That's interesting Mr 83 man & The Juke. I was advised many years ago to use only Bluecol anti freeze in my Mk1. Now Bluecol doesn't seem to be so readily available so I asked my regular oil & fluid man who happened to have a stall at the Brooklands Double 12 & he recommended & sold me some anti freeze by a company called Morris. I just looked inside the bottle & it's BLUE. Whoopee.
Re ethanol in petrol, Esso advise me that their super unleaded doesn't contain ethanol except in the South West. BP & Texaco say the same.
