I just did the second oil change on the Prius. As the oil analysis shows, I used Mobil 1 5W-30 Clean 5000 oil on this change and drove 13,000 miles. I had a Purolator Pure 1 filter on it the whole time. Looks like I went a bit too far.
I filled up with Mobil 1 0W-30 synthetic and a Fram Tough Guard filter. I did clean the air filter when I changed the oil since I noticed it was fairly dirty. I'll probably just replace it now that I got the report back. I'll probably pull a sample @ 10k miles with the synthetic to see how its doing and see how much farther I can push the synthetic.
