My 10 Prius is closing in on 20,000 miles. When I filled it up a couple days ago, there was 604 miles on the trip odometer and the average mpg was 62.2 for that tank. I've seen it over 62 before but during a tank and it never made it the whole way. I do drive conservative but am in no way a hyper miler. That little bugger just does a great job saving me $.
