All About Motor Oil

How is motor oil made?

The production of motor oil involves the meticulous blending a range of essential additives with base oils, which serve as the primary foundation of the formula. These additives are carefully selected to enhance the oil’s performance and longevity. Among them, you’ll find anti-wear additives that safeguard your engine components, detergents, dispersants designed to maintain cleanliness by preventing the buildup of deposits, and viscosity index improvers that ensure the oil maintains its optimal consistency across various temperature ranges. Through a precisely controlled process, these base oils and additives are combined to create high-quality motor oil that plays a vital role in protecting and optimizing the performance of your engine.

What are the different types of motor oil?

Full Synthetic Motor Oil

This premium-grade engine oil stands out for its exceptional purity and performance attributes. It is meticulously engineered with minimal impurities, which makes it highly effective in resisting the formation of sludge and deposits in your engine. What sets full synthetic motor oil apart is its remarkable stability and viscosity across a wide range of temperatures, delivering superior performance in both high-heat and low-temperature conditions. This stability and resistance to viscosity breakdown surpass the capabilities of conventional oils or even synthetic blends, making full synthetic motor oil a top choice for those seeking optimal engine protection and efficiency.

Synthetic Blend Motor Oil

This versatile and popular choice serves a range of vital functions to optimize your engine’s performance. This blend of synthetic and conventional oils excels at safeguarding engine components from water damage by forming a protective barrier. It offers enhanced protection, particularly in extreme high-temperature conditions, and effectively prevents oil leaks, ensuring that your engine remains leak-free and efficient. Moreover, synthetic blend motor oil provides superior protection against friction and engine wear, extending the lifespan of critical components. Its unique formulation also works to reduce sludge formation, effectively keeping the engine clean and free from harmful deposits, thus promoting a more efficient and long-lasting engine operation.

Conventional Motor Oil

This traditional and time-tested lubricant possesses characteristics that make it particularly well-suited for certain applications. It is worth noting that over time, conventional oils may develop sludge, which can potentially diminish engine efficiency and longevity. However, for older vehicles, conventional motor oil proves advantageous due to its higher viscosity compared to synthetic oils. This thicker consistency provides enhanced lubrication, reducing the risk of grinding gears and mitigating engine wear by facilitating a more deliberate flow. As a result, conventional motor oil is often preferred for older cars where the slower, steadier flow of oil proves beneficial in maintaining engine performance and minimizing potential issues.

High-Mileage Motor Oil

This formula is specifically formulated to cater to the unique needs of older engines that have accumulated significant mileage over their lifetime. The specialized oil contains a tailored blend of additives – including conditioners, seal swells, antioxidants, detergents, and friction-reducing agents – all of which work in tandem to address the particular challenges faced by older engines. These engines often require an oil that maintains a thicker consistency for an extended period to effectively protect engine components, especially in areas where wear and tear are more likely to occur. High-mileage motor oil is a dependable choice for those looking to maintain and extend the life of their well-worn engines, providing the extra care and protection necessary to keep them running smoothly.

What are the basic steps of an oil change?

  1. Your mechanic will ensure that the vehicle is securely parked in the ‘Park’ gear, activate the emergency brake, and employ safety measures like wheel blocks to prevent any inadvertent movement. This ensures a stable working environment for your efficient, drive-thru oil change.
  2. Our San Diego motor oil change professionals will carefully position the vehicle over the service area and proceed beneath it to locate the vital oil drain plug, which acts as the gateway to the engine oil. A designated oil collection pan is strategically placed beneath this point to facilitate the orderly drainage of used oil.
  3. As the old oil flows into the collection pan, your skilled mechanic will attend to the replacement of the oil filter. The filter change is a pivotal step in maintaining the engine’s optimal functionality. Experienced technicians like those at Coronado Shell often advise the periodic replacement of the oil drain plug gasket, which not only preserves an effective seal but also contributes to the smooth operation of the engine, thus ensuring its longevity and health.
  4. We’ll use fresh oil to lubricate the rubber gasket on the new oil filter, then hand-tighten the new filter onto the engine. To replace engine oil, we use a funnel to pour the recommended amount and type of fresh oil into the engine via the cap at the top of the engine.
  5. Your mechanic will start the engine and let it run for a minute. Then we’ll turn it off, wait a few minutes, and then check the oil level using the dipstick. If we find that more oil is needed, we’ll add more until it reaches the optimal level.
  6. We’ll take care of tasks like safely disposing of the used oil, recording the date and mileage of your oil change for future reference, and disposing of used filters in an environmentally responsible manner while you head off on your next adventure.

What is oil viscosity?

Oil viscosity is a crucial property that signifies the thickness or consistency of an oil, particularly at different operating temperatures. The numeric value to the right of the “W” on the oil label indicates its viscosity under normal operating conditions. It’s essential to recognize that the “W” stands for Winter, signifying the oil’s viscosity when the engine is cold. A higher number in this context signifies a thicker oil consistency, which equates to superior protection for the engine, especially in high-heat environments. This rating helps vehicle owners select the right oil to ensure optimal lubrication and protection for their engines, whether in cold winter starts or during high-temperature conditions.

Fun Facts About Motor Oil

  • A widespread misconception is that engine oil should be changed solely based on a darkening color. In reality, oil’s transformation in color is primarily due to the dispersion of minute particles and does not necessarily signal the need for an oil change. Instead of evaluating the color of your oil, follow the maintenance schedule in your owner’s manual, which will likely recommend oil changes every 3 to 6 months or every 3,000 to 5,000 miles.
  • Synthetic engine oil is renowned for its ability to safeguard your vehicle against the harshest conditions. However, it’s important to note that while synthetic oil offers superior protection, it doesn’t necessarily translate to an immediate increase in performance or fuel efficiency.
  • Engine oil plays a vital role in the operation of internal combustion engines. Its primary functions include reducing friction and wear on moving components, and it also serves as an effective lubricant and cleaner, preventing the formation of engine-degrading sludge.
  • Engine oil can be recycled and re-processed, contributing to environmental sustainability by reducing waste and the need for new oil production.
  • Different types of engines, such as diesel and gasoline engines, often require specific formulations of motor oil tailored to their unique requirements, highlighting the importance of selecting the right oil for your vehicle.

Why are routine oil changes so important?

Regular oil changes are of paramount importance when it comes to maintaining the health and longevity of your vehicle’s engine.
