Today’s modern cars are ready to go in cold temperatures without excessive idling, says the Car Care Council.
“Unless you are trying to defrost the windshield or warm the interior of your car, idling “is not required” for today’s vehicles,” said Rich White, executive director of Car Care Council. “In most cases, idling longer than 30 seconds is unnecessary. The best way to warm up your car’s engine is to drive gently at the start. Remember, also, a vehicle gets zero miles per gallon at idle. The result is lower fuel economy and wasted money.
