AXO 5

It would appear super unleaded doesn't exist in Ireland.
I'm reading some fuel is high octane but unsure.
Advice please?

Maxol E5 99RON

Go to the suppliers web sites they should have the specs published there. As unleaded varies in RON value in the ROI.
Carry a bottle of Millers octane boost for when you are desperate.

Irish TuneR

The south doesn't have any im afraid, you don't need specifically E5 as all petrol here has that ethanol content now, more or less. As above, carry an octane booster if you want although the car will adjust itself for the crappier fuel.

Maxol fuel isn't high octane.
I used topaz fuel all week and did around 800 miles on it and it didn't miss a beat!
