Confused/Synthetic Oil 700 1987

Please, over look the last message.

I'm the 3 month first time Volvo owner of a 1987 760 sedan turbo 4cyl..ther is a slapping or knocking sound comming from the motor.

I want to try Mobil 1 or some other synthetic oil. Some so called mechanic's are telling me older cars cannot use synthetic oils,they will erode bushings,gaskets and seals.

Can someone tell me without a doubt what's true.

Thanks

P.S.Ther's also a humming noise from the inside
