That is bad advice. Here is why...
Let's say you have been using ETH free fuel every fill up. And then go on a trip. Along the way it's highly likely you would fill up with E10 because of availability.
Now you have introduced E10 fuel into a fuel system that has been exclusively using non-ethanol gasoline. That ethanol, as a new solvent, will tend to dissolve and loosen deposits that have become present in the tank and fuel system over time. This surface cleaning action removes that built up gunk and leads to clogging of the fuel filter and injectors. That was an actual widespread problem when E10 was first being rolled out. Many people had serious problems with their vehicles. Luckily, the modern fuel systems no longer use rubber gaskets, which was another nightmare by itself.
Second, ETH free fuel is about $1 per gallon more expensive than E10. One quart of stabil is about $10, and will treat many tanks full of fuel. Significantly less expensive overall, and superior protection.
Third, when on a trip, there's no need to take stabil since you will consume all the fuel you are buying in a short time span. When you get home, then add stabil. No worries about some fuel in the tank remains unused for months.
