So it looks like your 98 is equivalent to the US 92.

Conventional 'standard' "Premium Unleaded" petrol in the United Kingdom, Europe and Australia has an octane rating of 95 RON, and in North America it is AKI/RdON/PON 91-93 (RON 96–98). However, higher octane "Super Unleaded" - often formulated with higher quality additives, is usually set at around 98 RON in mainland Europe; but this can vary by market. Most oil/petroleum companies now 'market' their own Super Unleaded petrols under a unique name - and the current name for Shell Super Unleaded fuel is "V-Power". Like most Super Unleaded petrols, V-Power also contains higher concentrations of detergents and other additives to help clean the engine and smooth its operation.
In Australia, from October 2006, Shell and
Coles Express re-branded Optimax to V-Power (98 RON). V-Power Racing, the ultra-high performance variant has a rating of 100 RON although Shell have decided to phase out V-Power Racing from 21 July to mid August 2008, instead recommending V-Power
[2]. The previously obtainable higher grade V-Power Racing which contained 5% ethanol to boost V-Power's octane rating to 100 RON has now been phased out by Shell due to a "changing market".....
In the United Kingdom and Denmark (where Super Unleaded must be a minimum of 97 RON), V-Power has a rating of 99 RON (whereas V-Powers' predecessor Shell Optimax was rated at 98 RON). There is one other 99 RON fuel available in the UK, namely
Tesco MOMENTUM99.
Seems u are correct.....
