Thanks for the ESSO link will check it out. I know when I live in Huddersfield my local ESSO told me they were E5. I use the ESSO station at Elgin all the time  :001:

Interesting study here about water in petrol. Apparently, ethanol is hygroscopic (absorbs water) whereas petrol is hydrophobic (repels water). So, any water in E0 fuel just sinks to bottom of the tank (with potential corrosion issues) whereas E10 holds the water in solution so that it passes harmlessly through the engine.

Of course, thats only part of the problem because E10 tends to absorb water from the air so is likely to contain more water than E0 as time passes. There is also a concentration level of water in E10 where it will eventually separate out and sink to the bottom of the tank as well.

In conclusion, it seems that using E10 will be fine as long as its not left in the tank for long periods where it will continue to absorb water until it reaches the saturation level at which point it will start to separate out. Personally, I will continue to use E10 but endeavour to get a full tank of premium fuel for my last rideout before using the bike less during the winter. Any winter rideouts will also use premium fuel because they are likely to be less frequent.

yes been doing a bit of reading up on the E10 over the last 18 months. basically 10% ethanol will pull its same volume in water out of the air. So if left in the tank for a long time you could end up with 10% water in your tank which is not good at all , as that is what you will first pull though you system. But apart from that You will start to see more and more fuel tanks start to rust inside. I see it from time to time in the bikes I strip if they have been standing for some time in cool places with half tanks of fuel in them. go to youtube and put this in "Ethanol in fuel - what does E10 mean for you" it is a basic talk on the E10 for anyone that has not read up on it.

I've been around for a long time and motorcycles have had rusty gas tanks 'for ever'.
I first used ethanol laced gasoline in 1982 when riding through a corn producing state (Iowa) that lobbied hard for the issue. I needed gas and the pump said the gas contained alcohol and I thought I'd better try it and find out.
Nothing happened (or changed) and I've used ethanol gasoline in every vehicle with a gas engine since, continuously, and nothing untoward has happened.
There are a terrible lot of lies going about the world, and the worst of it is that half of them are true.

Im a bit confused about your ethanol gas situation in the UK/Europe as you say your regular is E10 and premium is E5???  I just filled up yesterday here in Northern New Hampshire with our non-ethanol gas (from Qubec) and asked the mechanic about this.  He said our non-ethanol gas really is E-zero.  Its mostly sold to people fueling snowmobiles, lawnmowers/chain saws or older outboard boat motors, although I do see a lot of other riders filling their motorcycles with it.

In the UK, petrol stations will sell two choices of petrol where possible; the norm will be E10 but anything else with up to 5% ethanol will be labelled E5 and will be sold at a premium. Confusingly, the ESSO version of this petrol will actually be E0 but they have to label it E5.

Copied below from a oldish post over on the Ducati Monster site that i look in on.  Interesting perspective and completely in line with what you would expect in today's corporate world of deliberate head-in-the-sand, box ticking policy.  Also hearing of lots of problems with bikes that are not run often, with the moisture that ethanol absorbs causing rust problems in metal tanks as well as swelling of plastic tanks.
Bioethanol fuel is a bit of an ecological disaster. It is supposed to reduce the emissions but as a fuel, it is less efficient by about 3 to 5% depending on whose figures you believe.
Most of the ecology preserving organisations ( Friends of the Earth, Greenpeace) are against it.
The easiest and cheapest method of making it is to grow corn/maize and ferment the crop. Previously this crop would have been used to feed humans or animals. The requirement for a % of ethanol in fuel pushed up prices of corn/maize and caused unsuitable land to be converted to growing it. People iin third-world countries are worse off because their staple foods and animal feed are more expensive and there has been a knock-on effect on prices for meat where those animals were fed on the crop.
The amount of corn required to make just 25 gallons of "fuel" would feed a person for a year.
This is a classic case of governments meddling in the technical aspects of a problem without considering all the possible perverse outcomes when it should be prescribing the outcome it and its citizens want.

Not available in quite a few areas. Go down to the Synergy Sopreme+ 99 paragraph.

 :084: ... and possibly, like palm oil, motivated more destructive deforestation to create more growing land for these crops. :027:
