Motul 1QT Classic BREAK-IN OIL 10W40 (Part# mot2810QTA) - Single

Motul Classic BREAK-IN OIL 10W40 | High-Performance Engine Break-In Oil

Ensure a proper break-in for your classic car engine with Motul Classic BREAK-IN OIL 10W40. This high-zinc, high-phosphorus formula (ZDDP) optimizes piston ring sealing and protects critical engine components during the crucial break-in period. Perfect for rebuilds and new engine builds.

Motul Classic BREAK-IN OIL 10W40 (Part# mot2810QTA) is a specialized engine lubricant formulated to facilitate the critical break-in process for newly rebuilt or new classic car engines. This high-performance mineral-based oil is enriched with an exceptionally high concentration of Zinc Dialkyl Dithiophosphate (ZDDP), a crucial anti-wear additive. The high levels of zinc and phosphorus create a sacrificial layer on camshaft lobes, lifters, and other valvetrain components, preventing premature wear during the initial startup and high-load cycles.The carefully balanced viscosity of 10W40 ensures excellent lubrication across a wide range of temperatures, while its low detergent formula allows for the controlled wear necessary for proper piston ring seating against the cylinder walls. This process is essential for achieving optimal compression and long-term engine performance. Unlike modern oils that have reduced levels of ZDDP to protect catalytic converters, Motul's Classic BREAK-IN OIL is designed specifically for older engines that lack this sensitive equipment and require the added protection. This product is ideal for flat-tappet camshafts and other vintage engine designs. Each single quart bottle provides a convenient and effective solution for a single oil change during the break-in period.

Best Uses

1. Engine Rebuilds: Ideal for the initial break-in of a freshly rebuilt engine to properly seat piston rings and protect internal components.
2. New Engine Builds: Use for the first few hundred miles on a brand-new engine to ensure optimal wear and performance.
3. Flat-Tappet Camshafts: Highly recommended for engines with flat-tappet camshafts, which require high levels of ZDDP to prevent premature wear.
4. Classic and Vintage Cars: Specifically formulated for classic vehicles that were originally designed to run on high-zinc oils.
5. Performance Engine Break-In: Suitable for high-performance applications where a proper break-in is crucial for maximizing power and longevity.

Key Features

1. High ZDDP Content: Contains a high concentration of Zinc Dialkyl Dithiophosphate (ZDDP), a powerful anti-wear additive essential for protecting vintage valvetrain components.
2. Low Detergent Formula: Allows for controlled wear during the break-in period, facilitating proper piston ring seating and sealing.
3. Mineral-Based Oil: A high-quality mineral formula that is compatible with the materials and tolerances of classic engines.
4. 10W40 Viscosity: Provides a balanced viscosity that ensures excellent lubrication and protection across a wide range of operating temperatures.
5. Optimizes Piston Ring Sealing: Formulated to promote the necessary wear between piston rings and cylinder walls for achieving maximum compression and performance.

 Key Benefits

1. Extends Engine Life: By protecting critical components during the crucial break-in phase, it helps to ensure the long-term health and durability of your engine.
2. Prevents Premature Wear: The high ZDDP content provides a sacrificial layer on metal surfaces, effectively preventing scuffing and damage to camshafts and lifters.
3. Maximizes Engine Performance: Promotes proper piston ring sealing, which leads to optimal compression, increased power, and better fuel efficiency in the long run.
4. Reduces Risk of Engine Failure: A proper break-in process with the correct oil significantly reduces the chance of catastrophic engine failure early in its life.
5. Specifically Designed for Classic Engines: Provides a modern solution that respects the needs of classic and vintage engines, offering superior protection compared to conventional modern oils.
