Just added the 2007 Accent to my garage. Has the 1.6L four cylinder in it. Just turned 36k miles on it, and has an unknown maintenance history. Does not appear to be abused, however. I only put about 5 to 6k miles annually on my car, so have gone to a 6 month OCI on the Accord, which will be replaced by the Accent. My guess is continue the 6 month OCI with either PYB or Mobil Super 5000? Ideas?
