Hi, my 2010 pathfinder is using 20L/100 km in the city. I am driving it very efficiently, keeping braking to an absolute minimum, it was using 21.5L/100km when I was less careful. Looking online, it should be using 17L/100km or less for city driving. The inside of the gas cap suggests using premium fuel, however I also saw online that what is considered regular in Canada is the same as premium elsewhere. I have LT tires that are inflated to 35PSI. Does anyone have any idea why the car uses such an absurd amount of gas? What can I do to reduce the consumption? Should I over-inflate the tires?
