Basically nothing I hope means you had something showing on the stick. The reason it shutdown like that was to protect the engine from damage while allowing you to limp it home. By pulling over and getting it towed you gave yourself the best chance not to kill it if something was about to let go. I would think as long as there was some oil in there you've got a fighting chance that the issue is not catastrophic. If it took 5 liters and was not way overfull then I would not feel too good about it.
