What kind of foundation would you recommend for someone with oily skin?

I just started wearing foundation and I'm 22, and I like the look of it at first anyway. After about an hour, my skin gets so oily that it literally feels like my face is melting off. It's mainly in my T-Zone. I apply it with a foundation brush, and I barely use a dime sized amount for my whole face. I use blotting papers to help, but I've found that by the 5th hour, it looks like I didn't put on makeup at all!! Is there any other type of foundation that you have found that lasts and doesn't cause your skin to get so oily?
