Catalysis of the reaction: 2-hexaprenyl-6-methoxy-1,4-benzoquinone + S-adenosyl-L-methionine = 2-hexaprenyl-3-methyl-6-methoxy-1,4-benzoquinone + S-adenosyl-L-homocysteine. Catalysis of the reaction: 2-polyprenyl-6-methoxy-1,4-benzoquinone + S-adenosyl-L-methionine = 2-polyprenyl-3-methyl-6-methoxy-1,4-benzoquinone + S-adenosyl-L-homocysteine. Catalysis of the transfer of a methyl group from S-adenosylmethionine during the synthesis of quinone cofactors such as ubiquinone (coenzyme Q), menaquinone (vitamin K2), plastoquinone and phylloquinone (vitamin K1).
