Why don't you use 98 octane? I tried 98 octane, sitting at 110-120km/h on highway to canberra and got 7.08L/100km. Surely the 0.92L/100km difference is worth the extra money for 98 octane. Say if I drive from Sydney to canberra (300km), got 8L/100km on 95 octane and 7.08L/100km on 98 octane, the price difference would be ($27.34 - 25.04) = $2.30 if you use 98 instead of 95.Quote:
