The viscosity of engine oil does not change significantly with age. However, the additive package that keeps the oil fresh can degrade over time, leading to a loss of performance.
As motor oil ages, it breaks down and becomes less effective at lubricating your engine. This can cause increased wear on engine parts, leading to premature failure. The thicker an oil is, the greater its resistance to flow.
This means that as an oil ages, its viscosity (thickness) increases. However, this increase is small and isn’t generally a cause for concern.
What Happens to Engine Oil As It Gets Older?
As motor oil ages, it breaks down and loses many of its properties. The rate at which this happens depends on several factors, including the type of oil, the additives used, the method of refining, and the storage conditions. One of the most important properties of motor oil is its ability to lubricate engine parts.
As motor oil ages, it becomes less effective at lubricating moving parts. This can lead to increased wear on engine components and ultimately result in engine failure. Another property of motor oil is its ability to clean engine parts.
Over time, dirt and debris accumulate in the oil, reducing its effectiveness in cleaning the engine. This can lead to a build-up of deposits on engine components, which can eventually cause engine damage. In addition to these two main properties, motor oil also has other important functions, such as cooling and sealing.
As motor oil ages, it loses its ability to perform these functions as well.
Should I Get Thicker Oil in an Older Engine?
As engines age, they can start to burn oil. This is especially true for high-performance engines that operate at temperatures higher than average. If your engine is starting to burn oil, you may wonder if switching to a thicker oil is a good idea.
The answer isn’t always cut and dry, but in general, it’s a good idea to use a thicker oil in an older engine. The main reason for this is that thicker oils provide more protection against wear and tear. As engines age, they can start to develop cracks and leaks, and the seals and gaskets can deteriorate.
Thicker oils can help prevent these problems by providing a better seal between the engine parts. Of course, there are downsides to using thicker oils as well. One is that they can make your engine run less efficiently because they don’t flow as easily as thinner oils.
This means that your engine has to work harder to pump the oil around, which can lead to increased fuel consumption. Another downside is that thick oils can make it difficult for your engine to start on cold mornings. So, should you switch to a thicker oil in an older engine?
It depends on the individual situation, but in general, it’s a good idea.
Does Engine Oil Thicken or Thin When Hot?
As the engine heats up, the oil starts to break down and gets thinner. This is why it’s essential to check your oil level regularly and top it up as needed. When the engine is cold, the oil is thicker and provides better protection for the engine components.
As the engine heats up, the oil breaks down and becomes less effective at lubricating and cooling the engine.
Does Engine Oil Get Thinner?
Yes, engine oil does get thinner over time. This is because it breaks down and loses its viscosity. Viscosity is a measure of an oil’s ability to flow.
As oil breaks down, it becomes less able to flow, which can lead to engine problems. To prevent this, it’s important to change your oil regularly.
Thicker Oil For Older Engines? Myth Busted!
What Causes the Viscosity of Oil to Increase
The viscosity of oil is determined by its molecular weight, and the heavier the molecules in the oil, the higher its viscosity. The primary reason motor oils become thicker with age is the gradual breakdown of their additives. These additives help prevent them from clumping together, but over time, they break down and can no longer perform this function effectively.
This causes the oil to become thicker and less able to flow freely through your engine, which can lead to decreased fuel economy and increased wear on engine parts.
Best Engine Oil
The best engine oil for your car is one that meets the specifications set by the manufacturer. The type of oil may be different for each make and model of vehicle. Refer to your owner’s manual to determine the recommended type of oil for your vehicle.
It is also important to use the correct viscosity, or thickness, of oil in your engine. Refer to your owner’s manual or the placard on the inside of your car door to determine the correct viscosity for your vehicle. If you are unsure about which type or viscosity of oil to use in your car, consult a qualified mechanic or visit a reputable service station.
Many service stations will have personnel who can assist you in selecting the right oil for your car.
Sae Oil Meaning
Sae OiMeaningng The Society of Automotive Engineers (SAE) sets standards for motor oil viscosity grades. The higher the number, the thicker the oil.
For example, SAE 5W-30 motor oil is thinner than SAE 10W-30 motor oil when cold and thicker when hot. The “W” in both designations stands for winter. The first number after the W indicates how well the oil flows at low temperatures.
The lower the number, the easier it is for your engine to turn over on a cold morning. The second number after the W indicates high-temperature viscosity. That’s important because as engines run, they create heat and friction that can break down conventional motor oils.
A higher number means better protection against breakdowns at high temperatures.
Motor Oil Brands to Avoid
If you’re looking for the best motor oil for your car, you might be tempted to choose a well-known brand. However, not all motor oils are created equal. Some brands use lower-quality ingredients or cut corners in their production process, which can lead to subpar performance and potential engine damage.
To help you make an informed decision, we’ve compiled a list of motor oil brands to avoid. These brands have received poor reviews from customers and experts alike, so it’s best to steer clear. Valvoline: Valvoline is one of the most popular motor oil brands on the market, but it doesn’t always live up to its reputation.
In recent years, the company has been accused of using lower-quality ingredients in its products and cutting corners in its production process. As a result, some customers have complained of subpar performance and engine damage after using Valvoline motor oil. Castrol: Castrol is another well-known brand that has come under fire in recent years.
Like Valvoline, the company has been accused of using lower-quality ingredients and skimping on quality control. This has led to complaints of poor performance and engine damage from customers who have used Castrol motor oil. Shell: Shell is a major player in the motor oil industry, but it hasn’t always been known for producing high-quality products.
In fact, the company was fined $2 million by the Federal Trade Commission in 2015 for false advertising claims about its “PurePlus” technology. While Shell has made improvements since then, some customers continue to report issues with its products, including premature wear and tear on engine parts.
Conclusion
As motor oil ages, it breaks down and becomes less effective at lubricating and cooling your engine. Over time, it can also become thicker, making it harder for your engine to start on cold mornings. If you’re unsure whether your oil is still good, you can check the thickness with a simple test.
