If it were me, I would use oil weight to increase cold-start performance. Use a 0W-30 LL-01 oil in the winter and a 5W-40 LL-01 in the summer. LL-01 pretty much guarantees you are using a quality, well-performing oil. Castrol seems to have a good 0W-30, and Pennzoil Euro seems to have a good 5W-40, both in LL-01.
You'll find almost no difference in viscosity between LL01 oils, regardless of what arbitrary number is printed on the front of the bottle.
LM MoS2 is a fine additive that is TÜV approved, meaning it has shown evidence to the German government that it does what it says on the bottle.
LM Motor Oil Saver is TÜV and FAA approved, and it does work.
Having said that, I don't think you need anything more than a proper LL01 oil, a high-quality filter, and 10k/1yr intervals.
I had idea about those certifications, and I'd never heard of the Oil Saver. Thanks for the info! Do you know how the oil saver is supposed to work to stop oil consumption? (I'm proud to say that I have no leaks whatsoever, even though the consumption is an issue.)
