"Can travel 375 miles on a trip to Ky and have to put quart to quart 1/2 in that time. Drive the car for several miles short distance over a weekend period and drive home another 375 miles. The return trip home, most of the time does not use very much if any. Isn't this strange?"
My comment is in regard to your opening question as stated above.
During this recent trip were you driving the car harder on the way out ? I have found(and others here have reported the same) that when city driving the 103 consumes less oil than during Highway driving. Furthermore along those lines - The faster you go, the more oil you will burn.
