The second post today, it must be Christmas. I've booked my car in for a service at Maranello. They normally use Helix 5 - 40w. I read on the long and informative variator chat that using a Mobil 10 - 60w may due to the thickness of the oil keep oil in the lifters and therefore avoid the intermittent clatter I get on startup. Do any wet sump 4.2 drivers use this oil?

I think they use it more in the US, here we all use Shell Helix Ultra 5w40 fully synth. Best to stick with what the manufactures spec.
