Your engine may be running rich, which could be caused by a bad fuel pressure regulator. If the regulator goes bad you may be dumping way too much fuel than the engine can burn. When that happens the extra fuel gets washed down into the crankcase and dilutes the engine oil.
I would recommend testing the fuel system to determine if either the regulator or injectors are leaking down.
Once the problem is fixed be sure to change the engine oil and filter right away.

you didn't say if the motor starts right away or not. if it is starting well then listen to jarhed. if it cranks over too long too often then it is like pouring gas from a bottle straight into the cyls. being unburnt, the gas, under compression will go through the rings, wash any oil off the rings and let even more gas into the pan. if a car today doesn't start within about 20 seconds, chances are its flooded. keep cranking too much longer and the gas has to go somewhere

When ever you ask a question about your car you should always give the year and model. So I will give you a general answer. You might have a stuck float in your carburetor which is dumping fuel into your cylinders and washing down the sides into the oil. You should have your spark plugs removed and see if they are wet meaning unburned fuel and the possible cause.

Most often, worn rings allowing gasoline to drain past them and contaminate the oil. You can tell pretty easily if this is the problem by observation. Are you seeming to lose power? Has your fuel mileage dropped? The other way would to have a compression test done. I would almost bet you have low compression in one or more cylinders.

Your rings need replaced, they are allowing fuel into your oil sump. Get to a repair shop quick b4 it does more damage.

Like someone else said its running rich. Get your car into a shop to get it checked and repaired before the damage gets worse.
