Hi guys, I found two 5 liters countainers of Shell Helix HX5 15W40 that i bought a few months ago for a car i no longer have. This is an API SN oil, which i think is mandatory for E85 and it is the only fuel i run but there's nothing like "MB 229.1, VW 505.00..." written on the container. My car's owner manual says to use MB 229.1 oil only. (1998 Mercedes W202, M111 engine). I would assume this oil exceeds the needs of the old 229.1 specification being a recent API SN oil. Is it OK for a short OCI or should i get rid of it ?
