Hi, I noticed from fuel records that the price difference between 91 and 95 octane over the last couple of years has widened from 8 cents to 13 cents. Is there an explanation as to why this has occurred?

The normal price difference between 91 and 95 is 9c, but this can be bigger if the retailer is discounting the price of 91 but not premium petrol. This has become more common and retailers get away with not discounting premium because they don't display the price on the roadside board. This is why the AA has lobbied govt. to make it mandatory to display all prices which would encourage more price competition on premium petrol. The Commerce Commission also agrees with us.
