Gearbox oil fill amount

[Smithy111]

I’ve read all the advice on filling the c35 with 3l of oil over the recommended 2.25l the factory recommend but can anyone tell me how much oil would be in the box when the cars on the ground and the fill/level plug removed and oil is at that level? I’m trying to work out how much to add to make the total 3l as a top up

Should be 2.25L in the 'box when level.(Slow drip out of the proper bolt on the side)

 

So, add another 0.75L. (Simple? Not if you suffer from Math Anxiety) 😵

This is what I had assumed but you know what they say about assumptions! Cheers I’ll do exactly that
