How many miles do you get on a full tank?

Not diesel, and it's a puny 3.0, but 5 speed manual so I endure
very high highway cruise speed RPMS.
I know this pic is repost...just fyi.

Edit...I knew I had done way better than that so I dug up the pic of our
Best Ever mpg from a trip last June: the Mtns to NJ to see the kids.
No A/C on most of the way, (it was quite cloudy & cool), never got over
80, etc. NEway, 568 on a fookin tank!
