Types of Oil
The most common types of oil used in cars are:
- Conventional Oil
- Synthetic Oil
- Synthetic Blend Oil
- Full Synthetic Oil
- High Mileage Oil
- Diesel Oil
- Motor Oil for Classic Cars
Conventional Oil
Conventional oil is the most widely used type of oil in cars. It’s made from refined petroleum and is designed for use in conventional engines. Conventional oil is available in various viscosities, such as 0W-20, 5W-20, and 10W-30.
Conventional oil is suitable for most cars, but it may not provide the best protection for high-performance engines or engines that operate in extreme temperatures.
Synthetic Oil
Synthetic oil is a high-performance oil that’s designed for use in high-performance engines or engines that operate in extreme temperatures. It’s made from chemical compounds that provide better lubrication and wear protection than conventional oil.
Synthetic oil is available in various viscosities, such as 0W-20, 5W-20, and 10W-30. It’s more expensive than conventional oil, but it provides better engine protection and fuel efficiency.
Synthetic Blend Oil
Synthetic blend oil is a blend of conventional and synthetic oil. It’s designed to provide the benefits of synthetic oil at a lower cost. Synthetic blend oil is suitable for most cars and provides better engine protection than conventional oil.
Synthetic blend oil is available in various viscosities, such as 0W-20, 5W-20, and 10W-30.
Full Synthetic Oil
Full synthetic oil is a high-performance oil that’s designed for use in high-performance engines or engines that operate in extreme temperatures. It’s made from 100% synthetic compounds and provides better lubrication and wear protection than synthetic blend oil. (See Also: How Far Can You Drive On Low Engine Oil? Risks Involved)
Full synthetic oil is available in various viscosities, such as 0W-20, 5W-20, and 10W-30. It’s more expensive than synthetic blend oil, but it provides better engine protection and fuel efficiency.
High Mileage Oil
High mileage oil is designed for use in cars with high mileage (over 75,000 miles). It’s formulated to condition seals and gaskets, reduce oil consumption, and provide better engine protection.
High mileage oil is available in various viscosities, such as 5W-20 and 10W-30.
Diesel Oil
Diesel oil is designed for use in diesel engines. It’s formulated to provide better lubrication and wear protection than conventional oil.
Diesel oil is available in various viscosities, such as 5W-20 and 10W-30.
Motor Oil for Classic Cars
Motor oil for classic cars is designed for use in older cars with older engines. It’s formulated to provide better lubrication and wear protection than conventional oil.
Motor oil for classic cars is available in various viscosities, such as 10W-30 and 20W-50.
Viscosity
Viscosity is a measure of an oil’s thickness and flowability. It’s measured in units of centistokes (cSt) or Saybolt Universal Seconds (SUS).
Viscosity is important because it affects an oil’s ability to lubricate an engine’s moving parts. Thicker oils provide better lubrication, but they can be more difficult to pump and may not flow well in cold temperatures.
The most common viscosities used in cars are: (See Also: Why Does My Car Burn Oil Fast? Common Causes Revealed)
- 0W-20
- 5W-20
- 5W-30
- 10W-30
- 10W-40
- 15W-40
- 20W-50
When choosing an oil, it’s essential to consider the viscosity of the oil and the temperature range in which your car will operate.
API Certification
API (American Petroleum Institute) certification is a mark of quality that indicates an oil meets certain standards for performance and protection.
API certification is important because it ensures that an oil is designed to meet the needs of modern engines.
The most common API certifications are:
- API SN (Service Normal)
- API SN PLUS
- API CK-4
- API FA-4
When choosing an oil, look for the API certification mark on the label. This ensures that the oil meets the standards for performance and protection.
Oil Change Intervals
Oil change intervals vary depending on the type of oil used and the driving conditions. Here are some general guidelines:
| Oil Type | Oil Change Interval (miles) |
|---|---|
| Conventional Oil | 5,000-7,500 |
| Synthetic Oil | 7,500-10,000 |
| Synthetic Blend Oil | 5,000-7,500 |
| Full Synthetic Oil | 7,500-10,000 |
| High Mileage Oil | 5,000-7,500 |
| Diesel Oil | 5,000-7,500 |
It’s essential to check your owner’s manual for the recommended oil change interval for your car.
