what mileage do you have on your Rio ?
I have given up driving to economy for the time being until the car passes 20,000 miles.
Then I will see what the economy is like then.
I get an average of 50mpg over a tank full.
Oddly enough, if I drive at 60mph on the motorway for long periods, I am sure I get less economy as the engine's turbo is not fully boosting.
