Oil light going on and off in W202 C230k.
If it's just a puff of oil on start up, probably valve stem seals. If someone drives behind you, get them to check if the oil stream from the exhaust is constant. You would smell it anyway. Also, pulling the plugs and seeing their condition will also tell you.
From the amount you were down in the short period of time, I would expect there would be a cloud of blue smoke, and not a puff.
