1986 944 Synthetic oil


Vehicle Information: Year: 1986; Engine (type, size, modifications): 2.5L, custom pistons, balanced and blue printed, ++++; Total Mileage: 8000;

I want to change from 20w50 to Sythetic but I have been told varying opinions and wanted one more. I was told that my engine was designed with Sythetic oil not in mind and to switch to it would cause problems with the tolerances in the engine. But, all the cars at the track are running it. What is your take on this and what grade of synthetic oil should I use if I switch?
