Hunting for the best oil brand for Subaru?
The best way to ensure that the engine of your Subaru Forester, Ascent, Outback or Legacy remains reliable for years is to use Subaru engine oil. As you already know, motor oil is “blood” for your car engine. Without it, your engine will not cool properly, resulting in wear and damage. Also, the lubrication of moving parts will not happen as well as the removal of harmful contaminants.
According to experts at Subaru, you should change your first motor oil after 3,000 to 4,000 miles. Why you may ask? Well, the initial break-in period for a new car engine is 3,000 miles. Failure to change the motor oil after the first 3,000 miles, your car engine will experience more wear.
Choosing the best motor oil for Subaru can be overwhelming, especially for a first-time car owner. Worry not. In our comprehensive Subaru engine oil guide, we review the best motor oil brand for Subaru, what to consider before buying and FAQs.

Best Oil Brand for Subaru Buying Guide
There are several things to consider before you buy the best oil for Subaru. A garage would be a great place to start, but if you don’t live near such a shop, why risk your Subaru by driving on low-quality motor oil. Here are things to consider before buying the best motor oil for Subaru.
Viscosity simply means a fluid’s resistance to flow. On the label of any motor oil container, you should find the following numbers (0W-20) or (5W-40). According to the Society of Automotive Engineers (which sets stands for viscosity rating of motor oils), W stands for winter. This means the motor oil meets excellent low-temperature performance.
The value before (W) stands for cold temperature performance. At the same time, the end number (20) indicates high-temperature performance at 100 degrees Celcius. Thicker oil seals better and helps to provide a better film of protection for your moving parts. When buying motor oil, it’s essential to use only what the car manufacturer recommends.
Every motor oil container comes with two labels on each side of the container. Not only do the labels contain the brand name, type of oil, viscosity grade, and quantity. They also have useful information, which indicates if the oil has passed the required tests and what to do in case of contact with skin or eyes.
As a shopper, it’s essential to read the label. Failure to do so may lead to you buying the wrong product for your Subaru. And you know what may happen to your car engine. Take your time to read the information, and if you have any questions, you can always rely on the manufacturer’s customer support team.
Type of Oil
There are several types of motor oil. You have premium conventional oil, full synthetic oil, synthetic blend oil, and high mileage oil. Premium conventional oil is the standard motor oil for new cars. The oil has one service level on the label available in several viscosities, such as 0W-20 or 5W-20.
Full synthetic oil is best for high tech engines such as Subaru, Mercedes, Corvette, and others. The motor oil has a superior and long-lasting performance. It offers protection against harmful deposits. The oil also helps to maintain peak lubricity at high temperatures.
Synthetic blend oil is usually mixed with organic oil and protects against high temperatures and heavier loads. Last, we have high mileage oil. This type of oil is best for high mileage vehicles. So, if you want your odometer to read six figures, high mileage oil is for you.
