Types of Engine Oils
Engine oils are classified based on their viscosity, which is a measure of their thickness and flowability. Viscosity is measured in centistokes (cSt) or Saybolt Universal Seconds (SUS). The most common types of engine oils are:
Conventional Engine Oil
Conventional engine oil is the most common type of engine oil. It’s a blend of petroleum-based hydrocarbons and additives that provide lubrication and protection to the engine. Conventional engine oil is suitable for most passenger vehicles and is available in various viscosities, including 0W-20, 5W-20, and 5W-30.
Characteristics of conventional engine oil:
- Lubricates engine components
- Prevents corrosion
- Helps to regulate engine temperature
- Available in various viscosities
Synthetic Engine Oil
Synthetic engine oil is a high-performance oil that’s designed for high-performance vehicles or extreme driving conditions. It’s made from chemical compounds that provide superior lubrication and protection to the engine. Synthetic engine oil is more expensive than conventional engine oil but offers better fuel efficiency and engine protection.

- Provides superior lubrication and protection
- Resists breakdown and wear
- Improves fuel efficiency
- More expensive than conventional engine oil
Synthetic Blend Engine Oil
Synthetic blend engine oil is a blend of conventional and synthetic oils. It offers a balance of performance and price, making it a popular choice for many car owners. Synthetic blend engine oil provides better lubrication and protection than conventional engine oil but is less expensive than full synthetic engine oil.
Characteristics of synthetic blend engine oil:
- Provides better lubrication and protection than conventional engine oil
- Less expensive than full synthetic engine oil
- Available in various viscosities
Full Synthetic Engine Oil
Full synthetic engine oil is a high-performance oil that’s designed for high-performance vehicles or extreme driving conditions. It’s made from 100% synthetic compounds that provide superior lubrication and protection to the engine. Full synthetic engine oil is the most expensive type of engine oil but offers the best fuel efficiency and engine protection.
Characteristics of full synthetic engine oil:
- Provides superior lubrication and protection
- Resists breakdown and wear
- Improves fuel efficiency
- Most expensive type of engine oil
Viscosity of Engine Oil
Viscosity is a measure of the thickness and flowability of engine oil. It’s measured in centistokes (cSt) or Saybolt Universal Seconds (SUS). The most common viscosities for engine oil are:
| Viscosity | Description |
|---|---|
| 0W-20 | Thin oil for cold weather and high-performance vehicles |
| 5W-20 | Medium oil for most passenger vehicles |
| 5W-30 | Thick oil for high-performance vehicles and extreme driving conditions |
| 10W-30 | Thick oil for heavy-duty vehicles and extreme driving conditions |
Additives in Engine Oil
Engine oil additives are chemicals that are added to the oil to provide additional benefits. Some common additives in engine oil include: (See Also: Napa 1734 Oil Filter Fits What Vehicle? Compatible Vehicle List)

- Dispersants: Help to prevent the formation of deposits and sludge
- Anti-wear agents: Help to prevent wear and tear on moving parts
- Friction modifiers: Help to reduce friction and improve fuel efficiency
How to Choose the Right Engine Oil for Your Car
Choosing the right engine oil for your car depends on several factors, including:
- Vehicle manufacturer’s recommendations
- Driving conditions (e.g. extreme temperatures, high-performance driving)
- Engine type (e.g. gasoline, diesel, hybrid)
- Viscosity requirements
To choose the right engine oil for your car, follow these steps:
- Check your vehicle’s owner’s manual for the recommended engine oil type and viscosity
- Consider your driving conditions and engine type
- Choose an engine oil that meets your needs and budget
- Check the oil’s viscosity and additives to ensure they meet your requirements
Regular Oil Changes
Regular oil changes are essential to maintain the health and longevity of your car’s engine. It’s recommended to change your engine oil every 5,000 to 7,500 miles, depending on your vehicle’s manufacturer’s recommendations and driving conditions.
To check your car’s oil level, follow these steps:
- Turn off the engine and let it sit for a few minutes

Frequently Asked Questions (FAQs)
What type of engine oil should I use in my car?
The type of engine oil you should use in your car depends on several factors, including your vehicle’s manufacturer’s recommendations, driving conditions, and engine type. It’s best to check your owner’s manual or consult with a mechanic to determine the best engine oil for your car.
Can I use synthetic engine oil in my conventional engine?
Yes, you can use synthetic engine oil in your conventional engine, but it’s not necessary. Synthetic engine oil is designed for high-performance vehicles or extreme driving conditions, and it may not provide any additional benefits for your conventional engine.
