Engine oil costs can vary depending on several factors, including the type of oil, its formulation, brand reputation, and market demand. Here are some reasons why engine oil prices may be higher in recent years:
Advanced Formulations: Modern engines require high-performance oils that meet stringent specifications to provide optimal lubrication and protection. As engine technology advances, oil formulations have become more complex, incorporating additives and synthetic base oils to meet the demands of turbocharged engines, direct injection systems, and emissions regulations. These advanced formulations often come at a higher cost.
Quality Standards and Certifications: Engine oil manufacturers must adhere to quality standards and certifications set by industry organizations and vehicle manufacturers. Meeting these standards requires rigorous testing and quality control measures, which can contribute to higher production costs.
Environmental Regulations: Environmental regulations aimed at reducing emissions and improving fuel efficiency have led to changes in engine design and oil specifications. Newer engine technologies, such as gasoline direct injection (GDI) and turbocharging, place greater demands on engine oils, requiring oils with enhanced thermal stability, shear resistance, and deposit control. Formulating oils to meet these requirements may result in higher production costs.
Market Demand and Supply: Fluctuations in crude oil prices, supply chain disruptions, and changes in market demand can impact the cost of raw materials and manufacturing processes, ultimately affecting the retail price of engine oil.
As for Dexos D oil, it is a specific type of engine oil formulated by General Motors (GM) for use in their vehicles equipped with diesel engines. Dexos D oil meets GM's stringent performance requirements and specifications, ensuring compatibility with GM diesel engines and providing excellent lubrication, wear protection, and engine cleanliness.
The key features and benefits of Dexos D oil include:
- Enhanced thermal and oxidation stability: Dexos D oil resists thermal breakdown and oxidation, maintaining its viscosity and lubricating properties under high-temperature operating conditions.
- Improved deposit control: Dexos D oil helps prevent the formation of deposits on engine components, such as pistons, rings, and valves, ensuring optimal engine cleanliness and performance.
- Compatibility with emissions control systems: Dexos D oil is compatible with diesel particulate filters (DPFs) and other emissions control devices, helping to maintain their efficiency and longevity.
- Extended drain intervals: Dexos D oil may allow for longer oil change intervals compared to conventional oils, helping to reduce maintenance costs and downtime for fleet operators and vehicle owners.
Overall, Dexos D oil offers superior performance and protection for GM diesel engines, making it a preferred choice for GM vehicle owners and fleet operators. It is also REQUIRED to be used in all new 3.0L GM Diesel engines for warranty purposes.
