What you will get for mileage depends on the length of your commute, whether it is interstate or in town, and your preferred driving speed. Without that info I will venture somewhere between 10 and 20.

With no od I'd be happy with low teens

Keep it under 55mph. My guess low to mid teens depending on how you drive and how your engine is running.

My commute will be 45 min a day at about 50 mph the whole way it's a lot of long side roads

Then my mileage numbers stand. Low to mid teens.

Inbetween 10-20 is a good guess, but your right foot is the boss really.

If its fairly steady driving at that rate you should do 15 or maybe alittle better.
