I've checked it on a few tanks, I get about .5 mpg better on D. Hardly worth being concerned about. My daily commute is 50 miles, about 38 of it interstate @60-75mph, about 8 in a two lane 55 zone, the rest through town @30-40. I suspect the difference would be greater if the proportions were different.
