If it has the starburst symbol on it and says "API grade SN' on it, it's ok for use with any gas engine, flat tappet or roller cam, excluding engines with the high lift aggressive profile camshafts and high pressure springs.
Could you give a definitive step-by- step "how to" for a novice to follow to determine if their motor indeed has a "high lift aggressive profile camshaft and high pressure springs" so they don't use the wrong oil and wipe a camshaft lobe?
That would be most helpful.
