If you actually need the automobile to keep running with the Air Conditioner on in summer seasons, keep giving revs to the automobile so that the engine runs more and oil distributes inside the engine. Since India is a very humid country, Air Conditioning is constantly on, but try using it much less commonly given that it puts pressure on the automobile parts and also you wish to extend the life of your car don't you?
While quiting at a traffic signal, you must have noticed that if the rush is also considerably, some people closed off their automobile engines and rest back silently. No, they are not stupid! They are actually providing even more life to their car. Unnecessary idling kills your auto gradually without you also knowing it!
