What do you think about it for a Porsche? Thanks

First, you need a new mechanic; he is dead wrong as well as a “poster child” for what is wrong with the automotive repair industry. Brake fluid is hydroscopic; it absorbs water from the air and retains it, reducing the boiling point of the fluid and its ability to stop the car. The water also corrodes the Hell out of little items like your ABS/PSM system, causing thousands of dollars worth of damage.

The fluid should be flushed and changed at least every two years, more frequently if you track the car.........
