This is a milestone for me. I just filled up at 60.1 MPG at 601 miles. I had a flashing PIP but pushed it the last 10 miles to get the 600 mile tank. I now have 5000 miles on my Prius and am getting the hang of P&G. I have made no modifications to the car yet and have concentrated on P & G with this tank. The only thing that I have done is increase my tire pressures to 44/42 the maximum reccommeded on the sidewall. [attachmentid=8118] Thnks to all the people who have posted techniques and instructions that helped me learn the different ways to drive the prius. There is still a lot to learn. Now for the 70 MPG tank.
