The automotive industry is characterized by diverse innovations that have evolved over the years. Just like automobiles have upgraded from one decade to another, their parts and accessories have followed the trend.
Synthetic oil vs. conventional oil is an argument that has emanated from the automotive industry’s evolution. While some car owners believe there’s no need to switch from using regular oil, others have testified about their experience with using synthetic oil.
This article explores the nitty-gritty of conventional oil and synthetic oil, especially the area of their advantages, disadvantages, as well as their differences.
Synthetic Oil vs. Conventional Oil Explained
Synthetic oil is a distinct lubricant manufactured with artificial chemical compounds that are a product of breaking down and rebuilding petroleum molecules.
This fluid is a special type of lubricant specifically derived from petroleum components that are chemically modified rather than direct crude oil. Synthetic oil is unique due to the virtually similar size and structure of the molecules in the content.
Synthetic oil is also synthesized from other raw materials; however, crude oil remains the base material. Although being the base material, the crude oil content is subjected to physical and chemical modifications.
The synthesis process and combination of various additives are the major trade secret of different synthetic oil producers like Mobil 1, Valvoline, or Castrol. Other great brands include Pennzoil platinum and ultra platinum.
Conversely, conventional oil is manufactured with whole refined crude oil. The sizes, shapes, and structures of the molecules in regular motor oil differ. This is a major drawback of conventional motor oil.
Synthetic oil can either be a full synthetic or synthetic blend. The fully synthetic engine oil is virtually synthetic based and it’s designed molecule after molecule with no petroleum. It also includes additives that aid the degradation of the fluid.
On the other hand, a synthetic blend consists of a synthetic stock base and regular motor oil. This mixture provides better protection and improved performance than just using conventional motor oil. You may want to take out time to find out more about synthetic oil vs. synthetic blend.
Synthetic Oil vs. Conventional Oil Viscosity
Synthetic oil features a better viscosity and stability compared to conventional oil. It flows quickly during winter and resists high temperatures, sustaining the fluidity of the oil under any condition.
The viscosity grade of synthetic oil is 0W-30. However, some synthetic oil also features a viscosity grade of 5W-30, especially for warm weather.
Conversely, conventional motor oil features a relatively poor viscosity and stability, resulting in fluid thickness during cold temperatures. This automatically hinders the quick flow of the oil.
The viscosity grade of a conventional oil is 5W-30. This viscosity grade is only compatible with warm weather. Many older vehicles use 5W-30 synthetic oil.
Synthetic Oil vs. Conventional Oil Grade
Synthetic oil comes in different grades, including 5W-20, 10-W-30, 5W-30, and 15W-50. These various grades of synthetic oil are suitable for different weather conditions. For example, while 5W-20 is meant to perform well under colder temperatures, 5W-30 is designed for warm temperatures.
On the contrary, conventional oil only has a 5W-40 viscosity grade, making it more suitable for hot temperatures rather than cold temperatures.
Synthetic Oil vs. Conventional Oil Performance
Vehicle performance can be enhanced or hindered by the type of oil you use. Synthetic oil performs better than conventional motor oil. It protects a vehicle’s engine due to less friction.
Synthetic oil also contains additives that help to clean harmful deposits from contaminating the engine. The fewer impurities make the oil burn cleaner and prevent the fluid from becoming thick under colder temperatures.
Meanwhile, conventional oil is more suitable for older vehicles due to its high viscosity. It offers better lubrication, reduced chance of gear grinding, and vehicle engine wear due to the flow of the fluid.
However, synthetic oil outshines conventional motor oil when it has to do with general performance and its compatibility with both cold and hot temperatures.
Synthetic Oil vs. Conventional Oil Fuel Economy
The fuel economy is a major concern for most car owners. However, the type of oil in your car can either affect the fuel economy positively or negatively. The properties of synthetic oil automatically impact a vehicle’s fuel economy positively.
For example, the quick flow, fewer deposits, and low viscosity make a vehicle’s engine perform better, resulting in less fuel consumption.
Meanwhile, the properties of conventional motor oil hinder good fuel economy. The high viscosity that results in fluid thickness under cold temperatures negatively impacts a vehicle’s engine performance, thereby resulting in poor fuel economy.
Synthetic Oil vs. Conventional Oil Price
If you’re contemplating conventional oil vs. synthetic oil price, no doubt, synthetic oil is relatively more expensive than regular motor oil.
The average cost of changing a vehicle’s conventional oil is around $38, while the cost of changing synthetic oil is about $78. This is almost twice the amount of regular motor oil.
However, changing conventional oil as a DIYer costs around $28 for 5 quarts, while synthetic oil costs $45. Irrespective of the low price of conventional oil, synthetic oil is still a better choice, especially if you can afford it.
