Yes, do-it-yourselfers do this a lot, but I've seen experienced mechanics do the same thing, including one who still refuses to believe this is an issue. There are "mechanics" out there who think a failing brake master cylinder can be repaired by adding power steering fluid to the brake fluid! We don't assume anything any more, which is why we always include these warning comments. Please don't take offense. We also know that most mechanics know these things already.
