How to Choose the Best Engine Oil for Your Vehicle

Viscosity

An engine oil’s viscosity means the speed at which different fluids flow in directions. Viscosity grade or oil grade is the measurement of an oil's flow resistance. When looking for the best engine oil, it is crucial to take into account this aspect in addition to the weather and driving conditions.

A higher number denotes a higher viscosity, which indicates that the diesel engine’s oil grade is more viscous and flow-resistive.

Importance of Viscosity in Engine Oil

• The engine will become unresponsive if the viscosity is too high. In order for the oil to reach important engine components, the engine must use greater force in order to break through the oil's flow barrier.
• At lower temperatures, thin, low viscosity oils can flow more easily to shield engine components.
• At high temperatures, high viscosity, thick lubricants are often better at protecting film strength to safeguard engines.

By checking the oil cap or the owner's handbook, you may find out the right viscosity for your car.

Synthetic Oil

Pros:

• Excellent chemical and thermal stability
• Outstanding engine protection
• Need no oil changes for more than 10,000 kilometers
• High heat and oxidation resistance.
• Improved anti-friction qualities
• Better fuel efficiency and responsiveness of the engine
• Helps the engine to last longer
• Useful for navigating city traffic that is stop-and-go

Sigma oil is a fully synthetic oil that protects your engine from dirt, waste and sludge. Their oil has a good flowing rate at low temperature, giving a good fuel economy

Cons:

• Relatively low solubility
• Comparatively high cost

Semi-Synthetic

Has the benefits of both mineral and synthetic oil.

Driving Environment

Choosing the proper engine oil requires careful consideration of the weather and driving circumstances.

Your vehicle may be put under strain in many ways depending on the weather conditions. When determining which engine oil is best for you, it's crucial to take into account your local driving and environmental conditions.

Heavy-duty engine oils from Sigma Oil deliver optimal and reliable performance even in challenging operating circumstances.

OEM Specifications

A base oil and additive mixture that is tailored to the needs of the engine is used to create Original Equipment Manufacturer (OEM) authorized oil. An engine oil’s quality gets tested and if found to satisfy specifications, are then being submitted to the vehicle manufacturer.

Oil Standards

The American Petroleum Institute (API) and ACEA are the most widely used standards (European Automobile Manufacturers Association).

Specifications are crucial since they reveal the functionality and caliber of the oil.
