i change my own oil, but some people fail to add in the time it takes to purchase your oil and filters(i'm cheap and usually drive around to a couple places for the best deal) and taking your oil somewhere to have it properly disposed of. you don't have to do this everytime, obviously, but just saying that it's not fair to compare a quick change place to doing it yourself without adding in this 'time' factor. anyways, i usually do save money because i like to use synthetic, nice filters, and always look for the best deals.
