Test results!
(preliminary)
I was pleasantly surprised to see that after 400 km / 250 miles of driving with minimal engine braking, there seems to be no change in the level of oil on the dipstick.
Oil consumption vs. brake pad consumption trade-off?
Of course, that's not much distance to be super-confident of the result. But I'm about to put the car away for the winter, so the continuation of the test will have to wait until next year!
