Yep, as others have said, don't drive it at all until it's sorted otherwise you'll bugger your engine. I'd open the sump up to check a few things. As others have said, check the pickup, usually fine if it's spent it's life on synthetic oil but you can also inspect your oil pump and chain and have a bottom end inspection. If you're handy with tools, this is dead easy to do. You'll need some gasket sealant for the sump too, from dealers or TPS.
