I think the real world fuel economy should be considered 21/28 not 22/33.

How many miles do you have on your X1? I get 24+ on the highway with my xDrive 28i. I typically do 75-77 mph. As your engine breaks in, the mileage will go up. Even with JB4 installed, I did better than 29mpg. If you have the factory oil in the car, that seemed to get me the best mileage by removing it at about 2400 km (2000mi) or so.
