With runny stool this long, I'd say take him asap. Ask the vet if you can pay next Weds. - you could even leave a "post-dated" check maybe? Is there blood/mucous? How is his appetite? Are his gums pale? Pale gums indicate dehydration.
Is he a puppy? If so, that makes it even more urgent. Keep me posted!
