My experience with over 200,000 miles on 2 different 124's, a '90 and a '92 is more like 22 to 24. Of course these miles were generally at 70 to 80 mph.

I keep very meticulous records on both my '90 and '91 300Es.
I took the '91 on a trip just last weekend. It was about half interstate and half not. The air was on about half the time. The speed was 75 on the interstate and 65 on the highways. Total trip was about 560 miles. Probably 25 miles was stop-and-go at the destination. I bought fuel at the destination and again when I got home. The fuel mileage on both legs was just under 28 MPG. It was almost exactly the same on both legs of the trip. If I was at home, rather than at work, I would give you the precise number. It was something like 27.8.
The fuel was 50% regular and 50% premium. Amoco on the first leg, Chevron on the second.
I appreciate your skepticism but both my cars do this routinely...the '90 actually generally does a bit better than the '91.
BTW, the hiway mileage you quoted is what I typically get in town.
