Agreed. I always use E5, which (I'm told) often doesn't contain any ethanol as the '5' part is the maximum allowable. 15 cents per litre more expensive to create Euro 300 extra annual cost implies 2000 litres per annum, which for most of us is probably way more than we would likely use. At 5,000 miles per year, 45 mpg, that's around 110 gallons, say 550 litres, 15 cents difference would be less than Euro 100, a small cost to help protect the engine.
