In general most people wouldn't recommend synthetic oils in a LR engine of this age, as they tend to leak out rather quickly. Although you can get synthetics which are just as thick as mineral oils, they are prone to something called "capillary creep", which means they look for ways to escape your engine, without paying much attention to their viscosity. The engine was designed for mineral oil, so I'd keep using normal oil and make sure you change it regularly.
