I change my own since it saves quite a bit of money and I don't trust others to take as much care with my vehicles as I do. I take advantage of Mobil 1 rebates about twice a year when the oil is also on sale at a store and I pay about $2 per quart of synthetic. One of our vehicles takes 7 qts and my cost is under $20 with filter. I really don't mind changing oil it's not so bad or dirty as some make it out to be.
