    Here in Europe, most petrol stations sell 95 and 98 octane petrol. Where I live most stations are now switching to the E10 version of 95 and keeping the 98 as-is. So I can change to the 98, but If I remember back to the (last) days of leaded petrol, it was sold for a while alongside the unleaded stuff, then was removed completely.

    It is most likely this is going to happen to E5 petrol and probably, our cars won't last long on E10, or higher levels. The question is then what we have to do to convert so that they are compatible? I'm sure o-ring seals in the fuel system are top of the list, but what else...? Any Inj/Ign calibration required?

    I know you cannot use E10 in a 430

    Does E10 equate to 10% ethanol? If so, we in the US have been on this for a very long time. I have not seen any detriment to automobiles using this mixture, but small engines, like lawn mowers, portable generators, weed eaters etc., it will wreak havoc on the fuel system for those engines because as the fuel ages and the equipment goes a long time between uses, the ethanol eats up hoses, filters, gums up the engine etc. For this reason, I either run the equipment until there is no more fuel left or I extract the fuel after the last use before winter. The 10% ethanol mixture fuel has a short shelf life from my experience. It will go bad relatively quickly if not used. However, I haven't experienced any issues with my cars using it.

    We've had E10 in the UK for a couple of years now. I run all my older cars (and my lawnmower) on E5.

    I wouldn't put E10 in anything I cared about, unless I really had to or was going to burn it all off immediately. It'll only cause problems, for most engines, if you let it sit in there or use it long-term.

    In the UK Esso Supreme (their 99 RON stuff) still has no ethanol in it at all, in some areas of the country. So the Ferrari (and the lawnmower) gets that.

    I will continue to go with Shell VPower 100 RON, as the cars have to sit quite some time over winter here in Switzerland.

    Is there any difference between running continually (on E10) or having the car sitting around with E10 in the tank? Surely the parts in question are submerged in the fuel regardless?

    I believe there is a difference, though I haven't researched the reasons, it just comes from years of using it. I would liken it to food. Which is better, food that is fresh or food that has been sitting around for weeks/months at a time? I believe E10 is more susceptible to damaging engines because it traps air moisture more and it leaves a varnish, due to the sugar in corn, on various fuel components if left to "ferment".
