David, I'm especially interested in your 914 Europa experience--but would like
to be sure that we're using "MOGAS" in the same way. I should have said "regular-grade
automobile gasoline," which in the US is 87 octane. Permium gasoline
is generally 92 or 93 octane here. Rotax specifies 91 or higher for the 914 and
912S. The 80 hp 912 can run on regular.
So if you've been able to operate your Europa's 914 with the European equivalent
of US regular--well, that's really interesting news!
Roger, there are many airfields where jet fuel is the only available aviation fuel,
and the only gasoline in the vicinity is regular grade--87 octane if you're
lucky. It's to some of those places that I want to fly. Many arctic fields
are like that and, I understand, most fields in China, Russia, and many other
countries. So you see why I asked.

Roger, We clearly have problems of translation here. I am
no expert on fuel so have taken to Google. It appears that
standard unleaded has a RON of 95 in the UK and Super
unleaded has a RON of 98, with most of Europe being very
similar. However it appears that in the States the
standard product has a RON of between 91 and 93, so
anything I said may well be nonsense in a US context!
Sorry about that. David

We need to be careful with terminology here because the term "octane rating"
means different things in different countries. In the USA octane rating is
normally quoted as the average between RON and MON =AKI. In Europe octane
rating is normally quoted in RON. Rotax use RON.
87 octane (AKI) in the USA is roughly equivalent to 91 (RON)octane in
Europe.
So, when Rotax specifies RON 95 for the 914, it is 91 (AKI)octane in the
USA.
How confusing is that!

Brian Davies
