Owners manual calls for 10w40 but 10w30 is acceptable within certain temps. I've seen the Kawasaki oil but it is semi-synthetic and most other 10w40 full synthetic is of the high mileage variety. And other Full synthetic oil of 10w40 is motorcycle specific. I'm not sure either of the Motorcycle or high mileage is suitable for lawn mower use. So I'm thinking of just using 10w30 if I can't find 10w40.. Can anyone here tell me what they are using.
