I've been testing fuel for Ethanol content and found that it varies widely. The sticker on the pump is not always correct, nor is the official company website.It is conflicting information Bill, the official Esso website clearly states that Esso Synergy Supreme 99+ is free from any ethanol, but they are duty bound to put an E5 sticker on the pump, and the blurb states "up to 5% ethanol" I suppose that could mean from 0-5%, daft isn't, but some areas of the country does have ethanol in this grade of fuel, Devon. Cornwall, Wales, North England and Scotland, serves them right I say, that is their punishment for living in such beautiful places.
I have also made several same day power tests and found a large repeatable variation in power levels with different products.
Switching from the highest power gasoline to the lowest gives the same effect as adding 160 pounds to the bike.
