I agree Rob. E0 would be better in any vehicle. Are you going to try this yourself?

Really interesting video.
One point he made at the end which I think is worth bearing in mind:
Ethanol contains an octane booster (he says it’s 100 -113) so in removing the rotten stuff you are also reducing the octane content of the ethanol free petrol you’re drawing off.
I’ll let someone better at maths than me work out how much the octane rating of say E5 petrol is reduced by removing the ethanol.

E5 means 5%? So an octane of lets say 100 would become 95. I think. Then again, thinking isn't my strong point.

I made a spreadsheet to calculate the resulting octane level.
Overall Octane 99 Ethanol Octane 120 E Percent 5 Non-E Percent 95 Non-E Octane = ?? 97.89473684 OO = ((E% x E-OCT) + (NoneE% x NE-OCT))/100 OO * 100 = (E% x E-OCT) + (NoneE% x NE-OCT) (OO * 100) - (E% x E-OCT) = NoneE% x NE-OCT ((OO * 100) - (E% x E-OCT)) / NoneE% = NE-OCT

93 E10 ends up as 90
99 E5 ends up as 97.8
98 E5 ends up as 96.8
The actual ethanol percentage can be lower then the E number, so the above is worst case.
I have used an octane rating of 120 for the ethanol. If the ethanol octane rating is less, then the loss in octane will be less than the above figures.

Beat me to it Rob 🤣
I'd been doing rough calculations and at 113 octane for the 5% it was going to be changed by less than 1

I’d imagine it helps not irradicate completely.

Food for thought, I use E5 in my bikes and small engines (mower, blower, strimmer, hedge cutter, chain saw and chipper). I normally run the small engines dry at the end of the season and use fresh fuel at the start of the new season. I have started adding Sta-Bil Fast Fix which is probably a placebo but in theory keeps the carbs and fuel lines clean. Every couple of years I stick the carbs in an ultrasonic bath or on the rare occasion there is a blockage. The small engines are still going strong after 10+ years use. I have 2 bikes with carbs, the 4l0 and a Firestorm and I leave a full fuel tank in them over winter and run them up to temp once a month. Along with carb cleaning I have not experienced any negative ethanol issues to date. That is not to say it won't happen but I have stoppped worrying about the damaging effects of ethanol. A take away from the videos for me is not to store fuel in any machine for long periods (3 months in my mind) and to run a stack of fuel through the machines during the season. Thanks for posting the videos, enjoyed them

And just to add Esso's new synergy supreme E5 was 3% ethanol content at my nearest garage.

It's marked on the pump as E5, which means contains "upto" 5%. I removed 3% ethanol mix

That’s what I thought. Knowing that is it worth removing that small amount?

Eventually got a tap on my 4th attempt.
Taps identified as being suitable for 8mm fuel pipe with barbs are not!! Sellers always measure the OD of the barbs!!!!
