Does Subaru have active fuel management?

Subaru vehicles have an engine management system that constantly monitors the state of combustion inside the cylinders. This system includes knock sensors that relay information to the engine management system, allowing it to automatically adjust the ignition timing to make the best use of the fuel in the tank. However, it is important to note that this system is not referred to as “active fuel management” in Subaru vehicles.
It is worth mentioning that Subaru recommends using the appropriate grade of fuel for each specific model. For example, the Subaru WRX and BRZ models are designed to operate using unleaded gasoline with an octane rating of 91 or higher, while the higher performance Subaru WRX STI requires 93 octane gasoline for optimal performance. Other Subaru models, such as the Outback, Impreza, and Forester, have different fuel requirements, ranging from 91 RON unleaded petrol to 95 RON unleaded petrol.
In summary, while Subaru vehicles have an engine management system that adjusts ignition timing based on the fuel in the tank, they do not have a specific feature called “active fuel management.” It is important to use the recommended grade of fuel for each Subaru model to ensure optimal performance and avoid potential issues [[6]].
