I'd maybe think about doing a leak down test to see where it's being consumed.
I'd guess that much being consumed might be the rings.
Does it smoke much?
Have you done a compression test?
Power loss?

but with the coolant being consumed as well as oil it might just be a Head Gasket.
Hope that helps
