I've been using Castrol Syntec 5W50 for the past 3 or 4 years in my TR6.
My dad uses it in his Stag,and my brother uses it in his Spit/GT6 hybrid.
None of us have ever had problems with leaks. I don't really see how a
synthetic oil would contribute to increased oil leaks. I suppose the fact
that the viscosity of the oil is less would allow it to leak out a bit more
easily, but I doubt it's that bad. Considering the benefits of lower cold
start up viscosity, I'd say a bit of leaking is worth it.
