In my experience  it's one of those things where it is technically not great thing to do, but in practice, especially with the products you've mentioned it isnt any real issue.     Products that can settle out are a different issue, but even most of those just in the tank aren't too much of a problem, but if you dont flush your lines and it settles out in them, it can get ugly.

That's been my experience,,but the usual disclaimer applies  "Your mileage may vary.. "
