I honestly haven't paid attention at all since getting the car. I fill up about ever 1.5-2 weeks as this point but my daily mileage is fairly low.
I drive with every setting in Sport for the time being and will likely switch regularly between Sport/Sport+ on all settings after break-in service is complete this Friday.
I would also expect my MPGs to go down after the break-in service is done as then I definitely be looking to enjoy the full RPM range. It's been hard to behave the last 1,000 miles. I do expect my smiles per gallon will increase though.
