Never had a consumption issue... Loss was low enough that it was a matter of maybe a cup or two over the oil change interval. A cross-country trip yielded no change on the dipstick.

My issue was that I was getting a mess all over the lower part of the turbo u-tube and it was all over the wastegate.

It is far cleaner now, though it still looks like there is an oily coating that has some pooling in the u-tube...
