I searched and found several threads about using a motorcycle oil in a mower engine. I don't see it being an issue. I'm wondering if anyone has done it on a regular basis? I have a Kawasaki FR691 and a Honda 400ex that I'd like to use the same oil in. Just trying to keep it simple. If I buy a case of the 10-40 I can change the oil in both. OR buy 3 quarts of separate oil and have a half quart of each left over. Any experience or reasons for or against are welcome.
Thanks in advance!
