evening bud!, that could mean a number of things, the oil light coming on is a indication the oil pressure has dropped , therefore not pumping oil around the engine, which then runs the internals of the engine dry where they then pick up on the bearings and start chewing/ruining the engine , next step i would do is drain the oil and take a look at it, see if theres like a metallic kind of a shimmer to it? this would give me an indication on how bad things have got. not really any good outcome to this imo i'm affraid.
