On the way back from Moab I had one stop that yielded something like 370 miles from my last fill up and 1qt of oil . Usually between tanks if it shows oil burn it is like 1/8 to 1/4 of a quart . 1/2 quart between tanks is less common but does happen . And 370 miles out of a tank only happens out west. I normally get about 260 to 270 with 2or3 gallons left in the tank when I fill-up.
