Jason Miller Quick Answer: For most passenger cars, 6-gauge or 4-gauge jumper cables handle the job well. Trucks, SUVs, and diesel engines usually need heavier 2-gauge or 1-gauge cables for enough cranking power.

Knowing how to use jumper cables correctly turns a stressful roadside moment into a five-minute fix, as long as you follow the right order and keep a few…
