Hi there,
this is condensation building up in the engine, you are probably not doing a lot of miles, I would say many short trips, the engine is not getting up to normal operating temp often enough to burn off this moisture properly. Add a tin of engine oil flush and go for a long drive, change the oil & filter, this will help but will not solve your problem, getting the engine up to full temp often will be the best thing to do.
