Thanks Grant for your detailed reply. I didn't realise the 2 stroke oil used in the US tests wasn't straight mineral oil. However your advice that even mineral oil might clog later types of injectors does worry me. Do you think that the injectors on my MY2012 D5 engine might be vulnerable? Since the engine is a most valuable item, I would not do anything that might compromise it. If I cannot know whether 2 stroke oil would cause damage, I would have to take your advice and steer away from it.
