It was you that made the blanket statement about turbos, not me. I used
diesel engines to prove that your statement about a turbo *always*
cannot possibly increasing efficiency because it consumes more power
(which is true) to be false.

Of course. As I said, cruising at 90 MPH uses more fuel than cruising
at 70 MPH. That's obvious. Additionally, you are correct about the
effect of drag. But MPG-wise, his car would get better mileage at 90
than it would at 70. Hence the efficiency was best at 90 MPH, despite
the higher fuel consumption rate. The car was more efficient when
powering the turbo at 90 MPH than at the lower speeds where the turbo is
not boosting (and hence not consuming as much energy).
Now the real test would be to compare the turbo car with the

The efficiency is being measured simply in MPG, which is the only metric
that counts when it comes to the efficiency of cars on the highway.
Alex can pipe in with the specifics. But it was definitely a gasoline
engine, on a V-6 I think. Highly anecdotal, granted. It's his story,
so I guess I'll not say anything more on it.
