Bad fuel pump
Probably is a bad pump but B&S also says to use 30w. You can use 10w30 and even 5w30 but they warn you that oil usage will be up.
Installed new fuel pump,same problem,oil ooses out of screen on front of fuel pump,engine still runs fine.have called sears,tried several forums,still no solution.eventually all oil will be gone from engine then the problem will be gone also.
