You're often more direct about not arguing with the manufacturer's engine department when someone asks questions about engine oils, in particular about Castrol's mid-90's vintage RS 10w-60, now marketed as TWS and Edge.
In other news, Mobil has removed the 0w-40 recommendation on the Mobil1.com website for the new S65 engine. It was up for a while, but it's gone now. Now the site just says they don't have an oil that complies with the manufacturer's recommendations, or words to that effect.
