hmpf. Here in Norway (and Europe I suppose), 95 octane is standard. 98 octane is also available at stations but apparently only accounts for 6% of total sales. Plans to introduce 92 octane has met with resistance at gasoline distributors and AFAIK is only sold today by Jet, a distributor owned by ConocoPhillips. They started to distribute 92 instead of 98 back in 2002.

92 octane accounts for some 30% of gasoline sales in continental Europe. This has lead car-importers in Norway to accuse the oil-industry of wanting to preserve market-share for the more premium blends. The oil-industry itself maintains that the engines of Norwegian cars can't handle lower than 95 octane.

Note that in Europe the octane number on the pump is RON and not AKI (=(RON+MON)/2).
