En in Belgie is het prijsverschil tussen 95 en 98 maar 0,8 cent per liter (dus 0,008 euro).
Dus op een tank van 50 liter kost dat 40 cent meer...
Bij sommige pompen gaat dat verschil misschien wel meer zijn, maar ik heb geen problemen met enkele centen meerkost.
En hier nog een (stukje) van een artikel over de verschillen tussen de USA en Europese "super" benzine:
It should be noted that this higher rating seen in Europe is an artifact of a different underlying measuring procedure. In most countries (including all of Europe and Australia) the "headline" octane that would be shown on the pump is the RON, but in the United States, Canada and some other countries the headline number is the average of the RON and the MON, sometimes called the Anti-Knock Index (AKI), Road Octane Number (RdON), Pump Octane Number (PON), or (R+M)/2. Because of the 8 to 10 point difference noted above, this means that the octane in the United States will be about 4 to 5 points lower than the same fuel elsewhere: 87 octane fuel, the "regular" gasoline in the US and Canada, would be 91-92 in Europe. However most European pumps deliver 95 (RON) as "regular", equivalent to 90-91 US (R+M)/2, and deliver 98 (RON), 99 or 100 (RON) labeled as Super Unleaded.
