My understanding is that E5 petrol with 5% bioethanol blend and E10 is 10% blend. The UK have E10 as standard but that's only rated 95 octane.
2023 Where's the best quality petrol

It'll be a lower quality base fuel (petrol) mixed with 10% ethanol to bring it to 95, rather than our current fuel having a 10% mix that might give us a half decent RON. Unless the car is being used regularly, it'll absorb water and sit at the bottom of the tank, as ethanol is hygroscopic and will bond to water before it bonds with petrol.

To make 10% blend, you need to remove 10 parts of Natural and add 10 parts of ethanol - If Ethanol has lower flash point, isnt this actually increasing the final RON number? Or is it done differently?
Edit: Some further research indicates, that adding 10% of Ethanol into 95RON Natural makes it 97 RON - The question here is tho, the E10 we are getting might be mix of 93RON Natural with 10% of Ethanol, effectively making it 95RON again - and since this is the worst case scenario, I believe that being the case actually.

Question is this will we have a choice to buy 95 or straight to e10 in uk performance and classic cars have no issue as they have the option for super unleaded.
Will cars need a map for it for to keep em safe?.. this e10 stuff eats through fuel lines and rubber seals too so more things to keep a eye on there and is less range from a tank requiring filling up more often (Great thinking Ryan u Bellend

From gov.ie website:
"Move to E10 (Ethanol) in Petrol (from the current E5) will be better for our environment"
How much better will it be for the environment and at what cost?
How many petrol cars are on our roads compared to diesel? Maybe less than a third are petrol?
This whole thing is preposterous...
Is it 100% confirmed that only E10 will be available at petrol stations? Or do the public have any say about any of this?

All the info is in there to be fair. I don't think it's entirely accurate claiming it brings our petrol in line with what's available in NI and UK though.
Itll replace whats their already, E10 or nothing ...
Sure the whole goal is to eventually get rid of petrol/diesel cars, they aren't even considering if its going to be detrimental to 20 year old cars , hell itll work in their favor as an average joe soap will eventually get fed up trying to make their older car run on e10 mix and eventually upgrade to a newer car.
Its only us , classic car enthusiast that will be trying to retrofit our cars to run e10 mix safely.
Honestly, id say we have less than 10years left of enjoying our gas guzzling cars before well be forced off the roads
And the way things are going, we wont even have a choice of going to the track as they are even struggling year after year to stay open.

E5 is reckoned to be the equivalent of 97+ octane, E10 is actually less efficient and the equivalent of 95 octane...

I was talking with a buddy who works in petrol production in cork. He says current e5 is 4.9% ethonal mix. Current government requirements only require e10 to be minimum 5.6%.
They will be producing it with the minimum threshold as to keep costs down as ethonal is expensive and there is no change to the base petrol mix
This gov requirement is likely to increase the minimum ethonal content in a phased basis over the next few years in small increments, but for the moment change is minimal. The maths is only 350ml increase in a 50L tank.
