If you truly require the auto to keep running with the AC on in summers, maintain providing revs to the automobile to make sure that the engine runs more and also oil circulates inside the engine. Considering that India is a highly damp countryside, AC is always on, yet try using it less typically given that it puts pressure on the car parts as well as you intend to extend the life of your automobile don't you?
However today, you do not require to do that! The idling you do on today's vehicle burns precious fuel as well as leaves gas deposit on the cyndrical tube wall surfaces that stay with it since the cyndrical tubes aren't moving as quickly as they normally do. This contaminates the engine oil with carbon deposit and makes your car's innards filthy.
