  • Oil isn’t the problem, my car will turn on again before too much oil drains out of the engine and oil pressure sinks too low. Cooling is, interstingly, so they switched to an electric water pump for cooling - it will stay running during auto off so you don’t get too hot temperatures in the turbo for example. (4cyl 2l engine has a turbo)

    There’s quite a bit of tech going into auto off since it first appeared. (Heh, my first car in 1989 had an aftermarket start stop switch to stop the engine at the traffic light - i never used it except once or twice for fun - still one cylinder exploded one day on the Autobahn)

    Depends very much on the car. My car has auto off and starts up the engine as soon as the car in front of me starts moving (it detects that with the parking and radar sensors).

    Or if I just move the foot off the braking pedal the engine will be fully running as soon as my foot reaches the gas pedal.

    It’s at 2017 Mercedes, at the time they already spent some effort into that tech, for example I have an electrical water pump that keeps up the circulation even during auto off and the starter is different so it can start the car even while starting to move.

    The only moment I turn it off (ok switch to sport mode which turns autostop off) is when I want to race someone at the light in order to change lanes in front of them later.

    I normal operation you don’t notice.

    Ah and last year autostop did not work for a few months as my battery was old, the car noticed and refrained from stopping the engine until I got a new battery (It will also do if I need aircon or the motor is too cold or a number of other conditions)


















  • Ok, but please DO NOT EVER go down to pure energy. Last time I did this, my experiment exploded, now it takes a whole lotta space, complex atoms and life and all the shit along with more or less intelligence. I’d feel really bad to shut it all down now, so I let it just run on its own.
