At the moment in the UK aircraft should not be flown with fuel that is containing alcohols (Methanol/Eythanol) as this can contain water increases the chance of carb ice forming.
Aviation Mogas is free of alcohol.
As said above the Rotax can use fuel that has some alcohol in it but it is not yet approved in the UK. I know of one Rotax supplier that will sell you a fuel testing kit that you can use to check for alcohol in MOGAS to tell you if it is fit to put in your aircraft.

“UK aircraft should not be flown with fuel that is containing alcohols”
This does not apply to Micros. Some of the Rotax 912 group a versions are identical from an engine / fuel system POV. The micros have been runnig fine on the stuff but the Group A versions cannot run on it legally. This should change soon. The official CAA test is also not capable of detecting small amounts of alcohol.

Ah thanks for that A&C I thought I had heard of mogas users just popping up the road to the local petrol station using jerry cans for fuel . Is this not then permitted even in "permit" (hoho) aircraft?
Edit. Thanks for extra info Rod

Most people I know go to the local filling station. The CAA test is carried out and the fuel is used. Theory is the new arrangements will come in before any of this changes, but we will see. Regs for permit and CofA aircraft, which are cleared for mogas use, are the same.

"are there then some car fuels which do not contain alcohols? or are people simply ignoring the regs?"
The regs say test the fuel, if pass, use, if not, don’t. Biopetrol is a complex subject, some oil co’s use ETBE which is ok, others do not use Alcohol in some fuels but do in others.

Tecnam's range of EASA certified aircraft are allowed to run their Rotax 912s on Mogas to the standard (road fuel) Euro spec of EN228 - up to 10% ethanol. It's stated in the Type Certifcate Data Sheet for the aircraft (and the 912) - including the P2006T twin.
I recently asked two CAA surveyors who wins the UK v EASA contradiction. Their view was that if EASA says EN228 Mogas can be used and it's stated in the TCDS then that's good enough to them.
Just because an airfield sells 'Mogas' don't be fooled into thinking it's alcohol free. When I spoke to Sywell's supplier they stated it was standard road Mogas up to 5% Ethanol.
Halfpenny Green advertise their Mogas as guaranteed 'alochol free'.
