I wouldn't call what Shouty's fuel economy discussion in this video "calculations"... it's more like he decided to knock stop/start technology and then just made the numbers fit. I don't like Shouty's videos when he gets into questions like this. He seems mostly to fire from the hip when it comes to anything fuel economy or engineering related. Where I like him is on questions of repair and maintanence.

The Engineering Explained vid is considerably more persuasive as far as calculations.

Also, I am driving a 1998 Civic that I bought in June 2001. It has 260,000 miles and still has the same rods and bearings and piston rings... same 1998 starter. But for the last 90,000 miles I have been stop/starting it maybe 10 times a day.

Just one person's experience... but I think the hardware is a lot more durable that he is claiming.

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
