Things To Consider Before Picking The Best Oil For WRX STI

Every oil type is not designed to pour into your Subaru WRX. So, going for any random oil will not perform the best. So, consider the following things before purchasing oil for your WRX.

1. Viscosity

The first criterion you must take into account is the oil viscosity. It’s the thickness of oil and how the oil will flow in low temperatures. Generally, Subaru recommends these oil viscosity- 0w-20, 5w-20, and 5w-30 for all of its cars. So, check the specific car manual and pick the viscosity grade your Subaru needs. 

2. Subaru WRX Oil Consumption

How consistently you change your engine oil will help you figure out the oil consumption of your Subaru WRX. According to Subaru, you should change the oil after 6 months for the first time. Make sure you don’t cross 6K miles.

So, it will be better if you change the oil between 3k-4k miles. It’s a must to change the oil as a new car will experience wear in this period. So, change your engine at the right time, and maintain the car manual guide. 

3. Different Types Of Motor Oils

You can find different types of oil for your engine. Let’s check out what oil is best for what. Convention premium oil is perfect for every new vehicle. However, most car manufacturers recommend 5W-30 synthetic oil to let the engine run smoothly in low-temperature conditions. 

Full synthetic oil will be your go-to oil option for a lightweight vehicle. Such a type of oil performs the best both in low and high temperatures conditions. 

Synthetic blend oil is specially formulated for handling high heat conditions and heavier loads. High mileage oil is perfect for older engines with over 75k miles. 

4. Oil Additives For WRX STI

Oil additive is specially formulated to improve oil performance. You can find different types of oil additives. For example, anti-wear additives will help to protect your engine against wear & corrosion. 

On the other hand, detergent-based oil additives will deliver optimum engine protection against build-ups and deposits. Fortunately, every oil brand now includes additives in the oil. So, you don’t need to get oil additives separately.
