What engine ? In the Nissan Murano 3.4 V6 , the oil fill goes into one of the cam covers ( very much like the rocker covers of an American V8). Probably there are small drain holes at each end down to the pan, about 1 to 2 cm diameter. There is a good chance the foreign object will stop there , at least temporarily. Probably there is a screen on the inlet to the oil pump in the pan which will stop a small bit of plastic. So, PROBABLY no problem. The alternative is to pull the cam cover under the fill tube. That does not look like too bad a job on my 3.4 L , a few hours of nuts and bolts. If you find nothing , you could consider dropping the oil pan ; it looks like it could be wiggled out between the exhaust header and the frame on my 3.4 L Murano. In the good old days I would pull both rocker covers on my Olds in 10 minutes , but the covers knew what to do and I had the gaskets arranged so they did not need replacing.
We cannot guess what it was.
What you do is remove the rocker cover or cam cover and see if the piece is sitting there, it will be if you are lucky.
If not, then you have to find it otherwise it may cause serious damage - even if it was only "plastic" it may well block oilways which can cause oil starvation and seizing.
