It's not pure crap, just have some effect, but rather good or bad..

For car power,
If max, compressor always running, so car loose power a bit
If low, the car will have a bit more power when the compressor OFF.
If aircond off, the car will have the power without the drag from compressor.

For lifetime of compressor, i heard 2 versions.
Version1) If MAX, the compressor can tahan longer because the compressor didn't ON and OFF so many times.
Version2) If MAX, since the compressor running at all time, then mati cepat.

So, for me, i never care which 1 last longer or good or bad..
Just use how it is designed for..

When u are hot, then put to MAX lor, if u want lower temperature, then put to LOW lor, if u are too cold, or climb hill, then OFF aircond lor... simple enuff...

but what i practice is, when starting the car, the aircond is OFF.
