Liqui Moly Oil Saver (fka Lubro Moly Oil Saver) shouldn't change the grade at all. From the manufacturer's website, it says:
Regenerates rubber and plastic engine seals such as shaft seals and valve stem
seals and prevents oil stains under the vehicle. Counteracts oil dilution. Reduces
engine noise and oil consumption through piston rings and valve guides.
It swells rubber seals or at least makes them more pliable.
You may be thinking of Motor Honey or STP?
