Motor Oil, Engine Oil Break-In Zinc Additive, ZDDP, 16oz.

Provides conventional motor oils with antiwear additives like zinc and phosphorus (ZDDP) necessary to protect against camshaft and valvetrain damage on break-in. For flat tappet(lifter) applications it is suggested to add this with every oil change to help prevent premature failures.

• Allow pistons rings to seat properly with less-slick oil, while antiwear additives protect other engines components to avoid excessive wear
• Can also be used in conventional and synthetic oils during regular operation, providing an extra package of protection otherwise not found in most motor oils
• 16oz bottle treats up to 12 quarts of motor oil--in many cases, one bottle can serve three engines or oil changes
