The idea of idling before driving dates back to when cars were built with carburetors. With new fuel-injection technology, complex computer systems and thinner synthetic oils, drivers don’t need to warm up their cars before hitting the road. 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, a vehicle gets zero miles per gallon when idling and the result is lower fuel economy and wasted money.
