I haven't checked prices recently and I can't remember what it was relative to regular petrol (Which you might say is expensive). Is the eye watering price down to duty or simply the price How much is it per litre (In making a comparison, the cost of anti ethanol additives need to be considered) At the moment I use super unleaded, as the ethanol in that is not reckoned to be a problem.

It's the raw fuel price that is high, it has a lot less duty on it than road fuel. You can use AVGAS on the road but you will have to pay road fuel duty on it which would make it scarily expensive. For example, at Wolverhampton airport it is £2.10 per litre and that is BEFORE you pay road fuel duty.

Details on duty rates can be found on the HMRC website.

The reason that veg oil is exempted from fuel duty is that it is not a fossil fuel, of course.
