Found this interesting study yesterday from NPD. It ranks the total auto aftermarket service share by outlet, and estimates that quick lubes account for about 15 percent of all DIFM auto aftermarket service. Now, keep in mind that this includes ALL service, not just oil changes, but the figures are still worth noting, especially given that repair and tire shops have made advances in the service arena in recent years, quite often by adding oil changes and other auto maintenance.
