more fuel to same air relative to stoich = rich condition

You are incorrect. ...
no
he is correct
and
his metro can run lean , when the 02 sensor is reporting rich condition
because of poor fuel quality - i have caused it by mistake and documented it

the EPA has also admitted that "some users" are reporting as much as a 20% difference in FE between summer and winter blends
