Garlic Oil (the oil that comes from pressing garlic) is good for a lot of things including cleaning the gut after worming and medicating but a wormer it is not.
I definitely agree that it is not a dewormer! More like support for the immune system to cope with parasitism. Except for it's role as a prebiotic, I imagine most of the beneficial effects are mainly concentrated in the first part of the digestive system in a preventive role.
So, I promised a sampling of studies I looked at:
