20 Best Oil For Subaru Sti (2022 Updated)

Oil is the lifeblood of your car, and the Subaru STI is no different. It keeps all the moving parts in your engine lubricated, cooled and running smoothly. Not to mention, it helps protect your engine from premature wear and tear.

Over time, oil breaks down and loses its ability to do its job as effectively. That’s why it’s important to change your oil regularly, according to your car’s specific maintenance schedule.
