Changed right at 3000 miles (book says every 10k?). I had read all of the posts on here that indicated using quart(s) of oils, and checked mine up to the day that I took to the dealer for oil change and did not use a bit. While there, I asked for a quart of oil to take with me in case of use "since it is hard to find" but didn;t tell them specifics, and they brought me the correct oil. Just kind of a check, since they will not allow people in the garage area.
