Diesel vs Petrol

This January I bought Ford Figo diesel version. I exchanged my old Maruti 800. Before that I always thought nobody loves a machine. 

This summer was pretty hot. AC is no longer a luxury – it is a necessity. We have a window AC in the bed room and a split AC in the dining. The window AC is the aged one – bit noisy but works without complain. One day, it was bed time for RIch. I was trying to make him sleep. After some time I thought that he had fallen asleep. When i just rose to leave, he opened his eyes and said –

“You know Dad-Dad, window AC runs with diesel and split AC with petrol”
