Engine Additives In A C3 1.6 Sensodrive

[lupin]

For the last few years , with my other cars, I've been impressed by a friction-reducing engine oil additive called ZX1. I'm not quite clear, however, if the engine oil in the petrol 1.6 litre C3 sensodrive is shared with the auto gearbox/ clutch mechanism, and whether using such an additive might consequently be dangerously inappropriate in this car. Anyone know?

The lubrication system in the the C3 is separate between gearbox and engine so additive in the engine oil is ok.

 

Incidently, its a dry clutch as the sensodrive gearbox is a manual unit with a couple of large motors bolted on to change gear and operate the clutch
