I briefly read a response to an unrelated post the other day, where someone wrote you don't need to use the glow plugs once the car is warmed up and run after the initial start. If that's true, it'd be best I don't use them, as I guess they wear out after a while. I'm in Atlanta, it doesn't get that cold here anyways, but I guess the less I use the glow plugs, the longer they'll last.

What's your take on this?
