Description
During engine break-in, your fresh build needs elevated zinc and anti-wear protection that standard oils simply don’t provide. Redline’s break-in additive delivers the critical boundary lubrication your new rings, lifters, and cam require while they’re seating—preventing premature wear and micro-scoring that can compromise performance for thousands of miles. This is essential insurance for any engine that’s been rebuilt, stroked, or freshly assembled.
