Have you checked the oil level in the engine?

I'd check you got the right filter on it, the oil filler cap is back on tight, and, as ytlas suggests, oil level.

Both of the answers previous give to you are good ones check to make sure you have the right filter on and the right oil it should be 5w/30.
