Yep, I am in the IT business and re-starting hardware regularly is bad, big time.

But how much difference does it actually make? Difficult to quantify I suppose because it depends on how long you are standing still for. However, I am convinced that S/S is not efficient if it switches off for a few seconds only. There is a lot of unused fuel going through an engine on startup.

Bit like a neon light which needs to be switched of for something like an hour before it becomes more efficient than leaving on. Interesting subject, I wonder what the break even point for an engine is?
