) like Mobil 1 0W-30 or 0W-40.

Where do you live? If NOrth like International Falls then a electric heater for your oil. But it depends Where you are.

im in chicago. It's usually in the mid to low teens in the morning during the winter

Electric heaters are worth using up to 5-10 degrees Celsius (40-50 F). Most heaters works by heating the coolant.
