Which oil you using nowadays in a 1.4L(55kw) petrol

Giving the thread a bump with a little help needed to clarify:
I've been using Mannol's 5w30 and have been pretty happy with it, but:
- I do have the notorious piston slap noise in my AUA
- I am in Italy, and every year it gets hotter and hotter, with 35-40C being a quite common ambient temperature during summer months.
- I do like to drive 'enthusiastically' pretty often ;)
- I don't really do long service intervals despite using a longlife oil and change the oil every +-10k km / once a year.

So, I've considered that 5w40 may be a more reasonable choice.

However, 5w40 are not 504/507 compatible, if I understand correctly?
Does it make sense to get a VW 505.00 5w40 (like Fuchs Titan Supersyn 5W40), or I should stay with 5w30 and stop bothering?

Bit off theme, but would it be worth fitting a lower temperature thermostat, to lower the engine temp a little?

I use a 50200 classed 5W-40 oil for my 1.4 petrols and change every 15000 km rather than the long life schedule. Works fine. (it is Total Quartz 9000 Energy btw)

As Joga wrote above me - 5W-40 VW502.00 will do in Itally way better than 30...
 
With oils I think as long as they’re approved and you change at a sensible mileage (ie. Max 8000 miles or before the additives have been exhausted - about which you can make assumptions or even better, get your oil analysed for a recommended change interval from a specialist), then you can’t go wrong.

I would suggest you follow the advice of @Joga and @BigBang and report back on whether the piston slap has lessened?

Is it OEM? Mine is an 8Z6 "hot country" spec, though idk the exact differences between hot and cold A2s, wondering if I already have it installed.

@Joga @BigBang @dj_efk thanks for the input! Convinced to give it a try.
I have a belt change planned in February, I guess I'll do the oil and filters at the same time.
 
With AUA and BBY it's always recommended NOT to use the longlive Oil, switch from ll to normal service intervall with vcds and use the recommended Oil (see manual) for not long life. This has way lower oil consumption, is much cheaper anf has absoltly no disadvanteges.
