Seriously...how can anyone answer this question? The crap's made in
China, right?
What do you suggest, replacing them when they fail?

Without sending sample out for chemical analysis there is no way to know
when your oil needs to be replaced. But you probably do it regularly.
Same idea.


Exactly, change them regularly, but even better have a shut off valve for
the washer supply and turn it off when not in use.
