As I posted in the earlier E10 thread, I found that Texaco Super Unleaded in Devon has for the time being, no ethanol: at least at the Bovey Tracy filling station. Looks like all owners of early cars will/might have problems with various seals and all owners will have to consider winter layup procedures: chain saws, lawnmowers also run foul of the water content issue when ethanol lies in the fuel. It'd easy to test your local filling stations with a spare can you fill up when you are there: instructions abound on uTube.
Ethanol is here to stay so.. we just have to deal with it: I suspect it will be back to normal 15 years from now when the EU politicians wake up to the fact that land should be used to grow food, not fuel.
