Terrible Fuel Economy

I knew I was going through this tank faster than I thought I should. I tracked my mpg for the last three tanks...I'm currently averaging 24.8mpg. I drive 10 miles each way - all highway. I am between 60-65mph the whole way. I probably add another 10 or so miles at 40-45mph once a week.

Before the last few tanks, I was at around 30mpg. I'm not using the A/C anymore than I used to, I'm not idling the car. Nothing has changed in my driving habits. It got real hot for a few days but has stabilized.

I guess I'm just floored. I expected much better than this. Heck, with my old HHR I got 22mpg even with A/C on and city only driving.

My car is a 2013 Cruze LS. I use 87 octane - no ethanol.

It is early in the break in period but then again I was close to the EPA at almost half the mileage. Different engine than yours of course, how many miles do you drive one way and do you idle the engine waiting on someone who claims they will be outside in 5 mins but more like 20-25 mins?
