    • API Service Classification:
    • The API (American Petroleum Institute) service classification is a system used to categorize the quality of diesel engine oil. Higher API classifications indicate better quality. Thus, when buying 15w40 diesel oil, search for products with API Service Classification of CI-4 or higher. These products are designed to deliver the highest level of performance and protection for diesel engines.

    • Brand Reputation:
    • You do not have to buy from expensive brands to get high-quality products, yet choosing a reputable brand when buying engine oil is essential. Brands with a long-standing history of producing high-quality products are better choice for your engine.

    • Price:
    • It is always tempting to save money and go for the cheaper 15w40 diesel oil, but before you do that, remember that quality is not cheap. The cost of 15w40 diesel oil comes from the costs of production and the costs of marketing.

      To save money, choose a known brand with a good reputation. Using high-quality engine oil has a direct impact on the performance and lifespan of your engine. In other words, buying high-quality oil is an investment and not lost money.

    15w40 Synthetic Diesel Oil Vs. Mineral Diesel Oil

    You have two products with the same API and brand, but one is mineral while the other is synthetic. It could be a tough decision, so how do you choose?

    Conventional 15w40 Diesel Oil

    Conventional diesel oil 15w40 is made from refined crude oil that is blended and treated with additives to enhance its performance.

    15w40 Synthetic Diesel Oil

    15w40 Synthetic Diesel Oil, on the other hand, is made through a more advanced refining process that produces a purer form of oil. Synthetic oil is treated with high-performance additives to further enhance its properties. Unlike conventional oil, synthetic diesel oil has a uniform molecular structure which makes it more resistant to breakdown and oxidation, providing better protection to the engine.

      15w40 synthetic diesel oil is better when you have a car with newer engines and want more protection. The cost of synthetic oil is higher, but it is worth it.
