However, the same truck used for hauling heavy trailers across varying temperatures would benefit significantly from a synthetic blend with a robust additive package. Choosing the correct viscosity ensures the engine is protected whether it is started on a freezing morning or run at highway speeds in the heat of summer.
Maximizing Longevity: The High Mileage Diesel Oil Advantage
Conventional Blends When deciding between synthetic and conventional mineral oil, the performance gap has narrowed, but the differences remain significant. Consequently, diesel-specific formulations are engineered with enhanced detergents and dispersants to manage these byproducts, ensuring the oil remains effective throughout its drain interval.
Turbochargers and After-Treatment Systems. In cold climates, a thinner oil (indicated by a lower "W" number) is critical because it flows more readily at startup, reducing wear on critical components like the turbocharger and bearings during the warm-up phase.
Maximizing Longevity: High Mileage Diesel Oil Benefits
Conversely, in hotter climates or during heavy towing, a thicker oil (indicated by a higher second number) maintains a stable film between moving parts to prevent metal-to-metal contact. The CK-4 and FA-4 designations represent the latest generations of diesel oil, formulated to handle the tighter tolerances of modern engines and after-treatment systems like Diesel Particulate Filters (DPFs).
