3 Types of Oil for Your Car


When it comes to maintaining your car’s engine, one of the most critical aspects is choosing the right oil. There are several different types of car oil available, and each one has unique characteristics and properties. Below, the friendly team from Altra Insurance Services, the auto insurance pros San Diego drivers trust for outstanding service, take a closer look at the three main types of car oil and what makes them different from each other.

1. Conventional Oil

Conventional oil, the type of oil used most commonly in cars today, is the most basic form of engine oil, and it’s made from crude oil that has been refined and processed. It’s also the most affordable option, but it has the shortest life span compared to the other two types of oil. This type of oil is perfect for cars used for daily commutes, errands, and short trips.

Conventional oil also comes in different grades, such as 5W-20, 5W-30, and 10W-30, to name a few. These grades represent the oil’s viscosity, which determines how easily it can flow through the engine at different temperatures. Lower-viscosity oils (like 5W-20) are best for colder climates, while higher-viscosity oils (like 10W-30) are better for warmer climates.

2. Synthetic Oil

Synthetic oil is a type of oil created in a laboratory, and it’s designed to provide better performance and protection than conventional oil. It’s made up of a combination of different chemicals, and the composition can vary depending on the brand and type. Synthetic oil is more expensive than conventional oil, but it lasts longer and offers better engine protection.

One of the main benefits of synthetic oil is its ability to withstand high temperatures. This means it can maintain its viscosity and protect the engine even in extreme conditions. Synthetic oil also has a more consistent molecular structure, which means it can flow more easily through the engine, reducing friction and wear on the engine’s parts.

3. High-Mileage Oil

As the name suggests, high-mileage oil is designed for cars that have traveled more than 75,000 miles. This type of oil contains additives that reduce oil consumption and minimize engine leaks. It’s also formulated to reduce engine wear and tear, which can be more common in older cars.

High-mileage oil is typically a synthetic blend, which means it combines conventional and synthetic oils. This combination of oils provides greater protection for the engine while still being affordable. Some high-mileage oils also contain seal conditioners that can prevent leaks in the engine.

Choosing the Right Type of Car Oil

When it comes to choosing the right type of oil for your car, there are several factors to consider. First, you should consult your owner’s manual to determine the recommended type of oil for your vehicle. The manufacturer’s recommendations are based on the specific needs of the engine and will ensure optimal performance.

Next, you should look at your driving habits and the conditions in which you drive. If you frequently drive in extreme temperatures or do a lot of heavy towing or hauling, synthetic oil may be a better choice. If you’re on a tight budget, conventional oil may be the most affordable option.

Finally, consider the age and condition of your vehicle. Older vehicles that were designed to use conventional oil may not be able to tolerate synthetic oil, which can cause leaks or other issues. In these cases, semi-synthetic oil may be the best choice.

In addition to choosing the right type of oil for your car, having adequate auto insurance is essential to protect yourself and your investment.
