ethanol in fuel

Is there anywhere that doesn't have 5%??? I want my fuel economy back and I want something that won't ruin my mini.
Even super has 5% in. Most regular can be 10%.
It's costing me more due to more fill ups and I don't want to have to pull the carburettor apart every year.
EU fuel is practically mandated to contain ethanol because of this directive: http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?...Even super has 5% in. Most regular can be 10%.

Get used to it because they are going to be adding more ethanol to petrol, not less.

For cars without a cat Tetraboost now has an anti-ethanol additive. www.tetraboost.com
Looks expensive but you only use 10ml per litre of fuel so not too bad if you don't do too many miles.

Why does ethanol ruin economy? Ethanol is an octane booster, and the whole formulation of the fuel has changed from 10, 15 years ago. Putting an 'anti-ethanol' additive in your fuel seems a daft thing to do to me.
It's a problem in older cars as it eats metal and plastic components in the fuel system. By older cars I mean 70's and older. I can't see why it would have much if any effect on economy.IIRC Higher octane and ethanol in older engines starts messing with tuning
(advancing and retarding the ignition?)
Our 1960 Land Rover is designed to run on 2* (after you've removed the bits of straw and twigs) in such a low 'tune' state I haven't noticed any difference in MPG or performance but the carb has started weeping around the joints
ETA Ethanol... does it affect engine 'lead memory' and am I going to have to fit hardened valve seats?

It ruins plastics. Weun on super currently so tesco points are building up too.
In the jazz we have in France the car gets 10% lower economy on e10 (10% ethanol).
Its a less dense fuel so need more of it for the same energy.
It actually reduces Ron numbers but can help with knock prevention.
It's the fact that it costs the same to sell but not getting the same product is winding me up. As well as possible damage yp my cars.

Ethanol has a lower energy density than petrol so by adding ethanol to petrol you lower the overall energy content.Mr2Mike said:

EU rules suck. So many cars will never work at their optimum because of this. Rubbish.
Would be nice to know if there's any benefit in the additives but their gain will only help my classic rather than economy.
They'd tell you the ethanol cuts down on net CO2 emissions because it's bio-ethanol.Would be nice to know if there's any benefit in the additives but their gain will only help my classic rather than economy.
