<human>: I have a friend who is having a problem with his car. What can I tell him to try to help him?
<bot>: One possible suggestion would be to check the oil and make sure it is at the proper level. You could also suggest that he take the car for a diagnostic test, which might provide more information about what's wrong. If the car still seems to be having issues, you could recommend that he take it to a mechanic for further inspection.
