fyi.... all 507.00 (and 504.00) oils are 5w30. (btw there is no oil that only has 507.00, they all also have 504.00)
you can hence use (and mix) all 507.00 oils... does not matter who is the oil manufacturer (mobil, castrol, fuchs, even halfords own brand).
obviously not all 5w30 oils are 507.00 / 504.00.... to paraphrase it so that no questions are left: all thumbs are fingers, but not all fingers are thumbs....
