Understanding the Basics of Diesel Engine Oil
Diesel engine oil is a specially formulated lubricant designed to work with the unique mechanics of diesel engines. Its primary role is to create a thin, slippery layer between metal surfaces in your engine, reducing friction, minimizing wear and tear, and promoting smoother operations.
Diesel engine oils contain various additives that enhance their performance to contend with the high compression ratios and massive amounts of combustion byproducts associated with diesel engines.
Choosing the right diesel engine oil is crucial for your engine’s performance and lifespan. It’s responsible for enabling your engine to operate efficiently, extending its life, and safeguarding against damage. The type of engine oil you use directly influences the engine’s performance, gas mileage, and emissions output. Failing to select the appropriate oil not only compromises these aspects but can also have severe consequences, including costly repairs or even complete engine failure.
Heavy Duty Diesel Engine Oil
Heavy duty diesel engine oils are specifically created lubricants for commercial transport, agriculture, or mining equipment and vehicles fueled by diesel. AQAP Oil Refinery, one of the top-heavy diesel engine oil manufacturers around the world, offers a broad assortment of heavy-duty diesel engine oils. AQAP range of heavy-duty diesel engine oils are suitable for light, medium, and heavy commercial vehicles, and also new low emission engines with ULSD.
Heavy Duty Diesel Engine Oil Uses
AQAP heavy duty diesel engine oils are suitable for both on and off-highway diesel engines, naturally aspirated and turbocharged 4-stroke diesel engines, and construction equipment. Applications of AQAP’s heavy duty diesel motor oils include:
AQAP SP4 20w50 is ideal for constant high speed engines and stop-start applications operating under severe conditions.
It offers excellent protection against corrosion.
It provides good thermal and oxidation stability with superior detergent and dispersant qualities to control high amounts of deposits and soot. All these benefits add up to enhanced equipment life and reduced maintenance costs.
AQAP SPD30 is ideal for turbo charged, inter-cooled engines, non-vehicular equipment like pumps which operate under steady state conditions, and various construction equipment as well.
It provides excellent lubrication under severe service conditions.
It also provides complete protection against corrosion, piston deposits and soot, thus maintaining a clean engine and enhancing its life.
Understanding Diesel Engine Oil Types
Diesel engines require oils that can handle high temperatures and pressures. The main types of diesel engine oils include:
Full Synthetic Oil: Offers superior performance in extreme temperatures, both hot and cold. It provides better lubrication, fuel efficiency, and longevity. Synthetic oils are particularly beneficial for modern diesel engines with advanced technology. Learn more about Synthetic vs. Conventional Oil.
Synthetic Blend Oil: A mix of synthetic and conventional oils. It offers some benefits of full synthetics but at a lower cost. Suitable for moderate driving conditions.
Conventional Oil: Best for older diesel engines or those with simple engine designs. It’s less expensive but doesn’t offer the same level of protection as synthetic oils.
High-Mileage Oil: Specifically formulated for diesel engines with over 75,000 miles. These oils contain additives to protect ageing engine seals and reduce oil consumption. Discover more about High Mileage Vehicle Oil Changes.
