Required Oil Brands for Use with MWSC Flat Tappet Camshaft & Lifters for a Kohler Command motor for Pulling

Wear protection reference categories are: 

• *** Over 90,000 psi = OUTSTANDING protection 

• *** 75,000 to 90,000 psi = GOOD protection 

• *** 60,000 to 75,000 psi = MODEST protection 

• *** Below 60,000 psi = UNDESIREABLE

The higher the psi number, the better the wear protection.
