Regards, David Joyce > 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.

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.

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!
