"MB strongly advises
that there is no application for distilled water in the car, and that
includes the windshield washer and hosing off insect remains. "

"Pure, distilled or deionized water is extremely bad for aluminum
radiators, as was detailed in an MB technical note many years ago.
Distilled water is demineralized, and it wants to be mineralized, badly.
It will take the mineral right out of your radiator, leaving holes.

Tap water is much preferred, and even better is creek water, with
particulate material filtered. There is some thought that mixing the
distilled water with antifreeze will satisfy the mineralization content,
but that is only a thought, and it may depend on the level of impurity
of the antifreeze, which could be highly variable. MB strongly advises
that there is no application for distilled water in the car, and that
includes the windshield washer and hosing off insect remains."
