what is engine oil​?


Engine oil is the lifeblood of your vehicle, working tirelessly behind the scenes. It circulates inside the engine, performing key functions such as lubrication, cleaning, cooling, sealing, and rust prevention.while you focus on the road, it ensures that your engine runs smoothly and reliably. Engine oil is more than just a fluid to be changed; it's your first line of defense and an unsung hero that protects your investment and enhances your driving experience. Understanding its vital role is important not just for mechanics but for every driver who values performance, longevity, and peace of mind.



Why is engine oil so important to a vehicle?


During engine operation, components such as the crankshaft, pistons, camshafts, and valvetrain move back and forth or rotate at high speeds. If these metal parts were to come into direct contact, it would create intense friction and cause severe wear. However, engine oil creates a continuous and stable film on the surfaces of these components, effectively preventing metal-to-metal contact. This significantly reduces friction, prevents component wear, and ensures smooth and efficient engine performance.


The engine produces a considerable amount of heat during combustion. While the coolant helps remove some of this heat through its channels, the oil circulating within the engine also absorbs heat from high-temperature areas. This process prevents components from overheating and helps maintain a stable engine temperature.


During fuel combustion, various impurities are produced, including carbon particles, oxides, unburned fuel, and metal shavings. Detergents added to engine oil help disperse and suspend these contaminants, preventing them from sticking to component surfaces and forming sludge or carbon deposits. The oil filter then removes these contaminants, ensuring the engine remains clean and reliable.


In an engine, there are tiny gaps between the piston rings and the cylinder walls, as well as between the valve guides and valve stems. Oil creates a sealing film in these areas, which helps prevent combustion gases from escaping. This oil film functions like an airtight gasket, effectively preventing blow-by, ensuring a proper seal in the combustion chamber, and maintaining stable engine power output.


The high temperature and humidity inside the engine, along with the presence of acidic combustion products, make metal parts highly susceptible to oxidation and corrosion. The rust inhibitors and antioxidants found in engine oil work to create a protective layer on the metal surfaces. This layer helps to inhibit oxidation and prevent rust, ensuring that the engine can start smoothly even after extended periods of use or storage.

What are the types of engine oil? What is the difference between them?


Mineral engine oil: It is taken directly from petroleum and then refined using basic physical distillation and solvents. Suitable for older naturally aspirated engines that use less oil or low-load agricultural machinery.


Part-Synthetic Engine Oil: Base oil molecules are created artificially using complicated chemical synthesis techniques (such as olefin polymerization and ester synthesis). They are appropriate for some turbocharged engines, high-performance sports cars, vehicles regularly used in extreme weather (extreme cold or heat), and vehicles with long oil change intervals.


Fully-synthetic engine oil: Based on mineral oil, a considerable proportion (usually about 30%) of fully synthetic oil and additives are added. The most popular pick. Suitable for most normally aspirated everyday commuter vehicles. It is the optimal solution for balancing cost and performance.



How to check engine oil?

  1. Preparation: Position the car on a flat surface, deactivate the engine, and allow it to remain stationary for 5-10 minutes to ensure the oil in all components returns to the oil pan for an accurate measurement.
  2. Identifying the Oil Dipstick: Access the engine compartment and identify the dipstick handle, typically a conspicuous yellow or orange pull ring marked with an oil droplet or engine symbol. It is located inside the guide tube on the side of the engine.
  3. The Dipstick's cleaning: Remove the dipstick slowly. The end of the dipstick that was saturated in oil should be thoroughly cleaned with a soft cloth or lint-free tissue to remove any remaining oil stains.

  4. Secondary Measurement: Fully insert the cleaned oil dipstick into the original guide tube until it snaps into place. Slowly remove it again. The oil mark on the dipstick indicates the current oil level.

  5. Reading the Oil Level
    Observe the markings on the end of the dipstick:

    Upper limit mark: Often marked "MAX" or "F"

    Lower limit mark: Often marked "MIN" or "L"

The optimal oil level should be between the upper and lower thresholds, ideally nearer to the upper threshold. If the level approaches or falls below the lower limit, promptly add oil of the identical specification. Should the level exceed the upper limit, remove any surplus oil to prevent heightened operational resistance or oil seal failure.

What is the best engine oil?


There is no single "best" oil for your car, only the "most suitable" oil. You can understand it as the "prescription drug" of the engine, not the "health product". The best "medicine" is the one that best suits the "condition" and "constitution" of your vehicle.


Biaobang engine Oil is a globally recognised brand known for its dependable and economical engine oil. Biaobang Engine Oil offers a diverse product range, encompassing mineral oil to entirely synthetic oil, catering to various vehicles and budgets while delivering adequate engine protection at a competitive price.



How often to change engine oil​?


The Golden Rule: Trust Your Owner's Manual


This is the essential advice to ensure the longevity and reliability of your vehicle while preserving its warranty. Automakers invest significant time and resources into rigorous bench and road testing during the development of their vehicles. Their recommendations are tailored specifically to meet the design and performance requirements of your engine. Your owner's manual unequivocally states, "Under normal driving conditions, it is recommended that the engine oil be changed every XX kilometers or XX months." This guidance is not just a suggestion; it is your most reliable roadmap for maintaining your vehicle optimally. Always prioritize it in your maintenance routine. Following these recommendations will help you maintain peak performance and protect your investment.


The oil change indicator or maintenance reminder light


It typically lights up for a few seconds upon ignition, conducting a self-test to ensure everything is functioning properly. However, if this light activates while you're driving, it serves as a crucial reminder that it's time for an oil change. Don't overlook this important signal—keeping up with your oil changes is vital for your engine's health and your vehicle's overall performance.


Oil life monitoring system


This advanced system transcends basic mileage calculations. It meticulously analyzes critical factors such as engine speed, temperature, operating hours, and load to deliver a thorough evaluation of actual oil loss. When the oil percentage falls to 0% or approaches 5%, the maintenance light activates, ensuring you never miss a timely oil change. Experience the most sophisticated and tailored oil change reminder on the market, designed to enhance your vehicle’s performance and longevity.


The most effective approach is a strategic blend of user manual recommendations, system prompts, and consistent self-inspection. This powerful combination ensures not only reliability but also optimal performance in your operations.



What engine oil does my car take​-All in all


Choosing the right engine oil is like giving the engine the right nutrition; changing it regularly is like giving it a new cycle. Only by taking both into account can you unleash strong vitality and ensure a long life.
