A healthy dose of ZDDP is essential for breaking in a motor. We also know that motor love ZDDP for long term use as well, especially in a 2ZZ-GE Toyota engine!

Great Features of this Additive Include:

• Provides conventional motor oils with antiwear additives like zinc and phosphorus (ZDDP) necessary to protect against camshaft and valvetrain damage on break-in
• 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 two engines or oil changes.
• Use Redline Break-In additive in larger quantities to break in your motor and small quantities when using conventional “street oils" to bring up the ZDDP content in the engine oil. Break-In additive is not recommended if already running ZDDP rich race oils such as Redline Race Oils.

This is a single 16oz bottle of Redline ZDDP Break-In Additive
