I have read that you can use synthetic Mobil 1 15w50 in the hydro system. With this do you need the additive still? Is there much difference between the synthetic and the standard 10w40?

You do not add the Lubrizol when using synthetic oil.
As far as the differences, there is plenty of reading here and on the internet about it, I am no expert myself.
