Esso was/is the world wide trade mark of Standard Oil of NJ, which in 1970 or so renamed itself "Exxon". This was largely due to the fact that, going back to the break-up of the old "Standard Oil" before World War 1, each of the newly formed "Standard Oil" companies had the right to use the name "Standard Oil" only in its home region. "Esso" was the phoenetic spelling of "S. O.", or "Standard Oil", so Standard Oil of NJ could not use this trade mark everywhere in the USA. In the 1960s, in some parts of the country they were "Esso", in the west they were "Enco", and in Texas they were "Humble".
In any event, none of this nonsense pertained to their outside of USA operations, and what is now Exxon-Mobil continues to use the "Esso" trademark throughout the world.
So, getting back to the topic of the motor oil, this is motor oil made by an Exxon-Mobil affiliate outside the USA. I have some Esso ATF, and it was made in Canada.
