That's excellent considering the hills. Your average speed was 61. In the flat delta here in Tennessee, I get 32 to 34 mpg at 60 mph on good summer diesel. The EVIC tripmeter mpg, which uses a 300 mile rolling average, is fairly accurate to hand calculations if the driving style is the same for the entire tank (700 miles). It won't agree if half the tank was spent in the city before a trip.
I have seen 38.5 mpg on the EVIC at a very steady 55 mph for 300 miles nonstop when I was attempting to hyper-mile on extremely flat ground. Of course it is important to reset the tripmeter so the average starts over.
