The reason for changing would be the fact that Silkolene PRO R 15w-50 contains ester basestocks as well as PAO.
These have some great advantages:
Esters
All jet engines are lubricated with synthetic esters, and have been for 50 years, but these expensive fluids only started to appear in petrol engine oils about 20 years ago. Thanks to their aviation origins, the types suitable for lubricants (esters also appear in perfumes; they are different!) work well from 50 degC to 200 degC, and they have a useful extra trick.
Due to their structure, ester molecules are polar; they stick to metal surfaces using electrostatic forces. This means that a protective layer is there at all times, even during that crucial start-up period. This helps to protect cams, gears, piston rings and valve train components, where lubrication is boundary rather than hydrodynamic, i.e. a very thin non-pressure fed film has to hold the surface apart. Even crank bearings benefit at starts, stops or when extreme shock loads upset the hydrodynamic film.

Pro S 10w-50 is a good grade for performance/track cars, Pro S 5w-40 is a good grade for road cars.
I always highly recommend the Silkolene PRO S as it's a top product.
