Sounds like an injector leak. Even a slow leak will eventually empty the fuel rail into one or more cylinders, and the gas will seep down into the crankcase. I could be wrong, so probably a good idea to use a fuel pressure gauge to watch the pressure after shutting the car down.Also, does the volume of the oil seem to increase? If you don't have an injector leak then maybe you're just running too rich.

I guess I could have an injector leak. I just got the car a month ago so I've only done 1 oil change. I dumped the oil into a 1gallon jug and it was a little less than 1 gallon..What do you mean about the fuel pressure gauge??

Hook a fuel pressure gauge inline between the filter and the rail. Have someone turn the key so the pump primes. Clamp off the feed and return lines to the fuel rail so that the rail and the gauge are isolated. The rail should still be pressurized at this point, and you can read the pressure off the gauge. Sit and watch the gauge to make sure the pressure doesn't drop. If it does, it has to be leaking through the injectors or maybe the clamps aren't holding properly and you need to try again.
