I had loud lifter noise with the 5W40 full synthetic during warm-up, I use 5W30 now with no such noise. Unfortunately 5W30 in Germany means low saps oil, on the other hand, carbon particles in the oil is reduced with it.
Yes, SynPower 5w-30 was that oil what I meant but I couldn't remember. Seems to be very good choise for 3V according to specifications of this oil.
Just make sure that you order simply SynPower, not Synpower FE which is ACEA A5/B5 + A1/B1.
