For vehicles introduced / designed before ethanol was added, there are problems that it can degrade fuel lines and seals in the fuel systems and give problems with fuel tanks.
For steel tanks there is a problem with water (ethanol often contains water, it can separate out, the water drops to the bottom of the tank and rusting problems occur)
For Plastic and Glass Fibre tanks the Ethanol attacks the plastics. It has led to de-lamination of glass fibre tanks and swelling of plastic tanks. I have witnessed this myself. Having initially dismissed it as a bit of hype, I have now found that it is a real issue - I can no longer raise my tank without the front brackets fouling the top yoke. Previously they cleared easily. I have now modified the fixing brackets but the brackets still rub ... and I guess the tank is still growing.
A Petition has been started but I don't think it is well publicised - let's do our bit to address that.
Please publicise this on all forums and elsewhere. Encourage all to sign the petition ... we really don't want problems with degraded fuel lines and tanks - the consequences are frightening.

BenWah ..... any chance of a mention of the problems and the Petition in your Magazine? I think this is of real interest to owners of classic machines
And for those who want to try to avoid Ethanol, I found this posted in The Kettle Club Forum last September. Obviously this is a changing situation and it may not be accurate today ... but it's better than no info:

Not sure if this helps, but I read some pointers on a classic car racing web page re ethanol content and associated damage. Not sure how accurate content is, but it seemed well researched. Anyway, I'm filling up with Total or Texaco Super since reading their findings: See below:
BP Ethanol added at 5% to unleaded petrol at all sites across the UK. BP Ultimate (super unleaded) does not have Ethanol added, except in the South West of England.
Esso Ethanol is added at 5% to unleaded petrol at most sites in the UK. Esso Super Unleaded petrol does not contain Ethanol, except in the South West of England (Devon & Cornwall)
Shell Shell has repeatedly refused to answer the question. It is therefore an assumption only, that all Shell petrol should be considered to contain 5% Ethanol.
Texaco Ethanol is added at 5% to unleaded petrol. Texaco Super Unleaded petrol does not contain Ethanol.
Total Ethanol is not added to any Total fuel (including standard unleaded petrol). Except in the North West and South East of England.
