In The Netherlands, 52 stations are operating under the proprietary OK brand. 37 of them are staffed and feature a modern shop, while the other 16 are unmanned. OK has a long history in the Netherlands. The 1950s saw the brand, which was originally Swedish, introduced to the Dutch market, and since 2004 it has been owned by the Catom group. Since 2006 Catom has been working on putting the OK brand of petrol stations back on the map, with the number of petrol stations growing each year.
Also, OK is the brand name of fuels and lubricants being distributed by OK Oliecentrale, which has its focus on the business-to-business market.
