Liquid Platinum how much of your city driving is stop and go? I am in stop and go traffic a lot and do 75 to 80% city driving. The best I have got so far is 16.5 and not thrilled. Any suggestion on what I am doing wrong? Do you drive in ECO mode? I am mostly driving in standard mode.I now have 5,000 miles on my JX. I have the AWD model. I have been averaging 21.5 city and 24-25.6 on the highway. I have used only Shell V-Power (93 octane) since day 1. While these are not staggering numbers I am happy.
