Yes I do
Not only does the oil circulkate more, it will also be at a higher temp, which will tend to break it down more quickly.
I've been running BMW motoercycles for many years, and fitting a bigger oilsump which hold more oil, does three things. One - it mean I can go longer before oilchanges, and two I can run whith more stable oil temps in the engine. Thirdly theres less wear on the engine due to improved lubrication and cooling.
It's a well known fact for these engines, and I dont see why it should be any different for cars.
If you have less oil to do the same job, you will wear it out quicker. Everytimes it circulates it wears a little, and less oil also means e somewhat reduced cooling effect, as the oil stays a shorter time in the sump and has less time to cool down.
This is also why some vicihles are equipped with an oilcooler.
