To bump or key start?
I've been doing some engine off coasting lately and i was thinking if it's better to just start the car using the starter(key) when the light turns green (and i'm at the dead stop) or bump start it at about 20mph before i get to that red light.
I decided that idling for that 5-10 seconds (after the bump start) coming to a full stop, then another 5-15 seconds at the light before it turns green is not worth wasting fuel.
But i figured it will cost me about $100 to replace a starter, and assuming it will give me about 7000 starts, that's about $0.014 per start. Idling for about 30 seconds costs me about $0.012 so it's about the same if i'm sitting at the light for 30 seconds. if the light turn green just before i get to a stop i should have just bump started it.
Does this sound right?
