Ever wondered how much Ethanol is in your fuel?
Discussion
This guy has run a bunch of tests on the Ethanol content of fuels.
https://youtu.be/wgJ0VRctlz8 - see some of his older videos, also has an octane tester, but that only works with pure petrol.
A couple of points:-
1. Ethanol has a lower calorific value, than pure petrol
2. Lawnmowers and older cars can't use it as it will damage their carb/fuel systems etc. - (I use Aspen fuel for my lawnmower)
Most, but not all Super unleaded fuels have zero Ethanol, however, Esso (Synergy 99+) was the only one to state it had none, but this will change from next month, the guarantee of zero Ethanol.
All pumps must be labeled E5 or E10, however, that does not reflect the actual Ethanol content.
Typically switching to super unleaded(99), most will see an improvement in MPG and power(advancing ignition until knock), let alone the other benefits of these fuels.
Just my thoughts

I’ve run super in my cars for a while as the increased fuel economy makes it worthwhile to, most of the time. In my older car, even though it has knock sensing, I run super as it often sits for some time. It is E10 compatible though.
For the mower, and two stroke garden stuff I just use whatever, and empty them out before storing for winter. I can’t be arsed paying more for super for them, and will move to electric garden tools when mine are worn out.

I think I would avoid ethanol fuel in your mower, even if you drain it out for winter ....

The whole point of the E5/E10 rating is that it's the maximum ethanol content the fuel is allowed to contain and I'd damned well hope it's accurate! Ethanol content seems to have no noticeable effect on either of ours cars. The VAG TFSI lump on our Skoda certainly benefits from a higher knock rating, enough that it's cheaper to run it on 97RON than 95, but the difference between 5% and 0% doesn't seem to be significant. The Lotus runs identically on any type of petrol I've ever put in it.

My understanding is, that ALL super-fuel has ethanol in it, with the exception of ESSO. Who will have by the end of Sept.

Yep, and we still need more apparently, despite it being a non-issue for 99.9% of engines. Even most mowers have had ethanol-compatible components for decades.
Mowers ... Oh, news to me .... But then my Honda mower is still going strong since 2001

The fuel line in my petrol strimmer fell apart when I forgot to drain the petrol/oil mixture out over winter. Ethanol I daresay.
Probably, and cheap/old line. Stick some fresh on and away you'll be.Krikkit said:

This is a bit of a nightmare for us here in Rep of Ireland, as our government taxed Super Unleaded out of existence many years ago, and has now deemed all petrol to be E10 going forwards. Interestingly the government signage at some petrol stations claims there are no ill effects, although online they point to the UK’s published list of non-compliant cars
As I’m potentially purchasing a non-E10 compliant car next year which will need to ideally run on a minimum of 97 octane fuel, I need to find a joint solution. I’ve yet to confirm if an ethanol protector supplement can be run with an octane booster, and there doesn’t seem to be a fuel additive that does both
