Actually I'm an advocate against a small vocal minority promoting a change of oil type away from the OEM recommendation with absolutely no long term data that shows any advantage....and I'm especially against glossing over UOAs that show a rise in iron - if you can't drive hard with Mobil 1 0W40 on board without a rise in iron then that IS a reason to be concerned.
The topic is rapidly become like the tight bearing clearance fiasco - where the idea (M1 0W40 is better) becomes fact solely by constant repetition.
