IAME X30 fuel / oil mix ratio & octane rating

[NikG (Nik Goodfellow)]

Pump gas in Rotax/TaG?

You didn’t have to run that fancy Atol control fuel? Lucky you ha. Again, my main concern is that we’re only looking at the octane number… it’s important to take the composition into consideration too. It’s less of an issue in UK\Ireland where the temp swings are not bad, but in the US they ethanol content can vary a lot.

You should be fine, its a leisure engine. If you were running a KZ or any engine that you can tune the squish then I would say go high on octane if you have tuned appropriately.
