The most basic and oldest fuel additive is alcohol. Alcohol will mix with small amounts of water and become an inferior, but combustible fuel, and it wont freeze like water.
Water often ends up in fuel tanks through poor handling and leaky storage tanks, all the way through the supply chain and could end up in your tank.
I have no first hand knowledge, but I suspect the gasoline storage and handling processes in Mexico could be a bit different than in the US, and the likelihood of contaminants higher in general. Something to deal with water might not be a bad idea occasionally. Of course you can buy the very same alcohol at the drugstore for $1 or less.
I also suspect that some costly chemicals and processes used in US fuel production may be missing south of the border. They may also have a high level of ethanol, which has been shown to damage fuel system components over time, at high percentages. I doubt any fuel additive can help that.
Deposits can take along time to get to where they become a problem. They can be growing all the time until the day they become bad enough to start causing a problem.
Generally, I think fuels have gotten better and deposits are less of a problem, but there are cases.
