The price of petrol I paid during June 2017 averaged $1.30 per litre for 91 Octane unleaded add 10-15 cents for 95 Octane and usually 15-25 cents for 98 Octane, location is Melbourne Australia. The last time I looked diesel was price $1.30 per litre. Petrol prices where pretty consistent throughout the month except for the last week when they dropped into the $1.25’s with a $1.19 on 30 June.
Note that fuel prices vary according to area and the level of competition and a whole heap of other factors like shopping discounts and so forth, however unreasonable high prices (relative to crude oil prices) is greed. Also note that the Octane level I post here represents Australian measurement which is different from those in other countries eg. US.
