Recommended oil grade for std engine is a 5w30 most BPU and higher mileage engines use a 10w40, personally I would only use a 5 or 10w50 on an extremely worn or very highly stressed motor IE pushing high BHP, running much higher viscosity oil just adds to the stress on the oil pump and pressure relief valve.
