well it isn't the Mobil 1 if you used 5w-20... i just switched last week and have been driving the same (except for a few more WOT runs than normal since it feels so buttery smooth now 
) on the exact same route at the exact same time of day as before. the week before the switch i was getting 12.2mpg, this past week, i got 16.5mpg. traffic was exactly the same, used the same fuel from the same gas station, and, if anything, my tires were even more poorly inflated. you must get to do a lot of highway driving if you're getting over 20mpg... though, it IS a V8 Mustang so i don't care too much about it, i was just shocked at a 4+mpg increase from different oil. when i would drive as efficient as possible before, the highest i ever got was 13.4mpg.
