From Wikipedia --Eric you are correct. learn something every day
Different countries have some variation in what RON (research octane number) is standard for gasoline, or petrol. In Finland and Sweden, 95 RON is the standard for regular unleaded petrol and 98 RON is also available as a more expensive option. In the UK, ordinary regular unleaded petrol is 91 RON (not commonly available), premium unleaded petrol is always 95 RON, and super unleaded is usually 97-98 RON. However both Shell and BP produce fuel at 102 RON for cars with hi-performance engines, and the supermarket chain Tesco began in 2006 to sell super unleaded petrol rated at 99 RON. In the US, octane ratings in unleaded fuels can vary between 86-87 AKI (91-92 RON) for regular, through 89-90 AKI (94-95 RON) for mid-grade (European Premium), up to 90-94 AKI (95-99 RON) for premium (European Super).

In the Netherlands we have 95 normal, 97 (new "enviroment" feuls), and 98 ron .
Germany had in the past 91 or 93 ron, we did'nt
we did have 98 with lead adictive but it is vanishing these day's.
asked why, and to few bought it.
