I do engine brake regularly, but i don't go through all the gears until car stops. I've been driving manual all my life and it kind of happens automatically. For engine break-in I would for example go down a hill in second or third (depending on speed) with no gas, and let the engine brake the car - the rpm-s will slowly go up and the car does down the hill and slows down. On the other hand, on a level ground, or up a hill I would also accelerate from the second or third full throttle until about 4000 rpm-s and hold it for a minute, then switch into 4th and drive normally.... And so on.
My driving style is such that I often find myself around 4-5k rpms in the city. For highway, I would use 5th or 6th or even cruise if it's a long trip. Haven't done that with this Foz yet.
Definitely on a MT the rpm-s will be higher and vary more sharply. Every car I had so far had no oil consumption, or any other issues with this driving style. A well build engine with redline at 7k rpm-s or so should not have any issues at 4k rpm-s.
I drove all kind of automatics and CVT-s and I understand how they work, definitely lower engine rpm-s, maybe short peaks quickly resolved by switching to a higher variable gear (= lower rpm-s). CVT keeps the car at the lowest rpm needed to maintain the current speed. On a manual, the driver chooses the rpm of the engine - remember peak torque is usually around 4k rpm for most engines.
For example, if i want to pass on a 2way road, I would normally get closer to the the guy in front of me, switch to a lower gear (depending on the speed) that would bring the engine close to peak torque rpm, then full throttle, pass, merge back to the left lane and switch the gear back to 4th, 5th, etc, whatever the case.
On a CVT, in the same situation and assuming you don't switch to manual paddle shift, you would just floor the gas, the transmission will usually switch to a higher gear - but not always optimum torque rpms - and you can (slowly) pass. Traditional automatics, or double clutch automatics will react differently (usually better). The sport mode of CVT and automatics will usually keep the engine revved up higher so you have access to an optimized torque output.
Of course, even with MT I can drive in the city in the 5th gear an keep the rpm-s under 2k rpm, and that WILL give me better gas mileage, but the car will not be available for quick maneuvers unless you downshift. CVT-s keep the engine at that level rpm-s, that's why people say "CVT-s are better for mpg". Of course, because you move like a snail and let the engine chill.
