So, bottomline would be that you bought EP from american Walmart and even so received an EP containing PAO / HC more or less according to the current japanese MSDS? Therefore in spite of the July MSDS of US AFE/Vanilla you might receive the GTL version according to the September MSDS of Japan's AFE/Vanilla, ordering from US Walmart for China at least? All in all not that much different from global Shell sites' and sheets' inspirations then
Enjoy the wax as you'd enjoy the PAO.
