I'm about to change the oil in my Ninja 500. I was told that it had Mobil 1 synthetic in it now. I was just going to replace it with some Castrol Syntec 10-W40, but a motorcycle buddy of mine told me that automotive oils shouldn't be used in bikes due to foaming properties (I guess from the gearbox foaming up the oil?).
Is this true? What should I be using. He knows a lot, but he is also super anal about his bikes, so I dont know.
Thanks,
**** newbie.
