When they search for a WRX STI for sale, Perth drivers are often focused on the performance aspects of this stunning performance saloon car. However, every car needs oil to function correctly, and the WRX STI is no exception. Sadly, many drivers ignore the oil needs of their cars and their performance suffers. In this article, we will look at the importance of a regular oil and oil filter change.

The Importance of Oil in Your Engine

The oil that circulates around the engine, keeps all of the moving parts lubricated to prevent wear when they make contact with other parts. If there isn’t enough oil in the engine, the car owner will soon notice that parts wear out faster than they should. This will result in buying parts more often than necessary and eventually there could be an expensive repair bill.

Why Does Oil Need Changing Regularly?

Over time, dirt and particles from the engine components will gradually build up in the oil. As the particle content increases the viscosity of the engine oil will degrade and the less effective it will be as a lubricant. So, periodically it’s essential to drain the oil out of the system and replace it with fresh oil that’s free from contaminants. If you’ve ever seen old dark, dirty oil draining from your engine and compared it to fresh oil, you will quickly notice the difference. If the oil in your WRX STI is changed in accordance with Subaru recommendations, you will save a great deal of money on worn out part over the years of ownership.

How Often Should OIl be Changed?

When you look at a Subaru WRX for sale, it will come with oil already in the system. Over time the oil level will drop, and the system will need to be topped up to keep the parts lubricated. The type of oil that you need to use and how to do this is detailed in the owner’s manual. But, when should a full oil change take place? This is also covered in the manual, and it will be an essential part of your Subaru service. If you’re uncertain about the whether you need to change the oil in your WRX STI more often ask your Subaru service advisor for advice.

Why Would the Oil Change Interval Differ?

The WRX STI owner’s manual recommends an oil change at 10,000km or six month intervals. Some drivers engaged in harder drivers could half this interval to stay on the safe side. How you drive your WRX STI and where you live or drive it most can have a dramatic effect on your oil change intervals. Here in Western Australia, we don’t do a lot of driving in sub-zero temperatures, and we don’t have to worry about the resulting corrosive salt spread on our roads. But, we do get dusty driving conditions and low speed driving over long distances in heavy traffic can take a toll. If you’re unsure about your oil change interval get some expert advice at your next Subaru service.
