    5w-40 or 10w-40 will be fine. 5w-40 would offer a bit more protection. 5w-30 is to thin.

    5W40 fully synth... 10W40 is semi synth in vag spec and not something I would use personally in a turbo engine

    The N75j causes a boost spike and makes the car feel a bit quicker but this usually causes the car to go into limp mode so not worth it as you said yours is already mapped anyway, the standard n75 will do all you need already on the car. The 4bar fpr is only going to be needed I think with larger injectors.

    For here (Bulgaria) time is rather large temperature range (from -15 to +37 degrees Celsius) I use 5-40w but I decided to try another oil with a wide temperature range. At the moment I put 0-50w, but I passed quite a few miles to give correct opinion.

    I use Shell Helix ultra, 5w-40, have had it in my agu for about 6k miles now and has been perfect. Have a trip over to oilman, got some bargains at the moment
