The ethanol content should be on the pump

From what I've read, the esso supreme+ 99 contains no ethanol, in most areas except teesside, Scotland and somewhere else I can't recall. Also Devon, Cornwall and NW England , all due to “technical supply reasons”

Be careful assuming that the higher RON grade doesn't have ethanol in it, it's not widely publicised but petrol companies are actually fined around 30p per litre if they OMIT to put in at least 5% ethanol With the profit margins so tight on fuel, I very much doubt the fuel companies would ignore blending some Biofuel (like ethanol) and loose 30p / ltr

From Esso website: The majority of unleaded 95 Octane petrol sold in the UK contains up to 5% ethanol as required under the Government’s Renewable Transport Fuels Obligation (RTFO).
There is currently no requirement for renewable fuel (such as ethanol) to be present in super unleaded (97 and 99 grade petrol).
Esso super unleaded petrol (Synergy Supreme+ Unleaded 97 and Synergy Supreme+ 99 ) is ethanol free (except in Devon, Cornwall, the Teesside area, Scotland and NW England). We would therefore advise anyone who has concerns about the presence of ethanol in petrol to use Synergy Supreme+ – providing they do not fill up in Devon or Cornwall, the Teesside area, Scotland or NW England. The European standard BS EN228 covers the requirements for 0-5% ethanol unleaded petrol, the labelling requirement for zero % ethanol is E5 (as is up to 5%), a E0 label doesn’t exist. We understand that this is confusing if you are looking for zero % ethanol fuel, but as advised we can confirm that our Supreme Unleaded fuel supplied in areas except those listed (Devon, Cornwall, Teeside, Scotland and NW England) is ethanol free.

Good news. My series 1 Roadster ran with oil pressure when warm around 1 bar, The water temp normally in the range 80-90 c Haven't really been monitoring the oil pressure but was a bit puzzled when I checked today. Startup was about 4.5 bar, dropping once warm to 2 bar. I had a main dealer oil change last week. Have I blown something, or is this within spec ? (can't find anything helpful in the Manual, and there are numerous threads on TM but I'm missing that specific info). Thanks for any thoughts.

That pressure range is the same as mine. When hot it runs around 2 bar, and it's always been like that.
Less at tickover.

Thanks, that makes me feel so much better ! Mind you, I don't understand the mechanics of how/why that should be.

The oil pump turns at engine speed so it runs slower at tickover hence less pressure .... oil is thinner when hot so flows easier hence less pressure when warmed up.

I'm writing from Italy so my usual temperatures may be hotter than the continental Europe or British ones but in my Roadster V6 S2 the oil pressure ranges between 2-1.5 bars (when it's moving) to 1-0.8 bars when it's stationary.
When i bought it (used, January 2020, damn you Covid) it was ranging from 2.5 to 1.5 bars, but I cannot think of a moment when anything changed and caused this drop in oil pressure. I've noticed the change in pressures this year, starting January 2021.
Everything is running fine, my water temperature ranges between 90 and 110°C, with the fan blowing at speed 1 from ~105°C, but i've also got a manual fan switch on the dash that allows me to turn it on independently at speed 2, (max speed)
