Aldo, on all of the common Briggs engines you measure the oil by screwing the dipstick all the way in. On all the Honda and Kohler engines I know of, you just rest the dipstick on the top of its thread - see here:

It rather reminds me of the way car auto trans selectors worked prior to Ralph Nader and his book "Unsafe At Any Speed": Ford had the PRNDL that we all know and love, GM had reverse all the way down, beside low, and Chrysler had a weird typewriter gadget. So now we have federal legislation requiring everyone to use PRNDL. The moral of the story is, if the manufacturers don't get it right on their own, someone will eventually do it for them.
