Is C3 oil okay for the 3.3TT?

[GhostGrey]

I purchased 2 cases of Motul X-Clean EFE which is a C3 rated, Mid-saps oil, not realizing the OEM recommends a A5/B5 rated oil for the GT; which is full saps. I'm located in southern Ontario. Is it still okay to use this oil or should I only use A5/B5 or better (A3/B4)?

Motul X-Clean EFE is API SN ACEA C2/C3, which exceeds KIA’s standard and is a good oil to use in the Lambda II PE 3.3L T-GDI which specifies API SM/ILSAC GF-4 or above.
