BluePrint Engines - 10w30 Engine Oil Quart

BluePrint Engines' 10W30 Engine Oil is specifically formulated to address the wear and contamination concerns of high-performance engines. This mineral-based oil contains elevated levels of zinc (1,800 ppm) and phosphorus (1,600 ppm) to extend oil film capacity, providing ultimate protection for your engine. Designed for use after the initial 500-mile break-in period, it offers film strength and viscosity stability at higher temperatures, maintains oil pressure and compression, and provides upper cylinder anti-wear protection. Ideal for pushrod, flat tappet, and roller cam engines, this oil is also a top choice for engine storage. ([blueprintengines.com](https://blueprintengines.com/products/bpp10w30?utm_source=openai))
