What oil for Mazda with DPF in place of C1?

[Pidziek]

Is the Mazda engine to which the manual recommends oil ACEA C1, or JASO DL-1., I stoned oil satisfies C3, for example, Amsoil AFL 5W-40 C3?
Thus it is written on the dipstick, that is to be C1.

But it's weak and greater engine protection filters and catalytic converter?

API CJ.
But if they racommend a CI (note: not C1 but CI)
any CI or higher will do. The CI-4 is the highest designation befor the oils got "emissions treated" and contains the highest amount of good additives...

As I write instructions that will be ACEA C1.
A C1 ma wymagania jeszcze mniejszej zawartosci popiolow siarczanowych od CJ-4

CJ-4 standard is no more ashes from the C1 and I do not know or can I use CJ-4 oils for cars which is required for C1 (DPF), I thought even Amsoil DEO 5W-40.


Hm ... CI-4 is better than CJ-4 when it comes to protection and greater longevity of the engine?
