Has anyone found any evidence that Synergy Supreme+ 99 conforms to BS EN 228, please? My inspector reckons that it doesn’t and has suggested that I will need to use UL91. As the nearest source is 60 miles away and our airfield has prohibitions on storage of any volume, being able to keep using locally sourced Mogas could be the difference between keeping flying and having to give up.
Just to clarify for those who have just joined this thread recently, the Esso website states about Synergy Supreme+ 99:
"Although our pumps have E5 labels on them, our Synergy Supreme+ 99 is actually ethanol free (except, due to technical supply reasons, in Devon, Cornwall, North Wales, North England and Scotland)."
So it's still UL91 for me in Central Scotland. However, Miscellaneous and others have demonstrated that even regular unleaded still contains no ethanol in parts of the North and North West of Scotland (presumably because it comes by boat straight from Immingham, rather than being supplied from Grangemouth).
