シビアコンディションの正体 ── 部屋干しの洗濯物と同じことがエンジン内部で起きている

This time, we'll discuss the intricacies of "rust prevention," a topic that even the most dedicated enthusiasts cannot overlook. Question the common belief that "rust won't occur if it's immersed in oil." The inside of an engine is subjected to a wave of attacks from sulfuric acid and nitric acid, combustion byproducts. This video logically explains the physical limitations of base oils and the chemical behavior of the additive package that complements them. ■ Technical Topics in This Episode The Mechanism of Acidification and Sulfur Content in Fuel Even with "sulfur-free" fuels (JIS standard 10 ppm or less), NOx-derived nitric acid generation is unavoidable. "Evaporation," Not "Boiling"—A Thermodynamic Perspective on Moisture Management Why is 85-95°C the "golden operating range"? Learning from the laundry drying process: the coordination of blow-by gas and PCV valves. The Additive Team's "Chemical Correlation Diagram" Detergent Dispersants: "Foundation Building" for ZDDP Film Formation and Acid Neutralization. ZDDP (Zinc Dithiophosphate): Not only prevents wear, but also provides a rust-preventive barrier through a tribofilm. Antioxidant: Stops the generation of organic acids upstream. Why a universal oil with both "SP/CF" markings? The logical benefit lies in adding the powerful acid neutralization capability (equivalent to CF standard) derived from diesel engines to the modern SP standard. ■ Understanding the Specifications: TBN (Total Base Number) Lifespan TBN is an indicator of the oil's "neutralization capacity." How does this meter degrade with mileage? A former engine tuner warns about the fatal damage that "TBN depletion" can inflict on metal surfaces under severe conditions. ━━━━━━━━━━━━━━━━━━ 📺 Related Videos to Deepen Your Knowledge ━━━━━━━━━━━━━━━━━━ In-depth Explanation of the Five Functions of Engine Oil • [Cooling] Polymers Were Making the Engine Hot [The Inconvenient Truth About Synthetic Oils]    • 【冷却編】ポリマーがエンジンを熱くしていた｜合成油の不都合な真実   • [Lubrication] I Believed in the Lubrication of Synthetic Oils for 20 Years, But It Was All Wrong    • 【潤滑編】20年間信じてた合成油の潤滑性、全部間違いでした   • [Cleaning and Dispersion] Polymers Were the Culprits of Sludge | The Additive with the Worst Soot Dispersion Performance    • 【清浄分散編】スラッジの犯人はポリマーだった｜すす分散性能が最も悪い添加剤   • [Sealing Chapter] Sealing is Created by Viscosity | The Mechanism by which a Thick Oil Film Stabilizes Piston Rings    • 【密封編】密封は粘度で作られる｜厚い油膜がピストンリングを安定させるメカニズム   🛡️This video explains: "Why you shouldn't apply the same oil standards to classic car engines as to modern cars." The reason is explained from the perspective of structure and design philosophy. Classic cars and new cars have completely different engine preconditions: Clearance width, magnitude of thermal deformation, and rate of wear. However, many engine oils currently on the market are designed based on new cars. Our non-polymer mineral oil is the opposite. It is made with a design philosophy specifically for classic cars, clearly defining "what to include and what not to include" by working backward from the weaknesses of classic cars. • Non-polymer design that doesn't mask viscosity • Achieving both airtightness and cooling performance with Group II mineral oil • Enhanced boundary lubrication with metal shield • Design that prevents additive runaway and addresses the root cause of heat-related performance degradation It's not just "mere" mineral oil. Mineral oil is constantly evolving. Only with this comprehensive design can you truly protect your classic car's engine in the long term. We hope this video will provide you with the "right information" to help you continue driving your beloved car for many years to come. ━━━━━━━━━━━━━━━━━━ 🛡️ The only way to protect against "structural defects" ━━━━━━━━━━━━━━━━━━ The engine's blueprint (structure) cannot be changed. That's why only the "blood (oil)" you put inside can save the engine from this heat hell. ▼【1. Know the Enemy】What exactly is "heat-related performance degradation"?
