How quickly everyone forgets...I've been posting this picture on an off since 2009.
It's become darker but on the right notice it says 33.6
I've gotten better since then. And 34-36 isn't a challenge
And for the record I've noticed that the car gets its best mileage just below 2100rpm. That usually between 70 and 75.
Also. I did some quick math and I figure that the minimum drag point for the 145 is about 95 knots. That explains why I and several other members have noticed that mileag doesn't substantially drop off until above 120.
I've gotten 26mpg cruise while doing 110 in my car before.
