For some reason a lot of people believe that idling is somehow good for the engine.

In my 1972 Super Beetle owner's manual I had it specifically said to not idle as much as possible. Idling doesn't do anything good.

Unless you live in the cold and want your interior of your vehicle warmed up for you. Back in the old days of carburetors the engine would also be less responsive and more likely to die when cold.

But in warmer climates, especially with fuel injection, idling is like buying gasoline but putting it into your oil and filling your engine with carbon deposits at the same time.
