Is possible that a too rich mixture causes gasoline leak into the oil ?
Thanks in advance

The petrol injectors should shut off on LPG so you shouldn't have fuel in the crankcase. You need to do a pressure check on the fuel rail, see how long it takes for the pressure to drop off after switching the engine off, it should hold pressure for at least 20 minutes. Less than that and it pints to one or more petrol injectors leaking, possibly when the car isn't running or it would show a rich mixture on both LPG and petrol, bringing the Engine Management Light on.
