High mileage oil in a bike

[-Clayton-]

Good idea or not?

I thougt about trying some in my old kawasaki kz400 just for experimentation. And since I have run everything from 5w30 too 20w50 including 15w40 delo I didnt figure it would hurt anything since the bike refuses too die or even so much as slip the clutch.

I might even run some 5w20 in it.

Run some GTX 10w40 High Mileage in it and twist the that throttle!
