Also just be aware that various countries use a different octane rating for their fuel. The "octane rating" on US pumps is not the same as the RON rating used in Europe and elsewhere (including Australia). 89 octane in the US is - I understand - equivalent to about 92-93 RON. Here in Australia our petrol (gas) is generally available in 3 RON specs - 91, 95 & 98. Which is why our recommended minimum fuel RON is 95.
