Idle vs Engine Restart?
I deliver pizzas part time and have been doing so for years. I have always thought that leaving the car idle instead of killing the engine when I run to someone's door was the best route. Since I got my Honda I have noticed that it drops my MPG by a LOT just idling for the 2-3 minutes per stop. I always kill the engine when I go to a bad area/apartment complex, but if I go to a neighborhood and park right outside the house I leave it running so I can jump in and go.
I figured this accomplished a few things:
Less wear and tear on the battery, starter, and smaller amount of gas used (idle vs STARTING motor)
My question is if this logic if flawed in anyway.
On a side note, with the proximity/push button start if I leave the car with the key fob in my pocket will it stay running? Can I lock the car with it running using the key fob?
