I am sure there has to be a happy medium between too much and too little.
I would think that too much oil in the box would be detrimental with power hogging and syncro sleeve operation. Remember though that when the gearbox is operating the level drops due to having the oil splashed around the gearbox internals - there will be no part left untouched by the oil. I dont believe there will have to be an 'exact' amount of oil. How many of you have heard of box failures due to either low oil or excessive oil?

Ive just checked a Renault box and see that the filler hole is about half an inch above the output shaft centre line. So what ever level this turns out to be (about 4 litres I think from last measurement) would be a good compromise between too much and too little.

I would like to hear Wannis take on this oil level thing, as I have seen him chat about such issues in the past. Mind you where is he? I havent seen him around here lately?
