Red Line Engine Break-In Additive provides conventional motor oils with anti-wear additives like zinc and phosphorus (ZDDP) that are necessary to protect against premature camshaft and valvetrain wear. While designed for optimal engine break-in, this formula is ideal for extra anti-wear protection at any time.
- 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
