E10 fuel safe??
Will my MY00 (year 2000) s2000 have any problems with the new E10 - 95 fuel? Due to new laws in Europe the regular Lead free 95 octane gasoline will be replaced by E10 95 fuel. Meaning it has 10% ethanol mixed in.
Alternatively are the 98 octange fuels, because they will have a maximum of 5% Ethanol in the near future in Europe (E5). So I could change to that fuel but its much more expensive, so I want to know if E10 is okay?
I couldn't find any info for the ap1.
Who knows or has checked it before?

Why does nobody read their owners manual? 
I've no idea what the EUDM spec manual states but will bet the information is in there under Fuel Recommendations.
Here's what my owners manual states. Yours will be similar although the octane number will vary depending on the test used. North American pump octane is an average RON and MON octanes which means the same fuel will appear to be lower octane than the RON octane rating used in EU. I'm tuned and run Shell 93 (pump octane) which, while there is no direct conversion formula, is about what 98 octane is in Europe.

Your vehicle is designed to operate
on premium unleaded gasoline with a
pump octane of 91 or higher. Use of
a lower octane gasoline can cause
occasional metallic knocking noises
in the engine and will result in
decreased engine performance. Use
of a gasoline with a pump octane less
than 87 can lead to engine damage.

Some gasoline today is blended with
oxygenates such as ethanol or
MTBE. Your vehicle is designed to
operate on oxygenated gasoline
containing up to 10% ethanol by
volume and up to 15%MTBE by
volume. Do not use gasoline
containing methanol.

Thanks guys for your replies. Im happy its fine for the ap1 my00.
@flanders I have tested both 95 and 98 and couldnt notice any power difference. Also I got the same MPG or kilometers out of the same tank (which are both very few kms lol). No noticeable difference. Which confirms they deliver the same power. I know my tank lid says 98 but common recommendation here is that 95 is fine. My tests confirmed that paying more doesnt give any benefits.

It would be nice if the S2000 would have a 'Knock Detected' warning light in the dash, so you can see if using lower octane fuel causes knock under certain circumstances.
But we don't so you can't so you IMO you shouldn't.

The ECU will detect and handle knock within a range. For those who missed this (US pump octane numbers)
