About the 1987 Subaru 4-DOOR

Your 1987 Subaru 4-DOOR runs the 1.8L boxer engine, a design Subaru has refined for decades. The flat-four layout keeps weight low and makes the car handle better than its competitors, but it also means the engine depends heavily on good oil circulation. The crank and bearings sit low, and every component relies on a strong oil film.

Subaru owners who run AMSOIL consistently report cleaner engines and quieter cold starts. The is not a fragile engine, but it is old enough now that oil choice matters more than it did when the car was new. Sludge is the enemy of a boxer, and a high-detergent synthetic is the best defense.

AMSOIL Signature Series provides the deposit control and thermal stability this engine needs, and its extended drain capability means you can follow the manufacturer schedule with confidence.
