It is better to start off this article by comparing synthetic against the conventional oil, of which the latter is far better when it comes to its longevity and its ability in handling extreme temperatures without the tendencies of breaking down. While such technological advances do not come very cheap over the conventional oil, the best synthetic oil is worthy as it goes beyond better performance characteristics.
Surely, there are several factors to consider, but many experts would highly recommend the synthetic type of oil nowadays because for now, it is the lesser between the two evils. Conventional oil is derived from petroleum, while synthetic is derived from chemicals, which are less harmful to the environment, and can last for three times longer compared to its counterpart. Thus, dumping of quarts of oil in a yearly manner is reduced.

Basic Components and Benefits
Primarily, the synthetic type is refined, distilled, and purified that has been broken down into the basic molecules. Such process resulted in the eradication of impurities from the crude oil, while enabling the molecules to be customized for the modern engines’ demands. The tailored molecules tend to offer higher levels of performance and protection than the conventional oil. Throughout the process, blend additives are mixed with the synthetic base oil, creating the correct and powerful synthetic oil.
In this regard, having the best synthetic engine oil will help you in different ways such as:
- Keeping the Engine Cleaner – The oil tends to pick up deposits as it circulates through the engine. Conventional oil can form sludge, reducing the engine’s efficiency, including the engine life. But, with synthetic oil that contains fewer impurities, there is a better chance of resisting sludge formation; thereby, preventing deposit formation and leads to a cleaner engine.
- Resulting in Better Engine Wear Protection – While engine parts continually come in contact with one another, it is also crucial to have something that promotes engine wear protection, especially at high speeds. Thus, the motor oil serves as the protective barrier throughout the frictional motions of your engine parts. Synthetic oil comes into the picture as it retains the wear protection properties of your engine parts in a longer time than conventional oil, thus, increasing the engine life as well.
- Improving Flow in Low Temperature – Whether it’s just overnight or during cold winter months, synthetic oil tends to make the flow process better once you fire up the ignition, protecting the engine parts against friction, while promoting a smooth flow through the engine. Synthetic oils tend to flow quickly, despite low temperatures, starting the engine protection immediately as you fire up the engine.
- Enhancing Protection at High Temperatures – Engines become hot as they are running, and this state may cause engine wear. However, the synthetic engine oils resist such high temps, which is a crucial property during hot climates.
- Protecting Crucial Turbocharger Parts – Turbocharged engines are rampant nowadays as car manufacturers would like to create small engine-cars that also lead to better fuel efficiency. Turbocharged engines, however, are more aggressive in nature, thus it needs synthetic oil that will lubricate the shaft properly and quickly, protecting the crucial components, while running at its optimal performance.
Types of Motor/Engine Oil
Apart from the basic components and benefits of synthetic oil, it is equally essential to understand the common types of engine or motor oil. The following information will give you a complete idea on the existing products on the market, while comparing the synthetic motor oil reviews provided by other articles as well.
Premium Conventional Motor Oil – This is considered as the standard oil for new cars as all top brands offer one for the service level. It is also available in different viscosities. There are three ratings, covering this type of oil, including 5W-20, 5W-30, and 10W-30 for low temperatures and high ambient temperatures respectively. Such ratings also cover every light-duty car on the road and require regular oil and filter change such as 4,000-mile or 4-month interval as a good practice.
Full Synthetic Oil – This type of oil is engineered for high-tech engines as these products go through stringent special tests that are indicated by their labels. It offers superior and longer-lasting performance than the conventional oil, especially in critical areas. It has deposit protection property with better flow at low temperatures, while retaining optimal lubricity at high temps. This oil type is more expensive than the conventional counterpart, although it offers unmatched benefits.
Synthetic Blend Oil – A synthetic oil review also indicates the existence of synthetic blend oil, which is combined with organic oil. Its overall formulation is to provide protection against high temperatures and heavier loads. It is less volatile, hence, evaporating less and reducing oil loss. This oil type is less expensive than the full synthetic, but more expensive than the conventional type.
High Mileage Oil – The higher mileage oil is another choice when it comes to engine or motor oils. However, this oil type is engineered for higher-mileage automobiles. Oil refiners also identified this oil type as a major customer interest, and recommend such for high-mileage vehicles.
Answering the question on who makes the best synthetic oil is already delivered in this review. There is no need to look further as the best and most efficient synthetic oil for your car has been made available on the market with reasonable price tags. The only thing you need to assess is the oil’s viscosity, which is the resistance to flow. Keep in mind that higher viscosity results in a slower flow, while lower viscosity equates to faster oil flow.
There is also a difference between the single-grade and he multi-viscosity oils, wherein single-grade oil is suitable for vintage or classic cars without using a polymeric Viscosity Modifier. The multi-viscosity oil, on the other hand, has been formulated to compensate engine wear, which is caused by extreme temperature.
All in all, full synthetic engine oil is generally used in high-performance applications and with engines with tight tolerances, high compression applications like turbocharged or supercharged motors, and high engine temperature. The best synthetic motor oil addresses these issues, ensuring and maintaining cleaner and more efficient engine all the time.
