What is the Subaru engine additive?

The Subaru engine additive is a product designed specifically for Subaru vehicles to improve engine performance and maintain the cleanliness of the engine components. It comes in different forms, including fluids and fuel additives, and serves various purposes depending on the specific additive used.
One example of a Subaru engine additive is the fluid used for automatic transmission and power steering systems in pre-2006 MY 4 EAT Subaru vehicles. This fluid contains an advanced additive package that provides optimum shift quality and maintains superior pump flow characteristics needed by the power steering system.
Another example is the Subaru fuel additive, which has been formulated to suit the special design of the horizontally opposed Boxer engine featured in Subaru vehicles. When mixed with fuel, this additive helps decarbonize the inside of the engine, keeps the valves cleaner, and improves the stability of the air-fuel mixture, resulting in easier engine starts.
It’s important to note that Subaru has not tested the compatibility or effectiveness of any oil additives, and the usage of such additives is at the owner’s discretion. If an engine failure occurs due to the incompatibility or performance of an additive, the vehicle owner may need to seek reimbursement from the additive manufacturer for the cost of the repair.
In summary, Subaru engine additives are designed to enhance engine performance, maintain cleanliness, and improve the overall operation of Subaru vehicles. However, it’s important to follow Subaru’s recommendations and guidelines regarding the use of additives to avoid any potential issues.

Do fuel additives actually clean your engine?

On ordinary Subaru family vehicles like the Ascent and Forester, regular gas is all you’ll need. However, the engines found in the Subaru BRZ, the Subaru WRX, and the Subaru WRX STI are built for higher compression with a powerful turbocharger — as a result, regular fuel can be problematic in these engines.
