Still waiting for 3rd party testing proof that API SN Ultra has a NOACK that low. That's still up in the air.
You are also sacrificing frictional coefficient and efficiency with Ultra since it's a hydrocracked petroleum product.
Can you point to third party testing confirming Amsoil's Noack? Ultra's base stocks are GTL-derived, so not hydrocracked petroleum, at least as I understand the term.
