Hello Kawafreunde meine liegen geht um die Ölkendung Se,Sf,Sg etc. I made an oil change at the EL250 and did not consider whether the oil of Kawasaki was released. According to the operating instructions the oil type of the SE or SF class should correspond. But I now have 10W40 SG tipped in!! Should I let this off again, can the engine suffer from it if I leave it in? What does it have with the SE,SF etc. on it? Don’t know me there, can you help me? I greet you The Chicken
