MPG suddenly dropped on a trip. Toyota checked car computer and found no problems
Local dealer says he can not fix it without help from SE Toyota
SE Toyota refuses to help
Problem has lasted for 3 months and have made 4 trips to the dealer
Car, bought new now has 20,000 miles, has had only one driver and has used many different gasoline brands Before this problem, car always got 50+mpg

Were you traveling at higher speeds than you normally do? With a Prius, the best MPG is often city driving.

The best mpg in my prius is creeping along in a 15 minute traffic jam. The dash pegs at 100 mpg. 46 isn't that bad. Short trips and cool weather take a toll. I leave my trip meter alone and after 2-3000 miles I average 51. I've been in the 40's when I was always checking but no more. 27k total miles and probably in the high 40's overall.

Factors affecting fuel economy:
cold temperatures, new tire tread, low tire pressure, vertical, hard acceleration and braking, speed.
 
When I first got my Prius, I was patient and slow on all of my trips, had original small factory tires, and drove in summer with fuel economy 50 MPG. After the first winter, the cold temperatures gave me an average of 48 MPG. Purchase of heavy, all-season tires cut fuel economy five percent. Over-inflating tires is a trick used to increase fuel economy, operating in the light of day leads to warmer temperatures, and getting the luggage and excess junk out of the vehicle potentially offers higher fuel economy. Kick your spouse out of the car for higher fuel efficiency.

I have two friends and I'm always bugging them about MPG, and over the course of a few years, they both seem to average right around 46-48 mpg.
