UK E10 from September ?

Post

Vivergo is to recommission its ethanol-and-cattle cake-from-wheat plant (built in anticipation of UK E10 compulsion)

we are told E10 will 'be available' from September (it won't from Vivergo)

does 'be available' mean compulsion ?

more for the tax man of course

Yes, E10 will become the standard petrol from this summer.
During summer 2021, the standard (or ‘Premium’) petrol grade in the UK will become E10.

yes ..... today is the UK's E10 day .... (E5 has disappeared except as super unleaded) ....

compared to 'old-school' petrol fuelling .... our cars will have ...

0.5% more energy per cylinder-full of air - so increase their maximum power by c. 0.5% ... but ...

our fuel will have c. 3% less energy per litre .... so ....

fuel economy will fall by c. 3% ...

fuel duty will not be correspondingly normalised (reduced) as was done in the normalisation of petrol with diesel duties
so yes this another stealth tax increase

on delivery 1000 litres of E10 fuel will contain 100 litres of anhydrous (dried) ethanol we can assume
this dry ethanol will strongly absorb c. 4-5 litres of water from wherever it can
(so one might be buying 99.5% E10 fuel/0.5% water for the price of 100% E10 fuel)

low levels of absorbed water actually reduces the corrosion potential (that anhydrous ethanol has)
and hydrous ethanol production is environmentally better .. so ...
some countries use it eg hE15 - also high ethanol blends generally use hydrous
anyway water up to 5% absorbed in the ethanol might be better than was any (water unabsorbed) in 'old-school' petrol

I'm a bit worried about this.

I've got a weekend car with a tuned zetec silvertop with Weber 45 carbs and the uncertainty on the other forums I frequent is how the newer fuel will affect the carb, jets and seals.

Does anyone have any intuitions on that here?

Yeah tank the expensive e5 or e0 gasoline.

this link seems to work works in Explorer but not in Edge

what worries me for my almost shopping-only car is Phase Separation
if left by infrequent use of the car the ethanol will absorb water from the atmosphere
at some level maybe 2% this will cause PS (the alcohol/water falling to the bottom of the tank ie fuel pickup)
the car fuelling will thereafter be alternating between almost-gasoline and alcohol/water

PS seems to be a known problem ...
PS causes starting/running problems as the alcohol/water vapourisation is poor

I think alcohol doesn't absorb water after reaching the Azeotropic point (c. 95% ethanol 5% water) ?

a uni test showed that only BG Ethanol fuel system drier and ISO-HEET additives worked (contain IPA or methanol)
also anhydrous alcohol of course

btw
we are told that the mandating of E10 will save three quarters of a million tons of CO2 annually
does this take proper account of the carbon costs eg of the imported sugar-cane ethanol ?
when it becomes wheat ethanol UK-sourced by Vivergo - is that ok because millions more cattle will get feed ?

Where I live in the US we've had E10 gasoline for years. I actually live in a region that opted into reformulated fuel standards as well.

In day to day driving and vehicles,the MPG change was very small, but existed. No issues that we didn't have with regular fuels as far as performance or anything maintenance related.

The only thing I've found that hasn't liked it was two stroke engines, and the only ones I have are weed whackers, so it's not like they are high end stuff. I started using the synthetic fuel in my new one, it's expensive but I don't use much and and has great shelf life.


For quite some time we had a "spare" vehicle that was rarely driven, two different ones over the years. I had times where I didn't even crank the spare car for months at a time, and no issues at all with fuel.

FYI "premium" fuels may well remain not-E10. For example, Shell V-Power will remain E5, and Esso Synergy Supreme+ 99 must be labelled E5 but is actually "E0".
