I think the point is that it’s possible, in theory, maybe depending on your employer. But you get close to that amount of vacation time in total. The majority of Americans don’t get more than two weeks for the entire year, and many get none at all, only sick time. Many Americans can’t even take just two consecutive weeks off any time of the year.

You’re thinking of the Space Force.

SPACECOM is a unified command that has its origins in the 1980s. It is entirely necessary and handles real things including military satellites and missile defense.

That might be true, I’m not a mechanical engineer but despite that, my understanding is that within the engine block itself, cylinders are primarily lubricated via the system holding pressure. This pressure starts to drop the second the engine ceases.

You can notice the effect on cars that have realtime oil temp monitors. Mine does, and it’s digital. My stable oil temp is around 216 degrees Fahrenheit. After a start-stop cycle, even for only 5-10 seconds or so, the temp drops about 5-8 degrees. After a minute, the temp is down 25 degrees. That’s significant. Essentially the engine is no longer “at temp” for the first 30 seconds or so after it resumes. That’s 30 seconds of additional semi-cold, under pressure wear each cycle.

What about the fact that the oil drains to the pan in those few seconds that the engine is stopped?

This is my real concern. Sure you can upgrade starter motors and batteries to handle the extra cycles, but you can’t do anything about increased scoring and wear on cylinders in the milliseconds before the fluids start to circulate again.
