What you use to Shampoo your carpets/seats?

Any suggestions on a good carpet/cloth seat shampoo to use? I've got some oil spots from mechanics.

Blue Diamond dry clean carpter/upholstery cleaner works real well for about anything I have ever tried it on. They have one in a blue aerosol can with a brush on the top and one that is in a Windex like bottle. The fluid in there is clear. I like that the best and just use a hard bristle brush. It is in auto parts stores like Checkers, Autozone, etc.
