Gents, In search of a Euro oil for my Bluetec OM651, I came across the above 3 flavors of Ravenol. Besides the price and specs (229.51/.52), can anyone help shed some light on what would be the advantage of the "Racing" formula? I haven't tried Ravenol yet, but if there's some magic elixir in the Racing version to improve longevity and performance in my Bluetec, I would surely be interested. Currently at 106,xxx miles and no issues (DPF or otherwise) to report with current oil choice (yes, I read the whole 12-pg LM overrated thread, and that's what I've been using). Thoughts please?
