Yes, I agree. I would also add compression braking as a benefit.
And with today's wide spread ratio automatics and CVTs, many engines not only spin at very low RPM, but they also don't do any compression braking, unless in sport mode or manually prompted.
Generally referred to as "vacuum pulls." If you can find a road with lots of foot hills and slip the automatic transmission into sport mode or manual mode so it rows down through the gears on decel and engine brakes, that is the Shining City on a Hill to strive for, for nice break-in runs. Goose it up the grade, let Sport Mode engine brake it on the down hill side. Lather, rinse, repeat. Living in the flat lands, could not find such a stretch of road for the GMC and F-150, had to settle for acel/decel runs on long sparsely driven flat roads, a certain stretch of a particular county road saw a lot of our two new vehicles this spring and summer.
South Jersey is pretty flat too. I'd have to go up to centra/north Jersey or Pennsylvania to find hills.
