What's happens if somebody puts 6 1/2 qts in when it only holds 5

The stick reads I'm a half qt low

There's oil all over the bottom like it was squirting out and the stick read 1/2 qt low before I noticed that

sounds like the old oil filter o ring was left on oil adaptor during oil change and the oil is leaking out between the old and new o ring. thi shappens at times to people that don't pay attention while working

Thanks I'll take a look at it
