One of the oil engine attributes you’ll hear a lot about is viscosity. Here’s what you need to know:
Understanding viscosity
Viscosity, in layman’s terms, is the measure of an oil’s resistance to flow. It is often described using two numbers, such as 10W-40. The first number represents the oil’s viscosity at cold temperatures, and the “W” stands for winter. The second number denotes how the oil will flow at high temperatures.
API engine oil classification
The API categorizes engine oils based on their performance specifications, whether for gasoline engines (indicated by “S” for Spark ignition) or diesel engines (indicated by “C” for Compression ignition).
SAE viscosity grades
The Society of Automotive Engineers (SAE) has viscosity grades for engine oils. These grades, such as SAE 5W-30 or SAE 10W-40, tell you the viscosity of the oil at both cold and high temperatures respectively.
Determining the right viscosity grade for your vehicle
The right viscosity grade for your vehicle would depend on a combination of factors including manufacturer recommendations, engine condition, ambient climate, and your driving habits.
Different Types of Engine Oil
Now that you have a solid understanding of what engine oil is, its functions, and things to consider, let’s delve into the different types.
Conventional oil
A staple in many older cars, conventional oil is composed of base oils enhanced with a variety of chemical additives.
Synthetic oil
Made from base oils and a set of specially engineered additives, synthetic oils perform exceptionally well in extreme temperatures and offer longer change intervals.
High mileage oil
As the name suggests, high mileage oil is ideal if your odometer reads over 75,000 miles. These oils have seal conditioners to keep the engine running smoothly.
Full synthetic oil
A gold standard for engine oils, full synthetic oil is engineered to deliver superior engine protection, cleanliness, and performance even under severe driving conditions.
Synthetic blend oil
These blend conventional and synthetic oils to offer enhanced resistance to oxidation and good low-temperature properties.
Performance Specifications
Performance specifications are measures of an engine oil’s quality, efficiency, and ability to protect a vehicle’s engine. Here are some commonly used certifications:
API (American Petroleum Institute) certification
An API certification signifies the oil meets the institute’s guidelines in terms of performance, efficiency, and environmental impact.
ACEA (European Automobile Manufacturers Association) specification
ACEA sets performance standards for engine oils and ensures they meet the specific demands of European cars.
ILSAC (International Lubricants Standardization and Approval Committee) certification
ILSAC standards are commonly adopted by Asia and North American car manufacturers. They factor in engine oil efficiency and emission system protection.
