In this month’s edition of the AMSOIL Magazine, on page 7, Mark Nyholm, Technical Product Manager of Heavy Duty, discusses how the API will introduce two new diesel specifications in December: CK-4 and FA-4.
 
Also, on page 9, AMSOIL discusses how a motorcycle wet clutch works.  Wet clutches are widely used in motorcycles and dirt bikes.  The term simply means the clutch is lubricated with oil, as opposed to a dry clutch.  A wet clutch typically lasts longer and is more forgiving to operate than a dry clutch.
