Maybe I'm not thinking right, but how can running only 1engine save

that one engine, causing higher fuel consumption?

Reminds me of those vehicles that shut down half the cylinders when
cruising. I wouldn't touch one of those vehicles...it's quite hilly here
in the city and the province in general.

Lots of hills where i live. Friend got his wife a new GMC SUV. He says 28
on the highway and around town 14 mpg with the big V8 shuts down 4
cylinders when cruising. Friend with a new
Corvette says, ease up to 90 mph and cruise on the 4 cylinder mode. 46
mpg. Sounds like they are doing something correct.
