basically for 0W20, no problem for all the honda current model
since 0W20 for 2400cc and below NA only all is suitable
but proton might need some labrat to do this. haha
due to engine piston tolerances played a huge problem here

so call in Honda USA, been using this 0W20 for 5 years, well before 0W20 is 5W20, which are also consider as lower visco oil

other means added with molyb additives certainly is not using G4 base oil.
