For those who may be interested... for the first 30,000 miles, our 2010 Prius has averaged 47 mpg in mixed driving. The fuel mileage does not fluctuate very much from tank to tank... low 40's (city driving or into a headwind) to low 50's (normal highway driving under 65 mph). Fuel mileage drops to upper 40's when cruising on the interstate at 70 mph.

Our 1996 GMC Suburban Diesel averages 19 mpg in mixed driving. The fuel mileage also does not fluctuate very much from tank to tank; and with a 42 gallon tank, highway cruising range can exceed 800 miles at 20 to 21 mpg.

Good post. It may convince someone to get rid of a gas guzzler

Interesting - you have 2 vehicles at the opposite end of the mpg spectrum! Didn't really realize that a Suburban could travel so far without having to fill-up (that is an amazingly large tank; I can only imagine having to pay for said fil-up!).

Your comment regarding the mpg drop of the Prius at 70 makes me shake my head every time I see one passing me on the Interstate - what is the point of owning one if the driver isn't looking at reaping maximum mpg?

Don't be so critical. At least its not another "Do you..." post.

Any post without "do" or "you" in its title is worthy.
