By the time it is due for another oil change it will be down to the 8ml that adhere to the internals.
I used a mountain bike tube, exact size I do not know. I think the sleeves are about 1 inch long. Two photos attached.
My downtube is slightly larger diameter than the top tube, I do not recall if I used the same size sleeves or not on both tubes.
