Diesel engines have different functional requirements than conventional gasoline-engine-powered vehicles. Diesel engines have two primary purposes, the first being the power to drive the wheels and the second being the motive force to propel the vehicle. The diesel engines in heavy-duty trucks and trailers have this second purpose, called motive power. The heavy duty diesel engine oils must perform at all speeds, sustained use, and several different cranking cycles, idling, and starting. They must not allow hydrocarbon to seep through, or the engine will not run properly. They must provide adequate cooling under both warm and cold operating conditions. Thus, below are some of the benefits of selecting the best heavy-duty diesel engine oil.

Better Performance :- Unlike conventional motor oils, diesel engine oils are often formulated to promote lower energy consumption and higher performance in a wide variety of applications. Engine oils need to survive the rigors of heavy-duty operation for many years with high performance. The decision to develop heavy-duty diesel engine oils came from a desire to find the best motor oil to improve performance and maximize engine life.

Better Mileage :- While modern diesel engines have changed significantly over the past 40 years; they still suffer from common oil quality issues that cause wear and degradation of engine parts. Diesel will not typically run as efficiently as gasoline engines when first started due to the lack of oil used for lubrication. Manufacturers recommend pre-conditioning of the engine to prepare it for the startup procedure, which an oil change may follow before the end of the week. However, most heavy-duty diesel engine oil suppliers offer complete engine oil maintenance programs designed to resolve common engine oil problems.

Protects wear and tear of the engine :- Reduces carbon dioxide emissions by reducing fluid displacement (aerodynamic drag) in the cylinders during startup and by reducing the amount of fuel needed for combustion during idle periods. Heavy-duty diesel engine oil delivers improved power and durability and also increases horsepower and torque while reducing fuel consumption and the need for frequent fuel stops. Moreover, improved fuel efficiency is associated with increased idling time as well as decreased emission of gaseous pollutants (NOx and CO2). Eliminates the risk of cylinder walls cracking due to heat. Cylinders can crack due to the heat from high-temperature fuels. Manufacturers, therefore, make periodic changes to their oil viscosities and oil additives to compensate for the effect of this risk.

Protects from corrosion :- Iron from the input diesel fuel oil corrodes parts of the engine oil. To protect the engine from corrosion, the different base oils have additives that combine with sulfur. Each fuel engine manufacturer offers a base oil that meets the requirements of its specific model. This often means that there are different base oil options available for different model year engines that have different system and injector injection levels.

While diesel engines can be found in many non-diesel applications such as forklifts and municipal transport, none can match their power and reliability compared to their gasoline-based counterparts. In addition, combustion products generated by diesel engines are significantly cleaner than those generated by gasoline engines. Having the Best Diesel Engine Oils for your application can make a real difference in your fuel mileage.
