Mobil 1 15w50 should not cause leaks - I ran it for ~5 years with zero
leaks in my 2.1 WBX. Your most likely source of leak is the VC gasket,
followed by front and rear seals. Rear seal leak will destroy your clutch
over time, and front seal leak can affect the timing belt, so don't ignore
them! (btdt, just did my clutch for this reason)

Replace the VC gasket with a rubber one, if not already, then wash the
engine and watch for source of leaks.
