Best option for next oil change

[Henry964]

I am currently using Liqui Moly 10W-40 Mos2 Oil in my 1993 Porsche 911 with 100000 miles and happy with it, but I was thinking about using a Synthetic 5W-40 next change (Motul or other top Euro brand) and on top add to this oil the Liqui Moly Mos2 additive.
Since I live in Argentina most EEUU brands are not available here (no Brad Penn or others)

What are your opinions on this, keep the 10w-40 Mos2 or change to synthetic 5w-40 plus additive?

I always thought Liqui Moly was synthetic. Is it a blend?

use what you have been using for the last 100,000 miles it works well
no need to change unless you want to

The 10w40 with Mos2 Lubro-moly sold in the US is a blend. I am going to use it in my 95 BMW 525i on my next change.

Thanks everyone for your help!!! still my question remains unanswered, keep the Liqui Moly 10w-40 with Mos2 included in the oil or add the Mos2 additive to a newer oil 5w-40?
