What Oil Do I Need For My Car?

When it comes to maintaining your car’s engine, one crucial aspect is choosing the right oil. With the multitude of options available in the market, finding the perfect oil for your vehicle can seem overwhelming.

Here at Asda Motoring, we will simplify the process and provide you with a comprehensive guide to help you determine the oil that best suits your car’s needs.

Understanding Oil Viscosity

Viscosity is a critical factor to consider when selecting the appropriate oil for your car. It refers to the oil’s resistance to flow and is typically denoted by a number and the letter “W” (e.g., 5W-30). The “W” stands for winter, and the number preceding it represents the oil’s viscosity at low temperatures. The second number denotes viscosity at normal operating temperatures.

Your car’s owner’s manual will often recommend a range of acceptable viscosities based on your driving conditions. For colder climates, a lower first number is preferable, while hotter climates may require a higher second number. Striking the right balance is essential for ensuring optimal engine performance and protection.

Types of Engine Oil

  • Conventional Oil: Conventional oil is the most common and widely available type of motor oil. It is suitable for everyday driving conditions and offers adequate engine protection. However, it may require more frequent oil changes compared to synthetic oils.
  • Synthetic Oil: Synthetic oils are engineered to provide superior performance and protection. They offer improved resistance to breakdown, better viscosity stability, and enhanced lubrication even in extreme temperatures. Synthetic oils are ideal for high-performance vehicles, towing applications, and harsh driving conditions. Although more expensive, they often provide longer service intervals.
  • Synthetic Blend Oil: Synthetic blend oils, as the name suggests, are a mixture of conventional and synthetic oils. They strike a balance between performance and affordability, making them a popular choice among car owners. Synthetic blends can offer improved protection during high-stress situations and are suitable for light trucks, SUVs, and vehicles that tow moderate loads.

Considering Oil Additives

Oil additives are chemical compounds that enhance the oil’s properties and performance. While many modern oils already contain additives, some specific requirements may necessitate additional additives. For instance:

  • High-Mileage Oil: If your car has accumulated a high mileage (typically over 75,000 miles), consider using high-mileage oil. It contains additives that condition ageing engine seals and prevents oil leaks.
  • Synthetic Blend with Friction Modifiers: Friction modifiers reduce engine wear and enhance fuel efficiency. If you have a newer vehicle that requires oil with friction modifiers, a synthetic blend oil may be a suitable choice.

Consulting the Owner’s Manual

Your car’s owner’s manual is a valuable resource that should never be overlooked. It provides manufacturer-recommended oil specifications, including the viscosity and any specific requirements for your vehicle. Following the manufacturer’s recommendations ensures that you maintain your car’s warranty and guarantees optimal engine performance.

Choosing the right oil for your car is crucial for maintaining its engine’s longevity and performance. By understanding viscosity, exploring different oil types, considering additives, consulting your owner’s manual, and looking for the appropriate API certification, you can confidently make an informed decision. Remember, regular oil changes using the correct oil will keep your car running smoothly, maximising its lifespan and ensuring a reliable driving experience.
