e10 fuel from e5 petrol,

[Mexican cuties]

as we have a boat 2005, and 2 cars 2005 & 2009 that run on E5 petrol any one have any idea of additives or what the bigger effect will be, understand that pre a certain year E10 wont be compatible

thankyou

For the cars, E10 should be ok, but I’d just use a super unleaded, preferably Esso Supreme+. The Esso pumps show E5 labels on the pumps, as law requires, but that fuel is zero % bioethanol.

thank you

You're likely to find that Esso Supreme+ is the most expensive fuel out there, I paid 151p per litre for some a couple of weeks ago. Your wallet will suffer less if you fill up with E5 rated Tesco Momentum 99, currently 139.9 near me.

thanks, just wondering how many pumps will still have it, and how hard it will be to get, one of the cars is american and the other a crossfire. will have a closer look next time when filling up

Are US cars not usually rated to run on pretty ropey fuel, even 87 Octane used to be sold over there as one of the options if I remember correctly?

There is no standard compatibility year, it is unique to each manufacturer and model. Some cars more than 30years old are compatible. You can check here https://check-vehicle-compatibility-e10-petrol.ser... or with the manufacturer.

Super Unleaded is still E5.

How can it be "as the law requires it" when the law requires 5% or 10% ethanol (E5/E10), if they are not putting the ethanol in? Sounds like pub talk, rather than fact.

[pherlopolus]

The 5% thing is the maximum allowed amount, not the actual amount

"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)."

Octane shown in the UK is measured by the RON method, whereas in the US it is AKI. There are 4 to 6 octane numbers difference between the two measurements:

‘Because of the 8 to 12 octane number difference between RON and MON noted above, the AKI shown in Canada and the United States is 4 to 6 octane numbers lower than elsewhere in the world for the same fuel.’

Ah that is interesting! I could have saved some cash when filling up had I known that!

Ah, didn't know that.

They must be buying offset credits then to make up the short-fall. Possibly why the fuel is more expensive.
