That's less than a pub measure of spirits!

Back on subject:

The primary route for water contamination in fuels was determined to be via condensation in fuel tanks, not by simple contact with damp air. The droplets would sink to the bottom of the tank and be absorbed by the ethanol as it broke down by phase separation, which could take weeks or months, depending on conditions.

According to CSP (https://www.cspdailynews.com/fuels/3...ase-separation) it only takes 40 gallons of water in 10,000 gallons of E10 to cause phase separation. That's 250:1, so in a 50 litre Logan fuel tank, just 20cl of water would do it.

That's less than a pub measure of spirits!

When it comes to petrol garden equipment, E5 is the prefered fuel.

Ethanol strips oil in 2-stroke engines, I have been told. So they tend to run dry and get a lot of wear. But are most 4-stroke these days?

Plus, if you use a petrol mower chances are you have other petrol tools, and these invariably use 2-stroke engines. So unless you want to keep two cans sitting around you might as well put premium in everything.
