It's almost always a good idea to change the oil immediately after buying a used car. As an example, I bought my Accord with 90,000 miles on it and the salesman told me that he would have the oil changed before I picked it up. He lied, the oil was dark after the 65 mile drive home. The next OCI was 4000 miles with an HDEO, and the oil barely changed color.
