Having just topped up my 19S at the local Esso station in North Warnborough, Hants., I noted the placard below relating to Esso Synergy Supreme + Unleaded 97octane. It has been called this for some time but what has also now appeared is an E5 label on the pump replacing the previous BS7800, shown in the second photo. This would indicate that the fuel might now contain 5% ethanol which is contrary to earlier claims that Esso Synergy Supreme was to remain ethanol free for the foreseeable future, other than in the SW.
The E5 label probably refers to what is about to happen as my own test on the sample purchased showed it still to be ethanol free.
It most probably makes it quicker to re-roll tankers from regular to supreme etc. Some fuels cannot be transported in a tanker that has had ethanol fuel in it unless it has been cleaned, I would imagine regular and supreme are compatible and no cleaning is needed between loads.
I noticed this on the Shell pumps as well the other day e5 stickers
Oh dear, that is not good. The reason for renaming Esso Synergy Supreme unleaded to Supreme + unleaded; is + ethanol, making out it is of benefit?
Those stickers appeared on the pumps at my local station weeks ago. I emailed Esso about them and they replied that they have no intention to put Ethanol in their Synergy Supreme in the areas where it was already ethanol free. Which is a relief.
I noticed my local Jet stations had new labels with E5 on all petrols including Superunleaded - I have emailed Jet petrol asking about Ethanol addition to their Superunleaded but have yet to receive a reply
