95 Octane & Fuel Economy
My Ford service provider (Dubai-UAE) said that there is an additive in the 95 octane (recently added) that's affecting the fuel economy. This answered why I was getting between 7.8 - 8.3 km/L (18.3 - 19.5 mpg) combined, which means around 500-550km on a tank (depending on how heavy my foot is). So the service provider advised I change to 98 octane - which I did this morning which gave me at the end of today 8.9 km/L (20.9 mpg) combined. Which means technically I should get 600-647km to the tank (depending on how heavy my foot is). What fuel do you use and what's your economy rate?
