That's less than a pub measure of spirits!

What pub do you drink in?!

(20cl is about a third of a pint)

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!

If 20cl is less than a measure (of spirits) I want to visit your pub!

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?

They are, but come the end of the season you can be left with fuel sitting in the tank and lines for 4 months. Also it’s unlikely petrol mower manufacturers have been as diligent as car manufacturers at ensuring their various hoses and seals aren’t attacked by the ethanol.

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.

My Honda Izy is a 4-stroke and Honda say all their petrol lawnmowers manufactured for the UK market since 1993 are fine on E10 petrol.

My mower is electric [cordless] - has been for the last few years.
