Diesel engines operate at higher temperatures and pressures than gasoline engines, producing more soot and other combustion byproducts. These contaminants can form deposits on critical engine components, such as injectors, valves and pistons, leading to reduced performance, increased wear and potential engine damage. NAPA Fleet High Detergent Motor Oil 15W-40 Diesel Engine is a specialized lubricant formulated to meet the unique demands and challenges of diesel-powered vehicles.

NAPA Fleet 15W-40 Diesel Motor Oil contains a higher concentration of additives compared to regular motor oils, enabling it to effectively remove and suspend harmful contaminants that accumulate in diesel engines. By suspending contaminants, our fleet oil prevents particles from adhering to surfaces and causing problems. It also helps to neutralize acids and other corrosive substances produced during diesel combustion, protecting engine components from corrosion and premature wear.

In addition to its superior cleaning abilities, this high detergent diesel engine oil provides enhanced protection against oxidation, thermal breakdown and viscosity loss. It maintains its lubricating properties even under extreme operating conditions, ensuring optimal engine performance and longevity. Using NAPA Fleet Diesel Engine High Detergent Motor Oil 15W-40 is particularly beneficial in applications involving heavy loads, frequent towing and dusty or polluted environments. It helps to extend oil change intervals, reduce maintenance costs and ensure the reliable operation of diesel engines. Overall, this diesel engine detergent oil provides exceptional cleaning, protection and performance, helping to keep your vehicle running smoothly and efficiently for longer.
