Sending your Oil to a lab is like twice the cost of a typical Oil Change. But, you might try extending the Oil Change for one year and then sending in an Oil Sample to the Lab.
If the the lab tells you the Oil Sample is still good to go you can increase your Oil changes time to once a year and in the long run save youself some money and the labor on the oil change.
Someone who knows about synthetic Oil might want to comment on if full cynthetic Oil would allow the Oil change to be extended beyond a year.

With these cars and I think IDI diesels in general, it isn't the oil wearing out that requires the change, it's soot loading reaching max thresholds. So whether dino or synthetic, without significant extra filtration to remove the soot, OCI will remain the same.
