Ethanol test for pump petrol

[Mr Gazza]

Let's not forget that the octane rating is essentially different between regular and premium by very definition, and have different properties designed in regardless of Ethanol content.
The aircraft icing chart will be based on using Avgas which is 100 octane (possibly 110 octane?)

I remember trying some 5 star in my Honda 50 once.. It sapped the power and got hot.
My Dad kindly explained the meaning of octane ratings and I ran it on 2 star happily ever after.

I always try to put premium or super in my 900 injection and enjoy lots of smooth power and economy (68mpg at a 90mph cruise on a very long private runway).
If I'm forced to use regular I only notice it being slightly less good, but there is a difference.

I did suffer what I assumed to be Carb icing on my carburettor equipped 900 Monster, but the oil fed warmers were enough to fix it once they were turned on. A damp but mild Autumn day was enough to bring it on.... All to do with relative humidity. (see above)

There's another problem caused by too much ethanol!

Here's a thought; the reason we're stuck with this ethanol is a European Parliament Directive 2009/28/EC, which requires each member state to be using 10% biofuel by 2020.

Hmm...member states...2020...

Brexit anyone? Aren't we supposed to be out of the EU by 2020?

I mentioned earlier that there is currently a legal requirement for fuel companies to provide 'protection grade' petrol. This requirement runs out on 31 December 2016 and I can't find any details anywhere of what's going to happen after that. I wonder if the delay is as a result of Brexit? If I do find anything out, I'll post it here.

Not so it is for micro & light aircraft running pump fuel

Ah! Yes you're right, the little un's do run on pump petrol.

I remember many years ago when I was visiting a cousin. We watched a micro-light descend in silence out of sight behind his back hedge.
Thinking it had crashed we raced round to see what had happened, only to meet an Orange suited aviator carrying a ready can and a bottle of two-stroke.... He had run out of petrol.
Needless to say we found him enough petrol out of various car tanks to get a measured gallon. He added his oil, filled his Micro-light up and off he went, returning our waves as he climbed out... What fun.
