Also fuel stations with unknown price (but fuel type is known, only price is not up to date) or unknown fuel type information will be included in the result set: In the response stations with fuel prices are in the beginning followed with stations without information about fuel types and prices. This gives client at least information about all available fuel stations within requested area so client can select also station without price information, but its closest to current client position. This parameter works together with fuelType parameter. If fuelType parameter is not set, all stations within search area are in the response - with and without fuel prices.
