Benefits of Using 15w-40 Choosing the correct oil offers numerous benefits for engine longevity and performance. The thicker 40-weight characteristic provides the robust protection needed for high-compression diesel cycles.
As the engine warms up, the oil thickens to the 40-grade consistency, maintaining adequate lubrication and preventing metal-to-metal contact. Contaminants such as dust, metal particles, and byproducts of combustion accumulate over time, reducing the oil's effectiveness.
