Exactly the same for the first 6 or so listed and the last few the same in different orders. It has worked perfectly for me for almost 10 yrs. with the same engine. Having worked in the service depts. of Honda and VW I can attest to the Honda being about 1/3 the price of the BMW Pentosin. I do have some of the normal seepage from the heads during the change of seasons, but hardly enough to change the level and never visible on the ground-only detectable by slight odor. I usually add 2 of the small Subaru cylinder head conditioning magic to the coolant if I have to drain it completely to change a hose or tank. YMMV.
