Maybe you already found these documents, there's a lot explained, but not all is clear to me. This is a quote:

C3
Stable, stay-in-grade oil intended for use as catalyst compatible oil in vehicles with DPF and TWC in high performance car and light van diesel and gasoline engines. These oils will increase the DPF and TWC life. Warning: these oils may be unsuitable for use in some engines. Consult owner manual or handbook if in doubt.
This is where I found the quote:
