Hello, I came across this chat in the forums which someone recommends CJ-4 for a PD, my engine is a 2008 non DPF 2.0 PD mk5 golf, BKD I think, the only CJ-4 oil I can get is 15w40 and its mineral (non synthetic), posted a link to the oil below. I am using 507 spec now but concerned about people claiming it can damage the cams. Should I continue with 507 or switch to CJ-4?
