EXTREME DIESEL ENGINE OIL PROTECTION

AMSOL Ultimat Callout Truck Race

Diesel engines are the workhorses of many industries, their raw power and durability making them indispensable in sectors such as construction, agriculture, and mining as well as in the hyper truck builder world. Given the strenuous conditions these engines operate in, they need a powerful synthetic diesel oil that can match their strength and endurance. AMSOIL Signature Series Max-Duty Diesel Oil is designed specifically for this purpose, offering a host of benefits that align perfectly with the needs of both heavy-duty and standard driving conditions.

​

A hallmark of this product is its exceptional capacity to push the extended oil drain interval up to 60,000 miles. The oil's superior stability and longevity mean that it continues to deliver robust protection and performance, far beyond the duration of typical oils. This extended drain interval reduces maintenance downtime, enabling your vehicles to stay operational for longer and deliver continuous productivity, especially in hard working heavy duty industries where AMSOIL 15W-40 is popular.

​

This synthetic diesel oil has been carefully formulated to withstand the rigors of heavy-duty tasks. Whether it's the dusty landscape of a mining operation, the rugged terrain of a construction site, or the intense workload of hauling heavy loads, this oil provides steadfast engine protection. Its robust composition offers superior lubrication, minimizing wear and tear on engine components, and significantly enhancing engine lifespan.

​

Another impressive feature of this diesel engine oil is its high-temperature performance. Diesel engines operating under heavy-duty conditions often generate considerable heat, and this oil’s excellent thermal stability ensures it continues to provide robust protection even under these demanding conditions. This ability to resist breakdown at high temperatures helps maintain engine cleanliness and prevent the formation of damaging deposits, thereby preserving engine power and efficiency, reducing the need for costly auto repair. Take a look at the other diesel oil available to see the options available for your vehicle.

HOW AMSOIL SIGNATURE SERIES HELPS TO ADDRESS COMMON DIESEL ENGINE PROBLEMS

Diesel engines are known for their durability and efficiency, often serving as the backbone of many commercial operations in fleet vehicles, as well as being a popular choice for heavy-duty and long-distance drivers. However, like all mechanical systems, they are prone to certain issues. Understanding these common problems and how the best synthetic diesel oil from AMSOIL can play a crucial role in preventing and mitigating these issues is essential for engine mechanics, fleet mechanics, and motor mechanics alike.

​

Glow Plug Failures: Diesel engines rely on glow plugs for cold starts. These components heat the combustion chamber, aiding in the ignition of the diesel fuel when the engine is cold. When glow plugs wear out or fail, starting the engine becomes challenging, especially in colder climates. Using high-quality synthetic engine oil can help in this regard. The oil’s improved flow at lower temperatures ensures that the engine components, including the glow plugs, are adequately lubricated, minimizing wear and tear and helping the engine start more easily in cold conditions.

​

Fuel System Contamination: Diesel engines are particularly sensitive to contaminants in the fuel system. Water, dirt, and other particulate matter in the fuel can cause significant damage to the fuel injectors and pump. Synthetic motor oils often come with detergents and dispersants that help to keep the engine and its components clean. By maintaining cleanliness, synthetic engine oil reduces the likelihood of contaminants wreaking havoc in the fuel system compared to conventional oil.

​

Oil Oxidation and Thickening: Diesel engines, particularly those used in fleet vehicles, operate under high-stress conditions for extended periods, which can lead to oil oxidation and thickening. This issue can result in reduced oil flow and increased wear on engine components. Synthetic oils have better oxidative stability compared to conventional oils. This stability helps in preventing the oil from becoming too thick and abrasive, thereby protecting the engine parts from excessive wear.

​

Turbocharger Problems: Many modern diesel engines are equipped with turbochargers for increased power and efficiency. Turbochargers operate at high temperatures, which can cause conventional oil to degrade faster, leading to deposits and inadequate lubrication. The best synthetic oil products are designed to withstand these high temperatures, ensuring that the turbocharger remains well-lubricated and free from deposit buildup.

​

Excessive Emissions: Diesel engines can produce higher levels of soot and other emissions compared to gasoline engines. These emissions can lead to the clogging of the EGR (Exhaust Gas Recirculation) valve and the DPF (Diesel Particulate Filter). High-quality synthetic oils are formulated to produce fewer emissions. This property helps in keeping the EGR valve and DPF cleaner, thereby reducing the frequency of maintenance and potential for costly repairs.

​

Soot Buildup: Soot is a common byproduct in diesel engines that can accumulate in the engine oil and on engine components. Accumulated soot increases oil viscosity, which in turn puts extra strain on the engine. Synthetic oils typically have better soot dispersal properties than conventional oils, helping to keep the oil fluid and protecting the engine from the abrasive effects of soot particles.

​

Corrosion: Diesel engines are prone to corrosion due to the high levels of combustion by-products and acidic compounds that can accumulate, especially in engines that go through frequent short trips where the engine doesn't reach full operating temperature. The best synthetic oils contain high quality additives that neutralize these acidic compounds, thereby reducing the risk of corrosion and prolonging engine life.

​

DIY Oil Change and Professional Oil Change Services: For those who prefer a DIY oil change or professional oil change services, using a high-quality synthetic oil can make a significant difference in the health and longevity of a diesel engine. Whether you’re searching for an "oil change near me facility" or planning to perform the service yourself, using a superior synthetic oil ensures your engine gets the best possible care.

​

Using AMSOIL Lookup for the Right Oil: Choosing the right oil for a diesel engine is crucial, and tools like the AMSOIL Lookup are invaluable in this process. This tool helps users select the right AMSOIL product for their specific vehicle and engine type, ensuring that the engine receives optimal protection and performance from the oil.

​

In conclusion, while diesel engines are known for their reliability and efficiency, they are not without their issues. The use of synthetic oil can play a significant role in mitigating common diesel engine problems. From protecting against glow plug failures, fuel system contamination, and oil oxidation, to reducing turbocharger problems, emissions, soot buildup, and corrosion, the benefits of using high-quality synthetic oil are clear. For engine mechanics, fleet mechanics, and motor mechanics, the choice of oil is a critical factor in maintaining the health and efficiency of diesel engines in fleet vehicles and beyond. With the right maintenance approach, including regular oil changes with the best synthetic engine oil like AMSOIL 15W40, many of the common problems associated with diesel engines can be significantly reduced, leading to better performance, longer engine life, and ultimately, cost savings.
