What is Synthetic Oil?
Synthetic oil, also known as synthetic lubricant, is a type of oil that is manufactured through chemical reactions, rather than being refined from crude oil like conventional oil. This process allows synthetic oil to be designed with specific properties and characteristics that make it superior to conventional oil in many ways.
Composition of Synthetic Oil
Synthetic oil is typically made from a combination of base oils and additives. The base oils are usually hydrocarbons, such as polyalphaolefins (PAO) or polyalkylene glycols (PAG), which provide the oil’s lubricating properties. Additives, such as detergents, dispersants, and anti-wear agents, are added to the base oils to enhance the oil’s performance and protect the engine.

Characteristics of Synthetic Oil
Synthetic oil has several characteristics that make it superior to conventional oil. Some of the key characteristics include:
- High viscosity index: Synthetic oil has a high viscosity index, which means it remains stable and maintains its lubricating properties over a wide range of temperatures.
- High thermal stability: Synthetic oil has a high thermal stability, which means it can withstand high temperatures without breaking down or degrading.
- Low volatility: Synthetic oil has a low volatility, which means it evaporates slowly and doesn’t leave behind a residue.
- High lubricity: Synthetic oil has a high lubricity, which means it provides excellent lubrication and reduces friction between moving parts.
What Does Synthetic Oil Look Like?
So, what does synthetic oil look like? Synthetic oil is typically clear or slightly yellowish in color, depending on the type of base oil used. It has a characteristic viscosity and density, which can be measured using specialized equipment. (See Also: Why Would My Engine Be Burning Oil? – Unveiled)
Density of Synthetic Oil
The density of synthetic oil is typically measured in units of mass per unit volume, such as grams per milliliter (g/mL). The density of synthetic oil can range from 0.8 to 1.0 g/mL, depending on the type of base oil used.
| Type of Base Oil | Density (g/mL) |
|---|---|
| PAO | 0.85-0.95 |
| PAG | 0.9-1.0 |
Viscosity of Synthetic Oil
The viscosity of synthetic oil is typically measured in units of centistokes (cSt) or millipascal-seconds (mPa·s). The viscosity of synthetic oil can range from 2 to 10 cSt or 2 to 10 mPa·s, depending on the type of base oil used and the intended application.
| Type of Base Oil | Viscosity (cSt) |
|---|---|
| PAO | 2-6 |
| PAG | 4-10 |
Differences Between Synthetic Oil and Conventional Oil
Synthetic oil and conventional oil have several differences in terms of their composition, characteristics, and performance. Some of the key differences include:
- Base oils: Synthetic oil is made from a combination of base oils and additives, while conventional oil is refined from crude oil.
- Viscosity index: Synthetic oil has a higher viscosity index than conventional oil, which means it remains stable over a wider range of temperatures.
- Thermal stability: Synthetic oil has a higher thermal stability than conventional oil, which means it can withstand higher temperatures without breaking down.
- Lubricity: Synthetic oil has a higher lubricity than conventional oil, which means it provides better lubrication and reduces friction between moving parts.
Advantages and Disadvantages of Synthetic Oil
Synthetic oil has several advantages and disadvantages that should be considered when deciding whether to use it in your vehicle.
Advantages of Synthetic Oil
- Improved fuel efficiency: Synthetic oil can improve fuel efficiency by reducing friction between moving parts and allowing the engine to run more smoothly.
- Extended engine life: Synthetic oil can extend engine life by protecting the engine from wear and tear and reducing the risk of corrosion.
- Better performance in extreme temperatures: Synthetic oil can provide better performance in extreme temperatures, such as very hot or very cold temperatures.
- Improved lubrication: Synthetic oil can provide better lubrication, which can reduce friction and wear on moving parts.
Disadvantages of Synthetic Oil
- Higher cost: Synthetic oil is typically more expensive than conventional oil.
- Not necessary for all vehicles: Synthetic oil may not be necessary for all vehicles, depending on the type of engine and the driving conditions.
- May not be compatible with all engines: Synthetic oil may not be compatible with all engines, so it’s important to check the manufacturer’s recommendations before using it.
- May require more frequent changes: Synthetic oil may require more frequent changes than conventional oil, depending on the type of oil and the driving conditions.

FAQs
What is the difference between synthetic oil and conventional oil?
Synthetic oil is made from a combination of base oils and additives, while conventional oil is refined from crude oil. Synthetic oil has a higher viscosity index and thermal stability than conventional oil, and it provides better lubrication and reduces friction between moving parts.
Is synthetic oil necessary for all vehicles?
No, synthetic oil may not be necessary for all vehicles. It’s important to check the manufacturer’s recommendations before using synthetic oil in your vehicle.
Can I use synthetic oil in my conventional oil engine?
No, synthetic oil may not be compatible with all engines. It’s important to check the manufacturer’s recommendations before using synthetic oil in your vehicle.
How often should I change my synthetic oil?
The frequency of changing synthetic oil depends on the type of oil and the driving conditions. It’s generally recommended to change synthetic oil every 5,000 to 7,500 miles, but it’s best to check the manufacturer’s recommendations. (See Also: Should You Change Oil When Engine Is Hot or Cold?

Is synthetic oil worth the extra cost?
Whether or not synthetic oil is worth the extra cost depends on your specific needs and driving habits. If you drive in extreme temperatures, tow a trailer, or drive in stop-and-go traffic, synthetic oil may be worth the extra cost. However, if you drive in normal conditions and don’t need the extra protection, conventional oil may be sufficient.
