Can You Use Regular Oil After Synthetic?

Engine parts are lubricated with both regular and synthetic oil. Most individuals are unaware of the differences between conventional and synthetic oil, resulting in several misunderstandings. Everyone has an opinion on this matter, from vehicle professionals to well-known oil makers to ordinary people. People often ask if we can use conventional oil after synthetic oil.

So, can you use regular oil after synthetic? As a result, we decide to use logical reasoning to answer the question about synthetic and traditional oil.

What Is Synthetic Oil?

Before we get into the article’s main idea, let us give you a rundown of synthetic oil. Synthetic oil is a synthetic lubricant derived from artificial chemical compounds created by breaking and reconstructing petroleum molecules. It has now been used by nearly all autos, from passenger cars to high-performance cars and even airplanes. This oil is designed to replace petroleum-based lubricants when working in severe temperatures.

The other additives used in the oil and the synthesis method are determined by the manufacturer, resulting in differences between brands. Because of the inherently high viscosity index, they have fewer viscosity improver properties (VI). Synthetic oil with a high viscosity index (VI) can maintain its viscosity even when subjected to harsh temperatures. Synthetic oil is expensive, but it is superior in every way. This oil protects your engine better, and you won’t have to change it often.

Pros And Cons Of Synthetic Oil

Typically, the car’s oil needs to be changed every 5,000 to 8,000 kilometers. However, 100% synthetic oil vehicles will have to be changed every 10,000 to 15,000 kilometers. Synthetic oil has some advantages for car engines, as listed below:

  • Synthetic oil improves engine stability in a variety of temperature conditions. Even whether the weather and temperature are cold or hot, synthetic oil may maintain its original form without evaporating or thickening.
  • Regular oil degrades over time, forming sludge that reduces the engine’s efficiency and shortens its usable life. Synthetic oil extends engine life by protecting against ash and deposit formation, even sludge in the system, minimizing the risk of oil line blockage damage. 
  • Synthetic oil, on the other hand, is not prone to oxidative degradation. In contrast to the comparatively rapid degradation of mineral base lubricants, this oil retains long-term engine performance. Synthetic oil also has this advantage in terms of convenience and long-term stability for long voyages. 
  • When a vehicle travels at high speeds, engine components continually contact one another, causing friction. Because of the clash between the pieces, they are more prone to failure and wear and tear. Between the engine components, motor oils operate as a protective barrier. When compared to regular oil, synthetic oil keeps its damage prevention characteristics for a more extended period.

On the contrary, synthetic oil has some disadvantages, such as:

  • The most significant disadvantage of synthetic oil is its cost. Oil production is a far more complicated procedure. As a result, synthetic oil is roughly four times more expensive than petroleum-based oil. If you insist on changing the oil every 3,000 miles or feel comfortable doing so, this might be pricey. Experts recommend changing your oil every 3,000 miles, whether you use natural or synthetic oil. Although synthetic oil allows for fewer oil changes, it is not advised, especially for less-priced vehicles.
  • For brand new or newer automobiles, synthetic oil is not suggested. New automobiles require the friction caused by petroleum-based oils while they break in to operate effectively. If synthetic oil is utilized in a brand new car right away, the vehicle may not run as well as it should.
  • Synthetic motor oil is a serious pollutant in the environment. It contaminates water supplies, especially groundwater. When this happens, removing the oil from these sources becomes extremely difficult. Those who drink water from regions where synthetic oil has been deposited may have health problems. Though both petroleum-based and synthetic motor oils have the same environmental impact, synthetic motor oils appear to be discharged more frequently because many consumers believe synthetic oil is a cleaner alternative that will not affect the environment. 

What Is Regular Oil?

Regular oil, often known as conventional oil, is primarily used in older automobiles. It’s old engine oil made from crude oil that’s been naturally purified. Regular lubricants are now blended with base oils comprised of poly internal olefins (PIO), hydrocarbons, poly alpha olefins (PAO), pure hydrogen, and organic carbon molecules. Compared to synthetic oil, regular oil breaks down significantly more quickly. This oil contaminates the water, causing sludge and deposits to build, harming the engine components. Sludge obstructs the normal movement of engine parts, lowering engine performance and limiting its usable life. Reduced sludge on engine components also improves fuel economy. Conventional oil’s viscosity isn’t as consistent as synthetic oil’s. This oil is very temperature reactive, making it unsuitable for operations involving extremely low or extremely high temperatures. 

Pros And Cons Of Regular Oil

Traditional motor oil provides several technological advantages:

  • Conventional oil has a long track record as a lubricant and, when refined, yields essential gasoline products. When heat is applied to this fossil fuel (a mineral formed from compressed organic materials buried for ages underground), it becomes a potent energy source. As a result, standard oil is a convenient fuel for generating heat, combustion, and cooking.
  • Oil is relatively simple to manufacture. Once an oil field has been discovered, mining operations must dig down to reach the natural oil reservoir beneath. The oil then flows effortlessly out of the drilled escape because of the natural pressure it is under due to the earth’s weight. When the oil is under control, it can be pumped and packaged into millions of barrels for long-term transit. 
  • Because conventional oil has become such an essential resource for transportation and industrial production, a town or country’s lack of it poses a significant dilemma. Because the United States relies on foreign oil, it tries to safeguard such interests to keep oil flowing into the country going.
  • Both new and old cars will benefit from this product. During vehicle assembly, most manufacturers utilize standard oil. Regular oil is the best option for older vehicles, such as those built before 2000. People use synthetic oil in engines that have passed their prime, leaving conventional oil as the sole option.

However, conventional oil also has some disadvantages, as listed below:

  • It remains a hazardous liquid or sludge even after being used up. Oil can be recycled and reused in some circumstances after filtering. However, in many cases, such procedures are both costly and time-consuming. Oil can pollute the ground and underground water if improperly discharged. Eventually, highly polluted places will require expensive expert cleaning.
  • Conventional oil thins out when exposed to high temperatures. As a result, engine parts continue to rub together, causing wear and tear. This oil degrades when exposed to extremely high temperatures and provides little lubrication when utilized at low temperatures.

After Using Synthetic Oil, Can You Use Conventional Oil? 

After using synthetic oil, you can use regular oil. Because synthetic and conventional oil serves the same purpose, we can use traditional oil after synthetic oil. People have the impression that once they start using synthetic oil, they won’t be able to go back to conventional oil, which is a myth. Modern engines are designed to run on both traditional and synthetic oil. You can use regular oil for essential protection and function if you are ready to forego the more advanced benefits of synthetic oil.

The change from synthetic to standard oil may impact the vehicle’s performance. The only noticeable consequence is an increase in engine performance. In terms of quality, synthetic oil is far superior to standard oil. As a result, you’ll notice a shift in the engine’s steady performance. In fact, for people who only use their cars for commuting, standard oil is sufficient. Regular oil is also a superb option for anyone looking for low-cost engine oil that meets the minimum criteria. The oil is a better option than synthetic oil for older automobiles with high mileage and thinner and worn-out pistons.

When switching from synthetic to ordinary oil, it’s essential to consider your vehicle’s model. When it comes to changing oil types, newer automobiles have the advantage. When transferring from one oil type to another, older vehicles may experience some leaking issues. As a result, it’s critical to check with your vehicle’s manufacturer before performing an oil change.

Frequently Asked Questions (FAQs)

What Happens If Regular Oil Is Used Instead of Synthetic? 

Regular oil, rather than synthetic oil, may impact your engine’s performance. In contrast, synthetic oil improves the performance of your vehicle’s engine. Both of these oils contain identical additives. Regular oil also provides better protection for older cars, as they demand a moderate engine oil flow, as previously mentioned. As a result, regular oil can also serve the essential job of lubricating the engine well. However, regular oil does not provide adequate lubrication at high temperatures. It degrades quickly at higher temperatures, placing engine components at risk of wear and strain. It also degrades into sludge and deposits, lowering engine performance. It thickens at low temperatures and prevents the engine from starting quickly.

Similarly, during hot summers, it quickly overheats. Furthermore, new engines, such as turbocharged engines, may be harmed by the excessive deposit that forms owing to the poor fluidity of ordinary oil. Therefore, you must change your oil more frequently as the oil cannot withstand thermal degradation.

Can Synthetic Oil Be Used After Regular Oil?

Following the usage of conventional oil, you can use synthetic oil. First, ensure your engine seals are in good working order because if your present engine isn’t up to par, conventional oil may cause more harm than good. Always double-check the viscosity grade required for your vehicle and select a standard oil that meets the requirements. It is crucial to check with your car manufacturer to see if the synthetic oil corresponds with your engine. It’s a step up from standard oil to synthetic oil.

Can You Mix Synthetic Oil With Regular Oil?

Because synthetic and conventional oils are highly compatible, you can mix them. However, because the characteristics of their additives vary, you should conduct the process seldom and for a short time, or else the overall engine performance may suffer. The viscosity of both oils should be comparable. Furthermore, whether or not this mixture will harm your engine is dependent on how often you do it. In an emergency, blending a portion of traditional oil with synthetic oil and vice versa is probably not a bad idea. However, regular blending may cause your engine to malfunction. The reason is that synthetic oil has fewer impurities and advanced detergents than conventional oil, even though both include similar base oil and additives. As a result, frequent mixing of low-grade and premium oil can cause the engine to malfunction. Instead of mixing synthetic and conventional oils, you should buy a high-quality synthetic blended oil. Because professionals make these blended oils, you won’t have to worry about harm from poor viscosity and quality.

Conclusion

This article answers the question: can you use regular oil after synthetic? to the consumers. Synthetic oil is superior to traditional oil for various reasons, including low viscosity, excellent lubrication, and a longer lifespan, to name a few. The oil is appropriate for high-performance engines, towing and heavy weights, luxury car engines, and driving. Nevertheless, you also cannot skip the advantages of using regular oil. You can do it if you still want to go from synthetic to natural. Following the switch, you will notice a drop in engine performance. Whatever oil you choose, make sure to change it regularly.
