This may not be typical, and I don't have an explanation for it, but I switched my 200,000 + mile Honda Civic to HM oil when it first came out, and it burned it off much faster than regular 10w30, or even full synthetics.
I switched back to reg oil and all's well. Oh, it still uses some, but not like that! Just based on my experience I can't recommend it, but the engineers supposedly know better than I.
