Oil??

I'm using Amsoil 15w-50 "racing" oil. It has a lot of zinc in it. Zinc is needed to protect your flat tappet cam! but, bad for your catalytic converter. Not really a big issue here. :-D

If you don't want to spend $11 a quart for racing oil. Use motorcycle oil.
Motorcycle oils are very high in zinc and are not government restricted to their zinc content.


I hope I haven't opened the zinc content Can Of Worms.
