Only on a few newer engineering snafu's. Euro's ran into trouble keeping a lid on approved fluids and over selling cars with too few service centers. Toyota outside of what would be a minor design flaw, also didn't "Americanize" their design, nor spec the schedule properly.
You don't see any Chevy or Ford ..or Chrysler (save the 2.7) sludge monsters, do you?
