Manual says 10,000. Folks who have had their oil tested say 6,000-7,000. With that many miles I wouldn't go farther than 5,000. Maybe less. Depends on how long you plan to keep her.It’s about half way on the stick between low and full. I was surprised by how burnt looking the stick is. I always have had my oil changed at the dealership. Btw, the manual I think said to change every 10,000 miles? Is that right?
