As the weather starts to drop this weekend, Sarah wants to know: How long should you let your car warm up in the winter?
Mechanics say anywhere from 5 to 10 minutes is ideal. Letting your car idle for 15 minutes or more is just wasting gas.
Car guy Gordy Leach has a trick during extremely cold days: After your car is warmed up, put it in reverse or drive, and then keep your foot on the brake for 20 seconds before moving. This helps the transmission warm up too and cuts down on wear and tear.
