While I in no way suggested for anyone to change oil from what they get from the dealer at a fair price or feel comfortable with. Australian owners pay at least $25 a litre for 507.00 from our dealers. Or you can get 507.00 spec oil for $60 for 5L from a long term reputable Australian manufacturer . Can some one put context to the below questions from a Liquid Moly spec sheet attached.
