Gearbox Oil Specifications

I need a definitive answer on the full specifications of the gearbox oil that is recommended for a 2008 Clio 197.

I know it’s a 75w-80 and it will take about 2 liters to change.

What I don’t know is if Renault specifies a GL4 or a GL5 oil?

I’ve looked on Opie Oils website and they recommend both GL4 and GL5 oils.

So what’s the correct answer?
