i think you are talking without any background.
firstly you say the product must not be genuine then you say Amsoil is not good,
then you say Amsoil may not be series about it. I think you have just made your perception and you're not ready to accept the facts
Please have in-depth study then give your comments here, you cannot be biassed, Its a multi-National Company which is claiming its drain interval on each and every bottle and have given in detail justification for its claims with proof even on their website, with ample amount of data to back it, i think first you should study then criticise someone, I used it and found it to be the far better product then Motul, shell and castrol. I could feel the difference in performance from the minute i pored it in my machine.
