VP Racing, Racing Oil, Break In 10w-40, 946ML Bottle (PART #VP-2417)

The formulation of engine break-in oil is what differentiates it from traditional motor oil. Typically, break-in oils are conventional-based lubricants. Often, they contain zinc/phosphorus (ZDDP) plus moly anti-wear chemistries. ZDDP creates a polar attraction to surfaces in the engine. It also creates a sacrificial layer to prevent metal-to-metal contact in areas where a full-fluid oil film cannot exist. For example, between cam lobes and lifters. Molybdenum disulfide is a sulfate-based additive that serves three purposes: it protects against corrosion, oxidation, and reduces friction. This allows the break-in oil to control friction in low-load areas, such as piston rings. Furthermore, it provides exceptional protection to areas with high loads, such as the camshaft and lifters. As a result, the controlled wear inside the cylinder prevents oil from being burned off at an increased rate due to oil building up between the piston and cylinder. It is important that the break-in oil contain an aggressive detergent/dispersant package to trap contaminants and metal particles, keeping them away from engine parts. Another key point is that engine break-in oil assists in the designed wear process (breaking in"), so that future fills with regular engine oil, can maintain ongoing protection of the engine. PERFORMANCE ADVANTAGES OF VP BREAK-IN ENGINE OIL Multi-viscosity conventional oil blend Balanced level of ZDDP and moly anti-wear additives Shear stable polymers to prevent viscosity loss during break-in process Aggressive detergent/dispersant additive system Ultimate protection for flat tappet and roller cams Use for initial 15-20 dyno pulls or 50-100 road miles
