I had never actually checked the MPG on the 190e 2.6L. I did a 300 mile round trip last weekend to the Equi-Fest. I was curious on what the M103 would get in it. I was running premium fuel as always, and I logged a 25 MPG for the trip. Is this in the realm of what they were supposed to get? I had never checked it before or the 2.3L I use to own previously. I, also, didn't know if they were rated somewhat better with the 300e's, in that era, or not?
