It’s critical that you use the correct motor oil if you want to keep your Subaru running well for a long time. Not all oils are made equal. It’s critical not just to use synthetic oil, but also to make sure it has the proper certifications, such as API SN, SN+, or SM. Proper maintenance with appropriate materials is crucial in order to extend the life of your car’s engine.
Because turbocharged vehicles are more susceptible to ignition knock, this is all the more critical in one like the WRX. For cars with the WRX engine, we suggested an API SN Plus-rated oil. The objective of these is to prevent low-speed preignition in directed-injected turbo engines such as the FA20DIT.
5W-30 synthetic is the suggested oil type for all versions of the WRX and WRX STI. We’ve compiled a list of the finest engine oils and evaluated their performance below.

Subaru WRX Generations
Subaru WRX 2018 (2018, 2019, 2020), 2nd generation
Subaru’s WRX 2nd generation is classified as a sedan. The WRX was separated from the Impreza lineup, becoming an all-wheel-drive performance vehicle that became a major model for the company. For the first time, a standard model received a new 2.5-liter turbocharged four with 310 horsepower and direct injection, replacing the previous car’s four-cylinder engine. It also departed from previous vehicles in offering an automatic option and a continuously variable transmission (CVT). A six-speed manual transmission was standard for the first time, compared to prior models’ five-speed unit

The WRX, which was introduced in 2004 and is powered by a 2.0-liter Horizontally-Opposed direct injection turbo “DIT” engine with a body and chassis considerably reinforced, reigned supreme in the field of high power and superb environmental friendliness. Sport Lineartronic, which had previously been implemented only on manual transmissions, has now been added to the transmission options for vehicles with 1998 cc engines producing 200 kW (272 hp).
Types of Oil for Subaru WRX
There are several motor oils suited for various sorts of cars. In the text below, we’ll look at each of them in depth.
Conventional Premium
Conventional premium oils are best used in new vehicles, and all of the top automobile manufacturers have their own with an SL service description. All oils are available in different viscosity levels. However, most automobile manufacturers advocate 5W-30 or 5W-20 for colder climates and 10W-30 for warmer climes. This category covers all light-duty vehicles that may be found on the road.
Full Synthetic
Full synthetic oils are recommended for more specialized lightweight vehicles. These oils have been subjected to a range of stability and performance tests for dependability, with different labeling indicating they’ve passed them all. They flow at both high and low temperatures. Because they are rather costly, not every vehicle owner can use them.
Synthetic Blend
SUV and truck owners like gasoline engines, since they have special synthetic oils designed for high temperatures and increased loads. As a result, these fluids are less volatile and provide better oil loss protection. Because these oils are not as combustible as full synthetics, they are considerably less expensive.
High Mileage
Because of modern technology, automobiles live longer and are more durable, which is why you see a lot of used cars on the road and for sale. Because of its age, your car will need a quart more oil than it did when it was new.
