Red Line Oil #81403 Motor Oil Additive, Engine Break-In, 16 fluid oz., Each. 

R31-81403

Description:

Red Line's new Engine Oil Break-In additive provides conventional motor oils with anti-wear additives, like zinc and phosphorus, that are necessary to protect against camshaft and valvetrain damage on break-in. This is especially important in flat-tappet engines where bigger camshaft grinds and higher valve spring pressures are now popular. Red Line Engine Oil Break-In additive is designed to allow piston rings to seat properly, while allowing other engine components to avoid excessive wear.

Features:

*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
