Synthetic motor oil

hi,

I am a proud owner of a 1992 500E with low mileage and which i keep maintained and serviced by the authorized Mercerdes-benz dealership here in Lebanon.

since I bought the car which is second hand,I have switched the motor oil to fully synthetic; Mobil 1 (10W-50W) to be specific.

I am wondering if Mobil 1 synthetic Oil has advantage over coventional motor oil in terms of engine protection.

happy to get any idea about that.
